Health checks

    The health checks section allows you to disable certain health checks, and configure your own custom notification methods, that will automatically run the health checks every so often, and notify you if any health checks fails.

    An example of a HealthChecks settings can look something like this:

    "Umbraco": {
      "CMS": {
        "HealthChecks": {
          "DisabledChecks": [
            {
              "Id": "D0F7599E-9B2A-4D9E-9883-81C7EDC5616F"
            }
          ],
          "Notification": {
            "Enabled": true,
            "FirstRunTime": "5 * * * *",
            "Period": "1.00:00:00",
            "NotificationMethods": {
              "email": {
                "Enabled": true,
                "Verbosity": "Detailed",
                "FailureOnly": true,
                "Settings": {
                  "RecipientEmail": "[email protected]"
                }
              }
            }
          }
        }
      }
    }

    This config will disable the macro errors check, and enable notifications to run the checks and notify via email if a check fails. The checks will run the first time five minutes after the site is booted, and then once every day.

    The email notification method is built in, if you want to read more about creating you own notification methods, or see a list of the ID of every built in health check, then see Extending health checks

    But let's go through the config one by one

    Disabled checks

    A list of DisabledHealthCheckSettings objects, each of these objects represents a disabled health check. Only the Id key needs to be present and have a value, corosponding to the GUID of the health check to disable.

    There is also a DisabledOn key representing the date the health check was disabked and a DisabledBy key containing the ID of the user that disabled the health check, however these values are currently not used.

    Notification

    Settings relating to running the health checks automatically and sending out notifications.

    Enabled

    Allows you to disable or enable all notifications methods, if set to false, the health checks will not automatically run.

    First run time

    This will configure when you run the health checks for the first time, if the value is not configured the health checks will run immediately after the site boots for the first time. This value is specified as a string in crontab format, so in this example, the health checks will run 5 minutes after the site is first booted.

    Period

    Specifies how often the health checks should run, as a DateTime string, in this example the checks will run every day (every 24 hours).

    Notification methods

    A dictionary of all the notification methods that should be used.

    The key of the dictionary is the alias of the notification method, and the value is a HealthChecksNotificationMethodSettings configuration object, in this case it's the built in email notification method.

    Each object allows the following to be configured:

    Enabled

    Allows you to enable or disable specific checks.

    Verbosity

    Configures how verbose the reporting should be, the available options are:

    • Summary
    • Detailed

    Failure only

    If set to true, the notification method will only run if a check has failed.

    Settings

    Allows you to set custom settings for a given implementation of a notification method, which settings are available depends on the specific implementation.
