> - [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/32351) in GitLab 12.7, behind a disabled feature flag (`self_monitoring_project`).
> - The feature flag was removed and the Self Monitoring Project was [made generally available](https://gitlab.com/gitlab-org/gitlab/issues/198511) in GitLab 12.8.
1. Navigate to **Admin Area > Settings > Metrics and profiling**, and expand the **Self monitoring** section.
1. Toggle the **Create Project** button off.
1. In the confirmation dialog that opens, click **Delete project**.
It can take a few seconds for it to be deleted.
1. After the project is deleted, GitLab displays a message confirming your action.
## Connection to Prometheus
The project will be automatically configured to connect to the
[internal Prometheus](../prometheus/index.md) instance if the Prometheus
instance is present (should be the case if GitLab was installed via Omnibus
and you haven't disabled it).
If that's not the case or if you have an external Prometheus instance or an HA setup,
you should
[configure it manually](../../../user/project/integrations/prometheus.md#manual-configuration-of-prometheus).
## Taking action on Prometheus alerts **(ULTIMATE)**
You can [add a webhook](../../../user/project/integrations/prometheus.md#external-prometheus-instances)
to the Prometheus config in order for GitLab to receive notifications of any alerts.
Once the webhook is setup, you can
[take action on incoming alerts](../../../user/project/integrations/prometheus.md#taking-action-on-incidents-ultimate).
## Adding custom metrics to the self monitoring project
You can add custom metrics in the self monitoring project by:
1. [Duplicating](../../../user/project/integrations/prometheus.md#duplicating-a-gitlab-defined-dashboard) the default dashboard.
1. [Editing](../../../user/project/integrations/prometheus.md#view-and-edit-the-source-file-of-a-custom-dashboard) the newly created dashboard file and configuring it with [dashboard YAML properties](../../../user/project/integrations/prometheus.md#dashboard-yaml-properties).
