+# Set up alerts for Prometheus metrics
+
+After [configuring metrics for your CI/CD environment](index.md), you can set up
+alerting for Prometheus metrics depending on the location of your instances, and
+[trigger actions from alerts](#trigger-actions-from-alerts-ultimate) to notify
+your team when environment performance falls outside of the boundaries you set.

+## 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](index.md#adding-custom-metrics), and 11.3 for [library metrics](../../user/project/integrations/prometheus_library/metrics.md).
+
+For managed Prometheus instances using auto configuration, you can
+[configure alerts for metrics](index.md#adding-custom-metrics) directly in the
+[metrics dashboard](index.md). To set an alert:
+
+1. In your project, navigate to **{cloud-gear}** **Operations > Metrics**,
+1. Identify the metric you want to create the alert for, and click the
+   **ellipsis** **{ellipsis_v}** icon in the top right corner of the metric.
+1. Choose **Alerts**.
+1. Set threshold and operator.
+1. Click **Add** to save and activate the alert.

+>- [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, GitLab provides a notify endpoint for
+use with Prometheus webhooks. If you have manual configuration enabled, an
+**Alerts** section is added to **{settings}** **Settings > Integrations > Prometheus**.
+This section contains the **URL** and **Authorization Key** you will need. 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

+      url: http://192.168.178.31:3001/root/manual_prometheus/prometheus/alerts/notify.json
+  ...
+```
+
+For GitLab to associate your alerts with an [environment](../../ci/environments/index.md),
+you must 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).

+## Trigger actions from alerts **(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}** **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**.
+
+After enabling, GitLab automatically opens an issue when an alert is triggered containing
+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 closes the associated issue.
+This action is 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 applies 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 tags each incident issue with the `incident` label automatically. If the label
+does not yet exist, it is also created automatically.
+
+If the metric exceeds the threshold of the alert for over 5 minutes, GitLab sends
+an email to all [Maintainers and Owners](../../user/permissions.md#project-members-permissions)
+of the project.

 Prometheus is deployed into the `gitlab-managed-apps` namespace, using the [official Helm chart](https://github.com/helm/charts/tree/master/stable/prometheus).
