# Using Graphite in Grafana

Grafana has an advanced Graphite query editor that lets you quickly navigate the metric space, add functions,
change function parameters and much more. The editor can handle all types of graphite queries. It can even handle complex nested
queries through the use of query references.

## Adding the data source

1. Open the side menu by clicking the Grafana icon in the top header.
2. In the side menu under the `Configuration` link you should find a link named `Data Sources`.
3. Click the `+ Add data source` button in the top header.
4. Select `Graphite` from the *Type* dropdown.

> NOTE: If you're not seeing the `Data Sources` link in your side menu it means that your current user does not have the `Admin` role for the current organization.

Name | Description
------------ | -------------
*Name* | The data source name. This is how you refer to the data source in panels and queries.
*Default* | Default data source means that it will be pre-selected for new panels.
*Url* | The HTTP protocol, IP, and port of your graphite-web or graphite-api install.
*Access* | Server (default) = URL needs to be accessible from the Grafana backend/server, Browser = URL needs to be accessible from the browser.

Access mode controls how requests to the data source will be handled. Server should be the preferred way if nothing else stated.

### Server access mode (Default)

All requests will be made from the browser to Grafana backend/server which in turn will forward the requests to the data source and by that circumvent possible Cross-Origin Resource Sharing (CORS) requirements. The URL needs to be accessible from the grafana backend/server if you select this access mode.

### Browser access mode

All requests will be made from the browser directly to the data source and may be subject to Cross-Origin Resource Sharing (CORS) requirements. The URL needs to be accessible from the browser if you select this access mode.

## Metric editor

### Navigate metric segments

Click the ``Select metric`` link to start navigating the metric space. Once you start you can continue using the mouse
or keyboard arrow keys. You can select a wildcard and still continue.

### Functions

Click the plus icon to the right to add a function. You can search for the function or select it from the menu. Once
a function is selected it will be added and your focus will be in the text box of the first parameter. To later change
a parameter just click on it and it will turn into a text box. To delete a function click the function name followed
by the x icon.

### Optional parameters

Some functions like aliasByNode support an optional second argument. To add this parameter specify for example 3,-2 as the first parameter and the function editor will adapt and move the -2 to a second parameter. To remove the second optional parameter just click on it and leave it blank and the editor will remove it.

### Nested Queries

You can reference queries by the row “letter” that they’re on (similar to  Microsoft Excel). If you add a second query to a graph, you can reference the first query simply by typing in #A. This provides an easy and convenient way to build compounded queries.

## Point consolidation

All Graphite metrics are consolidated so that Graphite doesn't return more data points than there are pixels in the graph. By default,
this consolidation is done using `avg` function. You can control how Graphite consolidates metrics by adding the Graphite consolidateBy function.

> *Notice* This means that legend summary values (max, min, total) cannot be all correct at the same time. They are calculated
> client side by Grafana. And depending on your consolidation function only one or two can be correct at the same time.

## Templating

Instead of hard-coding things like server, application and sensor name in your metric queries you can use variables in their place.
Variables are shown as dropdown select boxes at the top of the dashboard. These dropdowns make it easy to change the data
being displayed in your dashboard.

Check out the [Templating]({{< relref "../../variables/templates-and-variables.md" >}}) documentation for an introduction to the templating feature and the different
types of template variables.

Graphite 1.1 introduced tags and Grafana added support for Graphite queries with tags in version 5.0. To create a variable using tag values, then you need to use the Grafana functions `tags` and `tag_values`.

Query | Description
------------ | -------------
*tags()* | Returns all tags.
*tags(server=~backend\*)* | Returns only tags that occur in series matching the filter expression.
*tag_values(server)*  | Return tag values for the specified tag.
*tag_values(server, server=~backend\*)*  | Returns filtered tag values that occur for the specified tag in series matching those expressions.
*tag_values(server, server=~backend\*, app=~${apps:regex})* | Multiple filter expressions and expressions can contain other variables.

For more details, see the [Graphite docs on the autocomplete api for tags](http://graphite.readthedocs.io/en/latest/tags.html#auto-complete-support).

### Query variable

The query you specify in the query field should be a metric find type of query. For example, a query like `prod.servers.*` will fill the
variable with all possible values that exist in the wildcard position.

You can also create nested variables that use other variables in their definition. For example
`apps.$app.servers.*` uses the variable `$app` in its query definition.

#### Using `__searchFilter` to filter results in Query Variable
> Available from Grafana 6.5 and above

Using `__searchFilter` in the query field will filter the query result based on what the user types in the dropdown select box.
When nothing has been entered by the user the default value for `__searchFilter` is `*` and `` when used as part of a regular expression.

The example below shows how to use `__searchFilter` as part of the query field to enable searching for `server` while the user types in the dropdown select box.

Query
```bash
apps.$app.servers.$__searchFilter
```

TagValues
```bash
tag_values(server, server=~${__searchFilter:regex})
```

### Variable Usage

You can use a variable in a metric node path or as a parameter to a function.
![variable](/img/docs/v2/templated_variable_parameter.png)

There are two syntaxes:

- `$<varname>`  Example: apps.frontend.$server.requests.count
- `[[varname]]` Example: apps.frontend.[[server]].requests.count

Why two ways? The first syntax is easier to read and write but does not allow you to use a variable in the middle of a word. Use
the second syntax in expressions like  `my.server[[serverNumber]].count`.

Example:
[Graphite Templated Dashboard](https://play.grafana.org/dashboard/db/graphite-templated-nested)

### Variable Usage in Tag Queries

Multi-value variables in tag queries use the advanced formatting syntax introduced in Grafana 5.0 for variables: `{var:regex}`. Non-tag queries will use the default glob formatting for multi-value variables.

Example of a tag expression with regex formatting and using the Equal Tilde operator, `=~`:

```text
server=~${servers:regex}
```

Check out the [Advanced Formatting Options section in the Variables]({{< relref "../../variables/templates-and-variables.md#advanced-formatting-options" >}}) documentation for examples and details.

## Annotations

[Annotations]({{< relref "../../reference/annotations.md" >}}) allow you to overlay rich event information on top of graphs. You add annotation
queries via the Dashboard menu / Annotations view.

Graphite supports two ways to query annotations. A regular metric query, for this you use the `Graphite query` textbox. A Graphite events query, use the `Graphite event tags` textbox,
specify a tag or wildcard (leave empty should also work)

## Getting Grafana metrics into Graphite

Grafana exposes metrics for Graphite on the `/metrics` endpoint. For detailed instructions, refer to [Internal Grafana metrics]({{< relref "../../administration/metrics.md">}}).

## Configure the data source with provisioning

It's now possible to configure data sources using config files with Grafana's provisioning system. You can read more about how it works and all the settings you can set for data sources on the [provisioning docs page]({{< relref "../../administration/provisioning/#datasources" >}})

Here are some provisioning examples for this data source.

```yaml
apiVersion: 1

datasources:
  - name: Graphite
    type: graphite
    access: proxy
    url: http://localhost:8080
    jsonData:
      graphiteVersion: "1.1"
```
