# Grafana Configuration
[Grafana](http://grafana.org/) is a tool that allows you to visualize time
series metrics through graphs and dashboards. It supports several backend
data stores, including InfluxDB. GitLab writes performance data to InfluxDB
and Grafana will allow you to query InfluxDB to display useful graphs.
For the easiest installation and configuration, install Grafana on the same
server as InfluxDB. For larger installations, you may want to split out these
services.
## Installation
Grafana supplies package repositories (Yum/Apt) for easy installation.
See [Grafana installation documentation](http://docs.grafana.org/installation/)
for detailed steps.
> **Note**: Before starting Grafana for the first time, set the admin user
and password in `/etc/grafana/grafana.ini`. Otherwise, the default password
will be `admin`.
## Configuration
Login as the admin user. Expand the menu by clicking the Grafana logo in the
top left corner. Choose 'Data Sources' from the menu. Then, click 'Add new'
in the top bar.

Fill in the configuration details for the InfluxDB data source. Save and
Test Connection to ensure the configuration is correct.
- **Name**: InfluxDB
- **Default**: Checked
- **Type**: InfluxDB 0.9.x (Even if you're using InfluxDB 0.10.x)
- **Url**: https://localhost:8086 (Or the remote URL if you've installed InfluxDB
on a separate server)
- **Access**: proxy
- **Database**: gitlab
- **User**: admin (Or the username configured when setting up InfluxDB)
- **Password**: The password configured when you set up InfluxDB

## Apply retention policies and create continuous queries
If you intend to import the GitLab provided Grafana dashboards, you will need
to copy and run a set of queries against InfluxDB to create the needed data
sets.
On the InfluxDB server, run the following command, substituting your InfluxDB
user and password:
```bash
influxdb --username admin -password super_secret
```
This will drop you in to an InfluxDB interactive session. Copy the entire
contents below and paste it in to the interactive session:

## Import Dashboards
You can now import a set of default dashboards that will give you a good
start on displaying useful information. GitLab has published a set of default
[Grafana dashboards][grafana-dashboards] to get you started. Clone the
repository or download a zip/tarball, then follow these steps to import each
JSON file.
Open the dashboard dropdown menu and click 'Import'
![Grafana dashboard dropdown](/img/grafana_dashboard_dropdown.png)
Click 'Choose file' and browse to the location where you downloaded or cloned
the dashboard repository. Pick one of the JSON files to import.
![Grafana dashboard import](/img/grafana_dashboard_import.png)
Once the dashboard is imported, be sure to click save icon in the top bar. If
you do not save the dashboard after importing it will be removed when you
navigate away.
![Grafana save icon](/img/grafana_save_icon.png)
Repeat this process for each dashboard you wish to import.
