Follow these instructions to access Grafana directly (instead of going through the Sourcegraph Site Admin Monitoring page as usual).
Navigate to the Grafana /login URL (e.g., http://localhost:3070/-/debug/grafana/login or append /login to your Grafana direct access URL if different). If you are doing this for the first time, user the username and password admin and admin.
In the left sidebar, click the bell icon 🔔 and select Notification channels.
Click New channel and then specify the settings of your channel. The Type field selects the type of external service (e.g., PagerDuty, Slack, Email). Some service types will require additional configuration in the service itself. Here are some examples:
