## Add related links to custom dashboards
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/216385) in GitLab 13.1.
You can embed links to other dashboards or external services in your custom
dashboard by adding **Related links** to your dashboard's YAML file. Related links
open in the same tab as the dashboard. Related links can be displayed in the
following locations on your dashboard:
- At the top of your dashboard as the top level [`links` dashboard property](../../../operations/metrics/dashboards/yaml.md#dashboard-top-level-properties).
- In charts context menus as the [`links` property of a panel](../../../operations/metrics/dashboards/yaml.md#panel-panels-properties).
Related links can contain the following attributes:
- `url`: The full URL to the link. Required.
- `title`: A phrase describing the link. Optional. If this attribute is not set,
the full URL is used for the link title.
- `type`: A string declaring the type of link. Optional. If set to `grafana`, the
dashboard's time range values are converted to Grafana's time range format and
appended to the `url`.
The dashboard's time range is appended to the `url` as URL parameters.
The following example shows two related links (`GitLab.com` and `GitLab Documentation`)
added to a dashboard:

## Defining custom dashboards per project
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/59974) in GitLab 12.1.
By default, all projects include a GitLab-defined Prometheus dashboard, which
includes a few key metrics, but you can also define your own custom dashboards.
You may create a new file from scratch or duplicate a GitLab-defined Prometheus
dashboard.
NOTE: **Note:**
The metrics as defined below do not support alerts, unlike
[custom metrics](../index.md#adding-custom-metrics).
### Adding a new dashboard to your project
> UI option [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/223204) in GitLab 13.2.
You can configure a custom dashboard by adding a new YAML file into your project's
`.gitlab/dashboards/` directory. In order for the dashboards to be displayed on
the project's **{cloud-gear}** **Operations > Metrics** page, the files must have a `.yml`
extension and should be present in the project's **default** branch.
To create a new dashboard from the GitLab user interface:
1. Sign in to GitLab as a user with Maintainer or Owner
[permissions](../../../user/permissions.md#project-members-permissions).
1. Navigate to your dashboard at **{cloud-gear}** **Operations > Metrics**.
1. In the top-right corner of your dashboard, click the **{file-addition-solid}** **Actions** menu,
and select **Create new**:
![Monitoring Dashboard actions menu with create new item](../../../user/project/integrations/img/actions_menu_create_new_dashboard_v13_2.png)
1. In the modal window, click **Open Repository**, then follow the instructions
for creating a new dashboard from the command line.
To create a new dashboard from the command line:
1. Create `.gitlab/dashboards/prom_alerts.yml` under your repository's root
directory. Each YAML file should define the layout of the dashboard and the
Prometheus queries used to populate data. This example dashboard displays a
single area chart:
```yaml
dashboard: 'Dashboard Title'
panel_groups:
- group: 'Group Title'
panels:
- type: area-chart
title: "Chart Title"
y_label: "Y-Axis"
y_axis:
format: number
precision: 0
metrics:
- id: my_metric_id
query_range: 'http_requests_total'
label: "Instance: {{instance}}, method: {{method}}"
unit: "count"
```
1. Save the file, commit, and push to your repository. The file must be present in your **default** branch.
1. Navigate to your project's **Operations > Metrics** and choose the custom
dashboard from the dropdown.
NOTE: **Note:**
Configuration files nested under subdirectories of `.gitlab/dashboards` are not
supported and will not be available in the UI.
### Duplicating a GitLab-defined dashboard
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/37238) in GitLab 12.7.
> - From [GitLab 12.8 onwards](https://gitlab.com/gitlab-org/gitlab/-/issues/39505), custom metrics are also duplicated when you duplicate a dashboard.
You can save a complete copy of a GitLab defined dashboard along with all custom metrics added to it.
Resulting `.yml` file can be customized and adapted to your project.
You can decide to save the dashboard `.yml` file in the project's **default** branch or in a
new branch.
1. Click **Duplicate dashboard** in the dashboard dropdown or in the actions menu.
NOTE: **Note:**
You can duplicate only GitLab-defined dashboards.
1. Enter the file name and other information, such as the new commit's message, and click **Duplicate**.
If you select your **default** branch, the new dashboard becomes immediately available.
If you select another branch, this branch should be merged to your **default** branch first.
## Troubleshooting
When troubleshooting issues with a managed Prometheus app, it is often useful to
[view the Prometheus UI](../../../development/prometheus.md#access-the-ui-of-a-prometheus-managed-application-in-kubernetes).
### "No data found" error on Metrics dashboard page
If the "No data found" screen continues to appear, it could be due to:
- No successful deployments have occurred to this environment.
- Prometheus does not have performance data for this environment, or the metrics
are not labeled correctly. To test this, connect to the Prometheus server and
[run a query](../../../user/project/integrations/prometheus_library/kubernetes.md#metrics-supported), replacing `$CI_ENVIRONMENT_SLUG`
with the name of your environment.
- You may need to re-add the GitLab predefined common metrics. This can be done by running the [import common metrics Rake task](../../../administration/raketasks/maintenance.md#import-common-metrics).

Custom metrics can be monitored by adding them on the monitoring dashboard page. Once saved, they will be displayed on the environment performance dashboard provided that either:
- A [connected Kubernetes cluster](../../user/project/clusters/add_remove_clusters.md) with the environment scope of `*` is used and [Prometheus installed on the cluster](../../user/project/integrations/prometheus.md#enabling-prometheus-integration)
- Prometheus is [manually configured](../../user/project/integrations/prometheus.md#manual-configuration-of-prometheus).
![Add New Metric](../../user/project/integrations/img/prometheus_add_metric.png)
A few fields are required:
- **Name**: Chart title
- **Type**: Type of metric. Metrics of the same type will be shown together.
- **Query**: Valid [PromQL query](https://prometheus.io/docs/prometheus/latest/querying/basics/).
- **Y-axis label**: Y axis title to display on the dashboard.
- **Unit label**: Query units, for example `req / sec`. Shown next to the value.
Multiple metrics can be displayed on the same chart if the fields **Name**, **Type**, and **Y-axis label** match between metrics. For example, a metric with **Name** `Requests Rate`, **Type** `Business`, and **Y-axis label** `rec / sec` would display on the same chart as a second metric with the same values. A **Legend label** is suggested if this feature is used.

For managed Prometheus instances using auto configuration, alerts for metrics [can be configured](#adding-custom-metrics) directly in the performance dashboard.
To set an alert:
1. Click on the ellipsis icon in the top right corner of the metric you want to create the alert for.
1. Choose **Alerts**
1. Set threshold and operator.
1. Click **Add** to save and activate the alert.
![Adding an alert](../../user/project/integrations/img/prometheus_alert.png)
To remove the alert, click back on the alert icon for the desired metric, and click **Delete**.
### External Prometheus instances
>- [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/9258) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.8.
>- [Moved](https://gitlab.com/gitlab-org/gitlab/-/issues/42640) to [GitLab Core](https://about.gitlab.com/pricing/) in 12.10.
For manually configured Prometheus servers, a notify endpoint is provided to use with Prometheus webhooks. If you have manual configuration enabled, an **Alerts** section is added to **Settings > Integrations > Prometheus**. This contains the *URL* and *Authorization Key*. The **Reset Key** button will invalidate the key and generate a new one.
![Prometheus service configuration of Alerts](../../user/project/integrations/img/prometheus_service_alerts.png)
To send GitLab alert notifications, copy the *URL* and *Authorization Key* into the [`webhook_configs`](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config) section of your Prometheus Alertmanager configuration:
```yaml
receivers:
name: gitlab
webhook_configs:
- http_config:
bearer_token: 9e1cbfcd546896a9ea8be557caf13a76
send_resolved: true
url: http://192.168.178.31:3001/root/manual_prometheus/prometheus/alerts/notify.json
...
```
In order for GitLab to associate your alerts with an [environment](../../ci/environments/index.md), you need to configure a `gitlab_environment_name` label on the alerts you set up in Prometheus. The value of this should match the name of your Environment in GitLab.
NOTE: **Note**
In GitLab versions 13.1 and greater, you can configure your manually configured Prometheus server to use the [Generic alerts integration](../../user/project/integrations/generic_alerts.md).
## Taking action on incidents **(ULTIMATE)**
>- [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/4925) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.11.
>- [From GitLab Ultimate 12.5](https://gitlab.com/gitlab-org/gitlab/-/issues/13401), when GitLab receives a recovery alert, it will automatically close the associated issue.
Alerts can be used to trigger actions, like opening an issue automatically (disabled by default since `13.1`). To configure the actions:
1. Navigate to your project's **Settings > Operations > Incidents**.
1. Enable the option to create issues.
1. Choose the [issue template](../../user/project/description_templates.md) to create the issue from.
1. Optionally, select whether to send an email notification to the developers of the project.
1. Click **Save changes**.
Once enabled, an issue will be opened automatically when an alert is triggered which contains values extracted from [alert's payload](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config):
- Issue author: `GitLab Alert Bot`
- Issue title: Extract from `annotations/title`, `annotations/summary` or `labels/alertname`
- Alert `Summary`: A list of properties
- `starts_at`: Alert start time via `startsAt`
- `full_query`: Alert query extracted from `generatorURL`
- Optional list of attached annotations extracted from `annotations/*`
- Alert [GFM](../../user/markdown.md): GitLab Flavored Markdown from `annotations/gitlab_incident_markdown`
When GitLab receives a **Recovery Alert**, it will automatically close the associated issue. This action will be recorded as a system message on the issue indicating that it was closed automatically by the GitLab Alert bot.
To further customize the issue, you can add labels, mentions, or any other supported [quick action](../../user/project/quick_actions.md) in the selected issue template, which will apply to all incidents. To limit quick actions or other information to only specific types of alerts, use the `annotations/gitlab_incident_markdown` field.
Since [version 12.2](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/63373), GitLab will tag each incident issue with the `incident` label automatically. If the label does not yet exist, it will be created automatically as well.
If the metric exceeds the threshold of the alert for over 5 minutes, an email will be sent to all [Maintainers and Owners](../../user/permissions.md#project-members-permissions) of the project.

- Prometheus is [manually configured](#manual-configuration-of-prometheus).
![Add New Metric](img/prometheus_add_metric.png)
A few fields are required:
- **Name**: Chart title
- **Type**: Type of metric. Metrics of the same type will be shown together.
- **Query**: Valid [PromQL query](https://prometheus.io/docs/prometheus/latest/querying/basics/).
- **Y-axis label**: Y axis title to display on the dashboard.
- **Unit label**: Query units, for example `req / sec`. Shown next to the value.
Multiple metrics can be displayed on the same chart if the fields **Name**, **Type**, and **Y-axis label** match between metrics. For example, a metric with **Name** `Requests Rate`, **Type** `Business`, and **Y-axis label** `rec / sec` would display on the same chart as a second metric with the same values. A **Legend label** is suggested if this feature is used.
#### Editing additional metrics from the dashboard
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/208976) in GitLab 12.9.
You can edit existing additional custom metrics by clicking the **{ellipsis_v}** **More actions** dropdown and selecting **Edit metric**.
![Edit metric](img/prometheus_dashboard_edit_metric_link_v_12_9.png)
### Defining custom dashboards per project
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/59974) in GitLab 12.1.
By default, all projects include a GitLab-defined Prometheus dashboard, which
includes a few key metrics, but you can also define your own custom dashboards.
You may create a new file from scratch or duplicate a GitLab-defined Prometheus
dashboard.
NOTE: **Note:**
The metrics as defined below do not support alerts, unlike
[custom metrics](#adding-custom-metrics).
#### Adding a new dashboard to your project
> UI option [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/223204) in GitLab 13.2.
You can configure a custom dashboard by adding a new YAML file into your project's
`.gitlab/dashboards/` directory. In order for the dashboards to be displayed on
the project's **{cloud-gear}** **Operations > Metrics** page, the files must have a `.yml`
extension and should be present in the project's **default** branch.
To create a new dashboard from the GitLab user interface:
1. Sign in to GitLab as a user with Maintainer or Owner
[permissions](../../permissions.md#project-members-permissions).
1. Navigate to your dashboard at **{cloud-gear}** **Operations > Metrics**.
1. In the top-right corner of your dashboard, click the **{file-addition-solid}** **Actions** menu,
and select **Create new**:
![Monitoring Dashboard actions menu with create new item](img/actions_menu_create_new_dashboard_v13_2.png)
1. In the modal window, click **Open Repository**, then follow the instructions
for creating a new dashboard from the command line.
To create a new dashboard from the command line:
1. Create `.gitlab/dashboards/prom_alerts.yml` under your repository's root
directory. Each YAML file should define the layout of the dashboard and the
Prometheus queries used to populate data. This example dashboard displays a
single area chart:
```yaml
dashboard: 'Dashboard Title'
panel_groups:
- group: 'Group Title'
panels:
- type: area-chart
title: "Chart Title"
y_label: "Y-Axis"
y_axis:
format: number
precision: 0
metrics:
- id: my_metric_id
query_range: 'http_requests_total'
label: "Instance: {{instance}}, method: {{method}}"
unit: "count"
```
1. Save the file, commit, and push to your repository. The file must be present in your **default** branch.
1. Navigate to your project's **Operations > Metrics** and choose the custom
dashboard from the dropdown.
NOTE: **Note:**
Configuration files nested under subdirectories of `.gitlab/dashboards` are not
supported and will not be available in the UI.
#### Duplicating a GitLab-defined dashboard
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/37238) in GitLab 12.7.
> - From [GitLab 12.8 onwards](https://gitlab.com/gitlab-org/gitlab/-/issues/39505), custom metrics are also duplicated when you duplicate a dashboard.
You can save a complete copy of a GitLab defined dashboard along with all custom metrics added to it.
Resulting `.yml` file can be customized and adapted to your project.
You can decide to save the dashboard `.yml` file in the project's **default** branch or in a
new branch.
1. Click **Duplicate dashboard** in the dashboard dropdown or in the actions menu.
NOTE: **Note:**
You can duplicate only GitLab-defined dashboards.
1. Enter the file name and other information, such as the new commit's message, and click **Duplicate**.
If you select your **default** branch, the new dashboard becomes immediately available.
If you select another branch, this branch should be merged to your **default** branch first.
#### Dashboard YAML syntax validation
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/33202) in GitLab 13.1.
To confirm your dashboard definition contains valid YAML syntax:
1. Navigate to **{doc-text}** **Repository > Files**.
1. Navigate to your dashboard file in your repository.
1. Review the information pane about the file, displayed above the file contents.
Files with valid syntax display **Metrics Dashboard YAML definition is valid**,
and files with invalid syntax display **Metrics Dashboard YAML definition is invalid**.
![Metrics Dashboard_YAML_syntax_validation](img/prometheus_dashboard_yaml_validation_v13_1.png)
When **Metrics Dashboard YAML definition is invalid** at least one of the following messages is displayed:
1. `dashboard: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#dashboard-top-level-properties)
1. `panel_groups: should be an array of panel_groups objects` [learn more](../../../operations/metrics/dashboards/yaml.md#dashboard-top-level-properties)
1. `group: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#panel-group-panel_groups-properties)
1. `panels: should be an array of panels objects` [learn more](../../../operations/metrics/dashboards/yaml.md#panel-group-panel_groups-properties)
1. `title: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#panel-panels-properties)
1. `metrics: should be an array of metrics objects` [learn more](../../../operations/metrics/dashboards/yaml.md#panel-panels-properties)
1. `query: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#metrics-metrics-properties)
1. `query_range: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#metrics-metrics-properties)
1. `unit: can't be blank` [learn more](../../../operations/metrics/dashboards/yaml.md#metrics-metrics-properties)
1. `YAML syntax: The parsed YAML is too big`
This is displayed when the YAML file is larger than 1 MB.
1. `YAML syntax: Invalid configuration format`
This is displayed when the YAML file is empty or does not contain valid YAML.
Metrics Dashboard YAML definition validation information is also available as a [GraphQL API field](../../../api/graphql/reference/index.md#metricsdashboard)
### Add related links to custom dashboards
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/216385) in GitLab 13.1.
You can embed links to other dashboards or external services in your custom
dashboard by adding **Related links** to your dashboard's YAML file. Related links
open in the same tab as the dashboard. Related links can be displayed in the
following locations on your dashboard:
- At the top of your dashboard as the top level [`links` dashboard property](../../../operations/metrics/dashboards/yaml.md#dashboard-top-level-properties).
- In charts context menus as the [`links` property of a panel](../../../operations/metrics/dashboards/yaml.md#panel-panels-properties).
Related links can contain the following attributes:
- `url`: The full URL to the link. Required.
- `title`: A phrase describing the link. Optional. If this attribute is not set,
the full URL is used for the link title.
- `type`: A string declaring the type of link. Optional. If set to `grafana`, the
dashboard's time range values are converted to Grafana's time range format and
appended to the `url`.
The dashboard's time range is appended to the `url` as URL parameters.
The following example shows two related links (`GitLab.com` and `GitLab Documentation`)
added to a dashboard:
![Links UI](img/related_links_v13_1.png)
#### Links Syntax
```yaml
links:
- title: GitLab.com
url: https://gitlab.com
- title: GitLab Documentation
url: https://docs.gitlab.com
- title: Public Grafana playground dashboard
url: https://play.grafana.org/d/000000012/grafana-play-home?orgId=1
type: grafana
```
### Setting up alerts for Prometheus metrics
#### Managed Prometheus instances
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/6590) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.2 for [custom metrics](#adding-custom-metrics), and 11.3 for [library metrics](prometheus_library/metrics.md).
For managed Prometheus instances using auto configuration, alerts for metrics [can be configured](#adding-custom-metrics) directly in the performance dashboard.
To set an alert:
1. Click on the ellipsis icon in the top right corner of the metric you want to create the alert for.
1. Choose **Alerts**
1. Set threshold and operator.
1. Click **Add** to save and activate the alert.
![Adding an alert](img/prometheus_alert.png)
To remove the alert, click back on the alert icon for the desired metric, and click **Delete**.
#### External Prometheus instances
>- [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/9258) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.8.
>- [Moved](https://gitlab.com/gitlab-org/gitlab/-/issues/42640) to [GitLab Core](https://about.gitlab.com/pricing/) in 12.10.
For manually configured Prometheus servers, a notify endpoint is provided to use with Prometheus webhooks. If you have manual configuration enabled, an **Alerts** section is added to **Settings > Integrations > Prometheus**. This contains the *URL* and *Authorization Key*. The **Reset Key** button will invalidate the key and generate a new one.
![Prometheus service configuration of Alerts](img/prometheus_service_alerts.png)
To send GitLab alert notifications, copy the *URL* and *Authorization Key* into the [`webhook_configs`](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config) section of your Prometheus Alertmanager configuration:
```yaml
receivers:
name: gitlab
webhook_configs:
- http_config:
bearer_token: 9e1cbfcd546896a9ea8be557caf13a76
send_resolved: true
url: http://192.168.178.31:3001/root/manual_prometheus/prometheus/alerts/notify.json
...
```
In order for GitLab to associate your alerts with an [environment](../../../ci/environments/index.md), you need to configure a `gitlab_environment_name` label on the alerts you set up in Prometheus. The value of this should match the name of your Environment in GitLab.
NOTE: **Note**
In GitLab versions 13.1 and greater, you can configure your manually configured Prometheus server to use the [Generic alerts integration](generic_alerts.md).
### Taking action on incidents **(ULTIMATE)**
>- [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/4925) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.11.
>- [From GitLab Ultimate 12.5](https://gitlab.com/gitlab-org/gitlab/-/issues/13401), when GitLab receives a recovery alert, it will automatically close the associated issue.
Alerts can be used to trigger actions, like opening an issue automatically (disabled by default since `13.1`). To configure the actions:
1. Navigate to your project's **Settings > Operations > Incidents**.
1. Enable the option to create issues.
1. Choose the [issue template](../description_templates.md) to create the issue from.
1. Optionally, select whether to send an email notification to the developers of the project.
1. Click **Save changes**.
Once enabled, an issue will be opened automatically when an alert is triggered which contains values extracted from [alert's payload](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config):
- Issue author: `GitLab Alert Bot`
- Issue title: Extract from `annotations/title`, `annotations/summary` or `labels/alertname`
- Alert `Summary`: A list of properties
- `starts_at`: Alert start time via `startsAt`
- `full_query`: Alert query extracted from `generatorURL`
- Optional list of attached annotations extracted from `annotations/*`
- Alert [GFM](../../markdown.md): GitLab Flavored Markdown from `annotations/gitlab_incident_markdown`
When GitLab receives a **Recovery Alert**, it will automatically close the associated issue. This action will be recorded as a system message on the issue indicating that it was closed automatically by the GitLab Alert bot.
To further customize the issue, you can add labels, mentions, or any other supported [quick action](../quick_actions.md) in the selected issue template, which will apply to all incidents. To limit quick actions or other information to only specific types of alerts, use the `annotations/gitlab_incident_markdown` field.
Since [version 12.2](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/63373), GitLab will tag each incident issue with the `incident` label automatically. If the label does not yet exist, it will be created automatically as well.
If the metric exceeds the threshold of the alert for over 5 minutes, an email will be sent to all [Maintainers and Owners](../../permissions.md#project-members-permissions) of the project.

## Troubleshooting
When troubleshooting issues with a managed Prometheus app, it is often useful to
[view the Prometheus UI](../../../development/prometheus.md#access-the-ui-of-a-prometheus-managed-application-in-kubernetes).
### "No data found" error on Metrics dashboard page
If the "No data found" screen continues to appear, it could be due to:
- No successful deployments have occurred to this environment.
- Prometheus does not have performance data for this environment, or the metrics
are not labeled correctly. To test this, connect to the Prometheus server and
[run a query](prometheus_library/kubernetes.md#metrics-supported), replacing `$CI_ENVIRONMENT_SLUG`
with the name of your environment.
- You may need to re-add the GitLab predefined common metrics. This can be done by running the [import common metrics Rake task](../../../administration/raketasks/maintenance.md#import-common-metrics).
