Creating your custom health check

You can create your own custom health check by letting a class extend Spatie\Backup\Tasks\Monitor\HealthCheck.

That base class contains one abstract method that you should implement.

public function checkHealth(BackupDestination $backupDestination);

If your check determines that the backup is not healthy it should throw a Spatie\Backup\Exceptions\InvalidHealthCheck exception. The HealthCheck base class contains three helpful methods that helps you do this.

• fail($message): will throw the right exception under the hood.
• failIf(bool $condition, string $message): will throw the right exception if $condition is true
• failUnless(bool $condition, string $message): will throw the right exception if $condition is false

You should register your custom health check in the health_checks key of the backup.php config file.

To see an example of a HealthCheck, go read the could of the MaximumAgeInDays and MaximumStorageInMegabytes health checks that are provided by the package.
