Error tracking allows developers to easily discover and view the errors that their application may be generating. By surfacing error information where the code is being developed, efficiency and awareness can be increased.
## Sentry error tracking
[Sentry](https://sentry.io/) is an open source error tracking system. GitLab allows administrators to connect Sentry to GitLab, to allow users to view a list of Sentry errors in GitLab itself.
### Deploying Sentry
You may sign up to the cloud hosted https://sentry.io or deploy your own [on-premise instance](https://docs.sentry.io/server/installation/).
### Enabling Sentry
GitLab provides an easy way to connect Sentry to your project:
1. Sign up to Sentry.io or [deploy your own](#deploying-sentry) Sentry instance.
1. [Find or generate](https://docs.sentry.io/api/auth/) a Sentry auth token for your Sentry project.
1. Navigate to your project’s **Settings > Operations** and provide the Sentry API URL and auth token.
1. Ensure that the 'Active' checkbox is set.
1. Click **Save changes** for the changes to take effect.
1. You can now visit **Operations > Error Tracking** in your project's sidebar to [view a list](#error-tracking-list) of Sentry errors.
## Error Tracking List
The Error Tracking list may be found at **Operations > Error Tracking** in your project's sidebar.
