Sentry provides application monitoring. You can use Sentry to drive insights into values such as:

  • Issues


In order to connect Cortex to your Sentry instance, you’ll need to create a Sentry Auth Token, and add it under Settings → Sentry.


If you do not see the Settings page you're looking for in the sidebar, you likely don't have the proper permissions and need to contact your admin.



By default, Cortex will use the entity tag (e.g. my-service) as the "best guess" for the Sentry project name. For example, if your entity tag is my-service, then the corresponding project name in Sentry should also be my-service.

If your Sentry project names don’t cleanly match the Cortex entity tag, you can override this in the Cortex Catalog Descriptor.

Catalog Descriptor

If you need to override the automatic discovery, you can define the following block in your Cortex Catalog Descriptor.

project: my-project # projectName in Sentry

The value for project should be the project name as defined in Sentry.
