Specify a single check by including the `uuid` field or show the total 'up' and 'down' for all checks by leaving off the `uuid` field. To use the Health Checks widget, you first need to generate an API key. 1. In your project, go to project Settings on the navigation bar. 2. Click on API key (read-only) and then click _Create_. 3. Copy the API key that is generated for you. Allowed fields: `["status", "last_ping"]` for single checks, `["up", "down"]` for total stats. ```yaml widget: type: healthchecks url: http://healthchecks.host.or.ip:port key: uuid: # optional, if not included total statistics for all checks is shown ```
