### Setting up alerts for Prometheus metrics **(ULTIMATE)**
|
||||
### Defining Dashboards for Prometheus Metrics per Project
|
||||
|
||||
All projects include a GitLab-defined system dashboard, which includes a few key metrics. Optionally, additional dashboards can also be defined by including configuration files in the project repository under `.gitlab/dashboards`. Configuration files nested under subdirectories will not be available in the UI. Each file should define the layout of the dashboard and the prometheus queries used to populate data. Dashboards can be selected from the dropdown in the UI.
|
||||
|
||||
#### Relationship to Custom Metrics
|
||||
|
||||
[Custom Metrics](#adding-additional-metrics-premium) are defined through the UI and, at this point, are unique from metrics defined in dashboard configuration files. Custom Metrics will appear on the system dashboard, as well as support alerting, whereas metrics defined in configuration files do not yet support alerts.
|
||||
|
||||
#### Dashboard Configuration
|
||||
|
||||
Dashboards have several components. A dashboard has many panel groups, which are comprised of panels, which support one or more metrics. The dashboard should be saved with the `.yml` extension.
|
||||
|
||||
Sample YML Configuration
|
||||
```
|
||||
dashboard: 'Dashboard Title'
|
||||
priority: 2
|
||||
panel_groups:
|
||||
- group: 'Group Title'
|
||||
panels:
|
||||
- type: area-chart
|
||||
title: "Chart Title"
|
||||
y_label: "Y-Axis"
|
||||
metrics:
|
||||
- id: metric_of_ages
|
||||
query_range: 'http_requests_total'
|
||||
label: "Metric of Ages"
|
||||
unit: "count"
|
||||
```
|
||||
|
||||
The above sample dashboard would display a single area chart. The following sections outline the details of expected properties.
