Prometheus client lib support gzip by itself. Which caused the
response to be double gzipped sometimes. We should use the Grafana
middle ware instead.

I renamed `tlsAuth` to `tlsClientAuth` to better describe the fact that
this variable is used to enable TLS client authentication (as opposed to
server authentication) in c04d95f35.
However, changing the name breaks backwards compatibility for existing
installations using this feature and Grafana does not have a
standardised way of migrating changes in the schema:
https://github.com/grafana/grafana/pull/9377#issuecomment-333063543
For reasons of expediency given the severity of the bug (not verifying
TLS), keep the old name.
In c04d95f35 I changed the default for datasource HTTP requests so that
TLS is always verified.
This commit adds a checkbox to allow an admin to explicitly skip TLS
verification, for testing purposes.

It should be specify to either use TLS client authentication or use a
user-supplied CA; previously you had to enable client authentication to
use a custom CA.
If either is set, try to use them.
This should help avoid a situation where someone has half-configured TLS
client authentication and it doesn't work without raising an obvious
error.
TLS was not being verified in a number of places:
- connections to grafana.com
- connections to OAuth providers when TLS client authentication was
enabled
- connections to self-hosted Grafana installations when using the CLI
tool
TLS should always be verified unless the user explicitly enables an
option to skip verification.
Removes some instances where `InsecureSkipVerify` is explicitly set to
`false`, the default, to help avoid confusion and make it more difficult
to regress on this fix by accident.
Adds a `--insecure` flag to `grafana-cli` to skip TLS verification.
Adds a `tls_skip_verify_insecure` setting for OAuth.
Adds a `app_tls_skip_verify_insecure` setting under a new `[plugins]`
section.
I'm not super happy with the way the global setting is used by
`pkg/api/app_routes.go` but that seems to be the existing pattern used.
This modification aim to allow users to set value via textMapping and
these values to be used in background coloring as it text coloring.
This pull request closes#8404, but doesn't agree with #9012.
The issue #9012 consider that no coloring output should be put when
there is no data. I partially agree with this as I explicitely setted a
value in the textMapping I obviously want to treat `N/A` as a number.
`data.valueFormatted` contain the stringified version of `data.value`
If `Number()` cannot convert a string into a number a `NaN` value is
returned. So the code is still valid if the inputted value in
`data.valueFormatted` is not a number.
This changes introduce milliseconds format option in table panel
config GUI. Current grafana support milliseconds in time and
actually used at graph panel, however current table does not
provide the way to show milliseconds. This fix is to add format
in table panel to show milliseconds in table as well as graph.

Unfortunately CloudWatch dimensions are case-sensitive and it uses both `DBClusterIdentifier` and `DbClusterIdentifier` (notice the lower case `b`) depending on the metric. All metrics which also have the `Role` dimension appear to use `DBClusterIdentifier`, whereas metric with the `EngineName` dimension use `DbClusterIdentifier`.
Summary:
Previously, cloudwatch data sources would only fill in a single null value if
there was missing data. This results in behavior described in #9267. This
resolves that issue by filling the entire missing period with null values. The
null values can then be interpreted as normal by the graphing frontend.
Test Plan:
Used on a data source that had missing data for many consecutive periods.
Ensured that the graph remained at 0 across the entire window.
* Prometheus: Fix actual step computation logic when a min_step is specified and the range is longer than min_step * 11000.
* Fix kbn.round_interval for exact intervals.
* Remove redundant 1d return, fix a couple of comments.
* Be more cautious with values close to 1d not rounding up to 1d. They may, because of the way the calculation uses 2 potentially different current time values.
* Prometheus: Fix actual step computation logic when a min_step is specified and the range is longer than min_step * 11000.
* Have the 'Hide series with only zeros' option also apply to series with some null values.
The generated queries when selecting multiple tags are incorrect. In
InfluxQL, `AND` has a higher precedence than `OR` so the condition:
WHERE "hostname" = 'server1' OR "hostname" = 'server2' AND time > now() - 5m
This is parsed as if it were:
WHERE "hostname" = 'server1' OR ("hostname" = 'server2' AND time > now() - 5m)
But the intention is to write a query like this:
WHERE ("hostname" = 'server1' OR "hostname" = 'server2') AND time > now() - 5m
This change modifies the generated query so it surrounds a query with
multiple conditions in parenthesis so it doesn't conflict with the time
expression in an unexpected way.
This is currently not an issue because InfluxDB doesn't actually
evaluate the condition for the time expression correctly. It just looks
through the AST for anything that looks like a time expression and then
assumes the proper format of `AND` was used rather than validating that
it was used correctly.
Raw query results would return as expected. But when appending new series to pointsBySeries map, order of keys is random. So I've added a list to keep track of series order. Should implement FIFO rules.
Adds back feature that adds 'sep=;' text that excel needs in a csv file.
Also adds toggle to make this optional if exporting to other spreadsheet
programs. Fixes#9083.
If the template variable query has two columns named __text and __value
then return a list of key values. The value is used when the variable is
interpolated in the query. Allows mapping of texts to ids.

Fixes#8872. Use the automatic calculation by Flot to get the
number of decimal places for ticks on the y-axis rather than
the number of decimal places for the min value.
Fixes#5515. Flot gauge has its own threshold check that is different
from the threshold check in singlestat. This changes the flot check to
be exclusive (same as the singlestat check). E.g. if the threshold is
10, then the value 10 is over the threshold.

If a dashboard has a null value for updated_by then the migration
for the dashboard version table fails. This change uses coalesce to
set -1 instead of null when inserting into the created_by column
which has a non-null constraint. Fixes#8783.

Changes to the http_server class meant that the TLS settings were not
getting applied anymore. This fixes so that the minimum TLS version is
1.2 again.
When table data returns a column with the value 0, it should not ignore
it. This change checks for undefined instead of if the value is truthy.
Fixes#8531
To be able to build the docs an awsconfig file must exist for the Dockerfile to copy. This adds an instruction to create an empty, dummy file so that the build will work.
Tags come back from AWS as a key value pair inside an array
This array is now converted to an object
Tags can be selected when using the 'ec2_instance_attribute' query
Example: `ec2_instance_attribute(us-east-1, Tags.Name, { "tag:Grafana": [ "true" ] })`
If there are too many ticks generated for the y-axis (which can occur
for log scale 2, with a small y-min and a large max), then the ticks
will be regenerated using larger jumps between the ticks.
This also handles the case when y-min is set to 0. Previously, y-min of
0 was ignored as zero is not a valid value for log scale. Now the tick
generator approximates zero by setting min to 0.1.

when switch to "raw Document" metric type we do free all "Group by"

when selecting Raw Documet metric type, the $scope.target.metrics was replaced by [$scope.agg],
however the pointer to this variables is shared with metricAggs.
Instead we free the array and add $scope.agg
fixes#8446. Data with all values equal to zero, creates a max with the
value of Infinite. The for loop for creating ticks then gets stuck in an
infinite loop. This fix resets min and max and creates some fake ticks
for the y-axis if the min and max are not finite numbers.

A simple version control system for dashboards. Closes#1504.
Goals
1. To create a new dashboard version every time a dashboard is saved.
2. To allow users to view all versions of a given dashboard.
3. To allow users to rollback to a previous version of a dashboard.
4. To allow users to compare two versions of a dashboard.
Usage
Navigate to a dashboard, and click the settings cog. From there, click
the "Changelog" button to be brought to the Changelog view. In this
view, a table containing each version of a dashboard can be seen. Each
entry in the table represents a dashboard version. A selectable
checkbox, the version number, date created, name of the user who created
that version, and commit message is shown in the table, along with a
button that allows a user to restore to a previous version of that
dashboard. If a user wants to restore to a previous version of their
dashboard, they can do so by clicking the previously mentioned button.
If a user wants to compare two different versions of a dashboard, they
can do so by clicking the checkbox of two different dashboard versions,
then clicking the "Compare versions" button located below the dashboard.
From there, the user is brought to a view showing a summary of the
dashboard differences. Each summarized change contains a link that can
be clicked to take the user a JSON diff highlighting the changes line by
line.
Overview of Changes
Backend Changes
- A `dashboard_version` table was created to store each dashboard
version, along with a dashboard version model and structs to represent
the queries and commands necessary for the dashboard version API
methods.
- API endpoints were created to support working with dashboard
versions.
- Methods were added to create, update, read, and destroy dashboard
versions in the database.
- Logic was added to compute the diff between two versions, and
display it to the user.
- The dashboard migration logic was updated to save a "Version
1" of each existing dashboard in the database.
Frontend Changes
- New views
- Methods to pull JSON and HTML from endpoints
New API Endpoints
Each endpoint requires the authorization header to be sent in
the format,
```
Authorization: Bearer <jwt>
```
where `<jwt>` is a JSON web token obtained from the Grafana
admin panel.
`GET "/api/dashboards/db/:dashboardId/versions?orderBy=<string>&limit=<int>&start=<int>"`
Get all dashboard versions for the given dashboard ID. Accepts
three URL parameters:
- `orderBy` String to order the results by. Possible values
are `version`, `created`, `created_by`, `message`. Default
is `versions`. Ordering is always in descending order.
- `limit` Maximum number of results to return
- `start` Position in results to start from
`GET "/api/dashboards/db/:dashboardId/versions/:id"`
Get an individual dashboard version by ID, for the given
dashboard ID.
`POST "/api/dashboards/db/:dashboardId/restore"`
Restore to the given dashboard version. Post body is of
content-type `application/json`, and must contain.
```json
{
"dashboardId": <int>,
"version": <int>
}
```
`GET "/api/dashboards/db/:dashboardId/compare/:versionA...:versionB"`
Compare two dashboard versions by ID for the given
dashboard ID, returning a JSON delta formatted
representation of the diff. The URL format follows
what GitHub does. For example, visiting
[/api/dashboards/db/18/compare/22...33](http://ec2-54-80-139-44.compute-1.amazonaws.com:3000/api/dashboards/db/18/compare/22...33)
will return the diff between versions 22 and 33 for
the dashboard ID 18.
Dependencies Added
- The Go package [gojsondiff](https://github.com/yudai/gojsondiff)
was added and vendored.
Please let me know if this changed in a more recent version of Grafana, but when using 4.2.0 the manual install directions were off a little (there was no `data/plugins` directory, only a `plugins` directory).

The bug was happening because the background color was being based on
the rounded value (accounting the user defined decimals). Changed it to
use the pure value (not the rounded) to follow whats being done in the
value color, and also in the table thresholds (they don't consider the
decimals when comparing to thresholds).
Avg column was being added at every rendering, if the table was empty.
Now the column will be added once as an initialization when selecting a
'timeseries_aggregations' transform.
Remove 5 lines from the codebase and an unecessary function,
by calling `strings.Replace` with -1 for the fourth argument.
A better alternative to what was merged in #8037
Removes dashes option from Display tab so that it is only available
for series overrides. Also removes options for dash space and length
in series overrides and just uses the default values of 10 for both of
them.
* refactor util encryption library so it doesn't have to import log
* add util.SplitString to handle space and/or comma-separated config lines
* go fmt
Previously `Step` parameter would set a hard value for any zoom level.
Now it's renamed to `Min step` and sets the minimal value of `step` parameter
to Prometheus query. User would usually want to set it to the scraping interval
of the target metric to avoid having shap cliffs on graphs and extra load
on Prometheus. Actual `step` value is calculated as the minimum of automatically
selected step (based on zoom level) and user provided minimal step. If user
did not provide the step, then automatic value is used as is.
Example bahavior for `60s` scrape intervals:
* `5s` automatic interval, no user specified min step:
* Before: `step=5`
* After: `step=5`
* `5s` automatic interval, `1m` user specified min step:
* Before: `step=5`
* After: `step=60`
* `5m` automatic interval, `1m` user specified min step:
* Before: `step=60` (not really visible, too dense)
* After: `step=300` (automatic value is picked)
See:
* https://github.com/grafana/grafana/issues/8065
* https://github.com/prometheus/prometheus/issues/2564
Tab size was added as 2 in .editorconfig but a tab size of 4 is used
throughout go code base.
This can cause editors such as vscode to automatically reformat open .go
files to tab size 2 from 4.
If grafana-server binary is started with the -profile flag then
tracing will create a trace.out file and pprof data can be accessed
on the 6060 port.
A custom port for pprof profiling can be set with the -profile-port
flag.

In systemd `After=` merely codes an ordering relation and does not start
other units.
Grafana needs to specify that it wants to start up _after_ either of the
supported DB services have started, _if they start_.
Enabling the database services, however, is out of scope for Grafana.
We now obtain credentials based on the container task's role
rather than just relying on the credentials of the enclosing
container instance.
Fixes#6700.
If the auth config variable, disable_login_form, is set to true then
the username and email fields are set to read-only on the profile page.
The reason for this is so that the user does not lock themselves out by
changing their email address or username. Or create a new user by
changing both.

Since upgrading to Angular 1.6.1, selects with a default empty option
no longer show a popup with an error on submit. This fix adds an
empty option that is then removed with ng-if. Having the default
option set to null or undefined seems to be the cause of the bug.

- Fix for when min/max were undefined rather than null
- Fix for decimal ticks, as this PR populates the ticks itself then
it also needs to calculate the number of decimal places too. Flot
was showing the wrong number of decimal places sometimes otherwise
on the y-axis.
Moves the logic up a level to the panel_ctrl. This cleans up the code
and makes the lazy loading available for all panels.
Removes the config option and making this default behavior. We can
add back the config option if we get feedback that it is needed during
the beta phase of the v4.3.0 release.
Unbind the scroll handler on panel destroy to avoid memory leaks.
Fix for png rendering, it did not match all forms of dashboard-solo.
e.g. /render/dashboard-solo/db...
Fix for when taking a snapshot. All the panels get refreshed then
even the panels that are not visible.
Closes#5216.
to make sure an user opens the dashboard in the correct org, orgId will
always be added when sharing a dashboard. if the users current orgId
doesnt match the query parameter grafana will change it and redirect the
user.
closes#1613
setup compiles the backend and caches it which is nice
when developing grafana since incremental compiles are
much faster. But its not required for building grafana.
Currently there is a limit of 1000 users in the global
user list. This change introduces paging so that an
admin can see all users and not just the first 1000.
Adds a new route to the api - /api/users/search that
returns a list of users and a total count. It takes
two parameters perpage and page that enable paging.
Fixes#7469

Sorts the list of metric sources that is used in dropdown for Panel
Data Source on the Metrics tab so that it is case insensitive and
so that the built data sources are last in the list.
The data source list is case sensitive when sorted. This changes the
sort to be case insensitive. The test only tests the handler, not the
routing or database query.
This commit adds alerting support for Threema Gateway. It supports all
Simple IDs (managed by the Gateway server).

* docs(plugins): new developing plugins section
Creates new section called Developing Plugins in
the plugin section of the docs.
1. Some changes to the Development guide page
2. Converted defaults/editor mode blog post
to new page
3. Converted snapshots blog post to new page
4. Adds new code styleguide page
5. Updates to apps and datasources pages
6. Adds plugin.json schema
* docs(links): fixes broken links
Fixes broken links to other pages as
well as broken image links.
I noticed tooltips on other panels rendering outside of their panel or
even the browser window when hovering on the very edge of graphs with
relative time overrides.
Some email providers does not accept localhost
in the HELO message. So we set it to hostname
instead. Our hope is that should be enough for
those providers who does not accept localhost.
closes#7223
* fix(alerting): fixed evaluation for no_value condition, fixes#7244
* feat(alerting): moving null library into grafana, fixing handling on no value / no series
With present postinst script on Centos 7, restart after upgrade is not working with Warning: grafana-server.service changed on disk. Run 'systemctl daemon-reload' to reload units.
So i added systemctl daemon-reload.
This enables Grafana to accept new users authenticated through OAuth, without this set to true only previously authenticated users may log in with OAuth - and thus defeating the purpose.
- adds the option to use ldap groups for authorization in combination with an auth proxy
- adds an option to limit where auth proxy requests come from by configure a list of ip's
- fixes a security issue, session could be reused
* Prettify duration unit format
Format duration like "2 days, 19 hours, 48 minutes" and make Decimals useful e.g.
0 decimals: 2 days
2 decimals: 2 days, 19 hours, 48 minutes
3 decimals: 2 days, 19 hours, 48 minutes, 27 seconds
Previous code did some rounding that is now gone so numbers might be
different.
* Rewrite kbn.toDuration without moment.js
Because https://github.com/moment/moment/issues/3653
* Add tests for kbn.toDuration
- Three text areas where the user can paste
in the CA Cert (optional), Client Cert
and Client Key.
- Tooltips for Auth checkboxes with brief
descriptions of what With Credentials and
With CA Cert are.
- Adds popover for TLS Auth header too.
- Aligns gf-form elements as labels and
checkboxes were not aligned before.
- Makes CA Cert optional as it is only
needed for self-signed certs.
The tls files are stored as a json blob in the
SecureJsonData field. To update one file, the
json has to be fetched from the db first and
then updated with the cert file that has been
changed.
Also, a change to the dto with flags that are
used in the frontend to show if a file has
been uploaded. For example, if tlsClientKeySet
is set to true then means a file for the
client key is saved in the db. This is to
avoid sending any private data to the frontend.
For self-signed TLS Certificates, authentication
with InsecureSkipVerify set to false then this
error will occur:
x509: certificate signed by unknown authority
The solution is to allow the user to upload the
CA cert as well.
Use a SecureJsonData field for TLS
Client Auth instead of 3 new db
fields. Same model as used for
PluginSettings.
Saves and encrypts the pem file
content rather than just saving
the paths to the cert and key.
This allows for uploading from
the Edit Datasource page in
Grafana.
So I decided to scrap that, and go for just having a hidden column style. This is what
@madshall did in his enhanced table pull request, so this is basically the hidden
column style feature form his pull request.

* **GitHub OAuth**: Support for GitHub organizations with 100+ teams. [#8846](https://github.com/grafana/grafana/issues/8846), thx [@skwashd](https://github.com/skwashd)
* **Graphite**: Calls to Graphite api /metrics/find now include panel or dashboad time range (from & until) in most cases, [#8055](https://github.com/grafana/grafana/issues/8055)
* **Graphite**: Added new graphite 1.0 functions, available if you set version to 1.0.x in data source settings. New Functions: mapSeries, reduceSeries, isNonNull, groupByNodes, offsetToZero, grep, weightedAverage, removeEmptySeries, aggregateLine, averageOutsidePercentile, delay, exponentialMovingAverage, fallbackSeries, integralByInterval, interpolate, invert, linearRegression, movingMin, movingMax, movingSum, multiplySeriesWithWildcards, pow, powSeries, removeBetweenPercentile, squareRoot, timeSlice, closes [#8261](https://github.com/grafana/grafana/issues/8261)
- **Elasticsearch**: Ad-hoc filters now use query phrase match filters instead of term filters, works on non keyword/raw fields [#9095](https://github.com/grafana/grafana/issues/9095).
### Breaking change
* **InfluxDB/Elasticsearch**: The panel & data source option named "Group by time interval" is now named "Min time interval" and does now always define a lower limit for the auto group by time. Without having to use `>` prefix (that prefix still works). This should in theory have close to zero actual impact on existing dashboards. It does mean that if you used this setting to define a hard group by time interval of, say "1d", if you zoomed to a time range wide enough the time range could increase above the "1d" range as the setting is now always considered a lower limit.
* **Elasticsearch**: Elasticsearch metric queries without date histogram now return table formated data making table panel much easier to use for this use case. Should not break/change existing dashboards with stock panels but external panel plugins can be affected.
## Changes
* **InfluxDB**: Change time range filter for absolute time ranges to be inclusive instead of exclusive [#8319](https://github.com/grafana/grafana/issues/8319), thx [@Oxydros](https://github.com/Oxydros)
* **InfluxDB**: Added paranthesis around tag filters in queries [#9131](https://github.com/grafana/grafana/pull/9131)

* **Templating**: You cannot select data source variables as data source for other template variables [#7510](https://github.com/grafana/grafana/issues/7510)
* **MySQL/Postgres**: Fix for max_idle_conn option default which was wrongly set to zero which does not mean unlimited but means zero, which in practice kind of disables connection pooling, which is not good. Fixes [#8513](https://github.com/grafana/grafana/issues/8513)
# 4.4.3 (2017-08-07)
## Bug Fixes
* **Search**: Fix for issue that casued search view to hide when you clicked starred or tags filters, fixes [#8981](https://github.com/grafana/grafana/issues/8981)

## Changes in v4.6
This version of Grafana has big changes that will impact a limited set of plugins. We moved from systemjs to webpack
for built-in plugins & everything internal. External plugins still use systemjs but now with a limited
set of Grafana components they can import. Plugins can depend on libs like lodash & moment and internal components
like before using the same import paths. However since everything in Grafana is no longer accessible, a few plugins could encounter issues when importing a Grafana dependency.
[List of exposed components plugins can import/require](https://github.com/grafana/grafana/blob/master/public/app/features/plugins/plugin_loader.ts#L48)
If you think we missed exposing a crucial lib or Grafana component let us know by opening an issue.
### Deprecated components
The angular directive `<spectrum-picker>` is no deprecated (will still work for a version more) but we recommend plugin authors
to upgrade to new `<color-picker color="ctrl.color" onChange="ctrl.onSparklineColorChange"></color-picker>`
To build less to css for the frontend you will need a recent version of **node (v4+)**,

Work in progress Grafana 2.0 (with included Grafana backend)
To build the docs locally, you need to have docker installed. The
docs are built using a custom [docker](https://www.docker.com/) image
and the [mkdocs](http://www.mkdocs.org/) tool.
docs are built using [Hugo](http://gohugo.io/) - a static site generator.
**Prepare the Docker Image**:
Build the `grafana/docs-base:latest` image. Run these commands in the
same directory this file is in. **Note** that you may require ``sudo``
Git clone `grafana/grafana.org` repo. Run these commands in the root of that repo. **Note** that you may require ``sudo``
when running ``make docs-build`` depending on how your system's docker
service is configured):
```
$ git clone https://github.com/grafana/docs-base
$ cd docs-base
$ make docs-build
git clone https://github.com/grafana/grafana.org
cd grafana.org
make docs-build
```
**Build the Documentation**:
Now that the docker image has been prepared we can build the
docs. Switch your working directory back to the directory this file
(README.md) is in and run (possibly with ``sudo``):
grafana docs and start a docs server.
If you have not cloned the Grafana repository already then:
```
$ make docs
cd ..
git clone https://github.com/grafana/grafana
```
Switch your working directory to the directory this file
(README.md) is in.
```
cd grafana/docs
```
An AWS config file is required to build the docs Docker image and to publish the site to AWS. If you are building locally only and do not have any AWS credentials for docs.grafana.org then create an empty file named `awsconfig` in the current directory.
```
touch awsconfig
```
Then run (possibly with ``sudo``):
```
make watch
```
This command will not return control of the shell to the user. Instead
the command is now running a new docker container built from the image
we created in the previous step.
Open [localhost:8180](http://localhost:8180) to view the docs.
Open [localhost:3004](http://localhost:3004) to view the docs.
**Note** that after running ``make docs`` you may notice a message
like this in the console output
### Images & Content
> Running at: http://0.0.0.0:8000/
All markdown files are located in this repo (main grafana repo). But all images are added to the https://github.com/grafana/grafana.org repo. So the process of adding images is a bit complicated.
This is misleading. That is **not** the port the documentation is
served from. You must browse to port **8180** to view the new
documentation.
First you need create a feature (PR) branch of https://github.com/grafana/grafana.org so you can make change. Then add the image to the `/static/img/docs` directory. Then make a commit that adds the image.
# Adding a New Page
Adding a new page requires updating the ``mkdocs.yml`` file which is
located in this directory.
For example, if you are adding documentation for a new HTTP API called
``preferences`` you would:
1. Create the file ``docs/sources/http_api/preferences.md``
1. Add a reference to it in ``docs/sources/http_api/overview.md``
1. Update the list under the **pages** key in the ``docs/mkdocs.yml`` file with a reference to your new page:
To be able to use the image your have to quit (CTRL-C) the `make watch` command (that you run in the same directory as this README). Then simply rerun `make watch`, it will restart the docs server but now with access to your image.
### Editing content
Changes to the markdown files should automatically cause a docs rebuild and live reload should reload the page in your browser.
If you have not lost the admin password then it is better to set in the Grafana UI. If you need to set the password in a script then the [Grafana API](http://docs.grafana.org/http_api/user/#change-password) can be used. Here is an example with curl using basic auth:
```bash
curl -X PUT -H "Content-Type: application/json" -d '{
Grafana collects some metrics about it self internally. Currently Grafana supports pushing metrics to graphite and exposing them to be scraped by Prometheus.
To enabled internal metrics you have to enable it under the [metrics] section in your [grafana.ini](http://docs.grafana.org/installation/configuration/#enabled-6) config file.If you want to push metrics to graphite you have also have to configure the [metrics.graphite](http://docs.grafana.org/installation/configuration/#metrics-graphite) section.
> Alerting is only available in Grafana v4.0 and above.
The alert engine publishes some internal metrics about itself. You can read more about how Grafana published [internal metrics](/installation/configuration/#metrics).
Description | Type | Metric name
---------- | ----------- | ----------
Total number of alerts | counter | `alerting.active_alerts`
Alert execution result | counter | `alerting.result`
Notifications sent counter | counter | `alerting.notifications_sent`
"message":"Load is peaking. Make sure the traffic is real and spin up more webfronts",
"evalMatches":[

"metric":"requests",
"tags":{},
"value":122

- **state** - The possible values for alert state are: `ok`, `paused`, `alerting`, `pending`, `no_data`.

In DingTalk PC Client:
1. Click "more" icon on left bottom of the panel.
2. Click "Robot Manage" item in the pop menu, there will be a new panel call "Robot Manage".
3. In the "Robot Manage" panel, select "customised: customised robot with Webhook".
4. In the next new panel named "robot detail", click "Add" button.
5. In "Add Robot" panel, input a nickname for the robot and select a "message group" which the robot will join in. click "next".
6. There will be a Webhook URL in the panel, looks like this: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxx. Copy this URL to the grafana Dingtalk setting page and then click "finish".
Dingtalk supports the following "message type": `text`, `link` and `markdown`. Only the `text` message type is supported.
### Kafka
Notifications can be sent to a Kafka topic from Grafana using [Kafka REST Proxy](https://docs.confluent.io/1.0/kafka-rest/docs/index.html).
There are couple of configurations options which need to be set in Grafana UI under Kafka Settings:
1. Kafka REST Proxy endpoint.
2. Kafka Topic.
Once these two properties are set, you can send the alerts to Kafka for further processing or throttling them.
### Other Supported Notification Channels
Grafana also supports the following Notification Channels:
- HipChat
- VictorOps
- Sensu
- OpsGenie
- Threema
- Pushover
- Telegram
- LINE
# Enable images in notifications {#external-image-store}
Grafan can render the panel associated with the alert rule and include that in the notification. Some types
of notifications require that this image be publicly accessable (Slack for example). In order to support
images in notifications like Slack Grafana can upload the image to an image store. It currently supports
Amazon S3 for this and Webdav. So to set that up you need to configure the
[external image uploader](/installation/configuration/#external-image-storage) in your grafana-server ini
config file.

# Using AWS CloudWatch in Grafana
Grafana ships with built in support for CloudWatch. You just have to add it as a data source and you will
be ready to build dashboards for you CloudWatch metrics.
## Adding the data source
1. Open the side menu by clicking the the Grafana icon in the top header.
2. In the side menu under the `Dashboards` link you should find a link named `Data Sources`.
> NOTE: If this link is missing in the side menu it means that your current user does not have the `Admin` role for the current organization.
3. Click the `Add new` link in the top header.
4. Select `CloudWatch` from the dropdown.
> NOTE: If at any moment you have issues with getting this datasource to work and grafana is giving you undescriptive errors then dont forget to check your log file (try looking in /var/log/grafana/).
Name | Description
------------ | -------------
Name | The data source name, important that this is the same as in Grafana v1.x if you plan to import old dashboards.
Default | Default data source means that it will be pre-selected for new panels.
Credentials profile name | Specify the name of the profile to use (if you use `~/aws/credentials` file), leave blank for default. This option was introduced in Grafana 2.5.1
Default Region | Used in query editor to set region (can be changed on per query basis)
Custom Metrics namespace | Specify the CloudWatch namespace of Custom metrics
Assume Role Arn | Specify the ARN of the role to assume
## Authentication
### IAM Roles
Currently all access to CloudWatch is done server side by the Grafana backend using the official AWS SDK. If you grafana
server is running on AWS you can use IAM Roles and authentication will be handled automatically.
Checkout AWS docs on [IAM Roles](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html)
### AWS credentials file
Create a file at `~/.aws/credentials`. That is the `HOME` path for user running grafana-server.
> NOTE: If you think you have the credentials file in the right place but it is still not working then you might try moving your .aws file to '/usr/share/grafana/' and make sure your credentials file has at most 0644 permissions.
Example content:
[default]
aws_access_key_id = asdsadasdasdasd
aws_secret_access_key = dasdasdsadasdasdasdsa
region = us-west-2
## Metric Query Editor
You need to specify a namespace, metric, at least one stat, and at least one dimension.
## Templated queries
CloudWatch Datasource Plugin provides the following functions in `Variables values query` field in Templating Editor to query `region`, `namespaces`, `metric names` and `dimension keys/values` on the CloudWatch.
Name | Description
------- | --------
`regions()` | Returns a list of regions AWS provides their service.
`namespaces()` | Returns a list of namespaces CloudWatch support.
`metrics(namespace)` | Returns a list of metrics in the namespace.
`dimension_keys(namespace)` | Returns a list of dimension keys in the namespace.
`dimension_values(region, namespace, metric, dimension_key)` | Returns a list of dimension values matching the specified `region`, `namespace`, `metric` and `dimension_key`.
`ebs_volume_ids(region, instance_id)` | Returns a list of volume id matching the specified `region`, `instance_id`.
`ec2_instance_attribute(region, attribute_name, filters)` | Returns a list of attribute matching the specified `region`, `attribute_name`, `filters`.
For details about the metrics CloudWatch provides, please refer to the [CloudWatch documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html).

# Using Elasticsearch in Grafana
Grafana ships with advanced support for Elasticsearch. You can do many types of
simple or complex elasticsearch queries to visualize logs or metrics stored in elasticsearch. You can
also annotate your graphs with log events stored in elasticsearch.
## Adding the data source
1. Open the side menu by clicking the the Grafana icon in the top header.
2. In the side menu under the `Dashboards` link you should find a link named `Data Sources`.
> NOTE: If this link is missing in the side menu it means that your current user does not have the `Admin` role for the current organization.
3. Click the `Add new` link in the top header.
4. Select `Elasticsearch` from the dropdown.
Name | Description
------------ | -------------
Name | The data source name, important that this is the same as in Grafana v1.x if you plan to import old dashboards.
Default | Default data source means that it will be pre-selected for new panels.
Url | The http protocol, ip and port of you elasticsearch server.
Access | Proxy = access via Grafana backend, Direct = access directly from browser.
Proxy access means that the Grafana backend will proxy all requests from the browser, and send them on to the Data Source. This is useful because it can eliminate CORS (Cross Origin Site Resource) issues, as well as eliminate the need to disseminate authentication details to the Data Source to the browser.
Direct access is still supported because in some cases it may be useful to access a Data Source directly depending on the use case and topology of Grafana, the user, and the Data Source.
### Direct access
If you select direct access you must update your Elasticsearch configuration to allow other domains to access
Elasticsearch from the browser. You do this by specifying these to options in your **elasticsearch.yml** config file.
Here you can specify a default for the `time field` and specify the name of your elasticsearch index. You can use
a time pattern for the index name or a wildcard.
## Metric Query editor
The Elasticsearch query editor allows you to select multiple metrics and group by multiple terms or filters. Use the plus and minus icons to the right to add / remove
metrics or group bys. Some metrics and group by have options, click the option text to expand the the row to view and edit metric or group by options.
## Pipeline metrics
If you have Elasticsearch 2.x and Grafana 2.6 or above then you can use pipeline metric aggregations like
**Moving Average** and **Derivative**. Elasticsearch pipeline metrics require another metric to be based on. Use the eye icon next to the metric
to hide metrics from appearing in the graph. This is useful for metrics you only have in the query to be used
