# Grafana support for Prometheus
[Grafana](http://grafana.org/) supports querying Prometheus.
The Grafana data source for Prometheus is included since Grafana 2.5.0 (2015-10-28).

The following shows an example Grafana dashboard which queries Prometheus for data:

## Installing
For the full Grafana installation instructions, see the [official Grafana
documentation](http://docs.grafana.org/installation/).

As an example, on Linux, installing Grafana could look like this:

```bash-lang
# Download and unpack Grafana from binary tar (adjust version as appropriate).
curl -L -O https://grafanarel.s3.amazonaws.com/builds/grafana-2.5.0.linux-x64.tar.gz
tar zxf grafana-2.5.0.linux-x64.tar.gz

# Start Grafana.
cd grafana-2.5.0/
./bin/grafana-server web
```

## Using
By default, Grafana will be listening on
[http://localhost:3000](http://localhost:3000). The default login is "admin" /
"admin".

### Creating a Prometheus data source
To create a Prometheus data source:

1. Click on the Grafana logo to open the sidebar menu.
2. Click on "Data Sources" in the sidebar.
3. Click on "Add New".
4. Select "Prometheus" as the type.
5. Set the appropriate Prometheus server URL (for example, `http://localhost:9090/`)
6. Adjust other data source settings as desired (for example, turning the proxy access off).
7. Click "Add" to save the new data source.

The following shows an example data source configuration:

### Creating a Prometheus graph
Follow the standard way of adding a new Grafana graph. Then:

1. Click the graph title, then click "Edit".
2. Under the "Metrics" tab, select your Prometheus data source (bottom right).
3. Enter any Prometheus expression into the "Query" field, while using the "Metric" field to lookup metrics via autocompletion.
4. To format the legend names of time series, use the "Legend format" input in a
similar way to PromDash. For example, to show only the `method` and `status`
labels of a returned query result, separated by a dash, you could use the
legend format string `{{method}} - {{status}}`.
5. Tune other graph settings until you have a working graph.

The following shows an example Prometheus graph configuration:

### Importing pre-built dashboards from Grafana.net
Grafana.net maintains [a collection of shared dashboards](https://grafana.net/dashboards)
which can be downloaded and used with standalone instances of Grafana.  Use
the Grafana.net "Filter" option to browse dashboards for the "Prometheus"
data source only.

You must currently manually edit the downloaded JSON files and correct the
`datasource:` entries to reflect the Grafana data source name which you
chose for your Prometheus server.  Use the "Dashboards" → "Home" → "Import"
option to import the edited dashboard file into your Grafana install.
