Checking health of sources

Checking the health of a source is done by SourceHealthCheck classes configured in the monitor.source_health_checks key of the backup-server config file.

The package ships with these two checks configured by default:

• MaximumStorageInMB: this check will fail if the total size of your backups is greater than the specified amount of megabytes. You can override the the maximum amount of megabytes in the config file by filling the healthy_maximum_storage_in_mb attribute on a Destination. You can override that value defined on a Destination by settings the healthy_maximum_storage_in_mb on a source.
• MaximumAgeInDays: this check will fail if the age of the youngest back is older than the given amount of days. You can override the the agi in the days in the config file by filling the healthy_maximum_backup_age_in_days attribute on a Destination. You can override that value defined on a Destination by settings the healthy_maximum_backup_age_in_days on a source.

##Creating health checks of your own

In the monitor.source_health_checks key of the backup-server config file you can add health check classes of your own. Any class you add there should extend Spatie\BackupServer\Tasks\Monitor\HealthChecks\Source\SourceHealthCheck. Here is how that abstract class is defined.

namespace Spatie\BackupServer\Tasks\Monitor\HealthChecks\Source;

use Spatie\BackupServer\Models\Source;
use Spatie\BackupServer\Tasks\Monitor\HealthCheckResult;
use Spatie\BackupServer\Tasks\Monitor\HealthChecks\HealthCheck;

abstract class SourceHealthCheck extends HealthCheck
{
    abstract public function getResult(Source $source): HealthCheckResult;
}

##Get notifications of (un)healthy sources
