Set Up Crons

Sentry Crons allows you to monitor the uptime and performance of any scheduled, recurring job. Once implemented, it'll allow you to get alerts and metrics to help you solve errors, detect timeouts, and prevent disruptions to your service.

Check-in monitoring allows you to track a job's progress by completing two check-ins: one at the start of your job and another at the end of your job. This two-step process allows Sentry to notify you if your job didn't start when expected (missed) or if it exceeded its maximum runtime (failed).

Copied
// 🟡 Notify Sentry your job is running:
$checkInId = \Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::inProgress()
);

// Execute your scheduled task here...

// 🟢 Notify Sentry your job has completed successfully:
\Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::ok(),
    checkInId: $checkInId,
);

If your job execution fails, you can notify Sentry about the failure:

Copied
// 🔴 Notify Sentry your job has failed:
\Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::error()
    checkInId: $checkInId,
);

Alternatively, you can use withMonitor() to monitor a callback.

Copied
\Sentry\withMonitor(
    slug: '<monitor-slug>',
    callback: fn () => doSomething(),
);

This will create an in-progress check-in and either an ok or error check-in, depending on if your provided callback threw an exception.

Heartbeat monitoring notifies Sentry of a job's status through one check-in. This setup will only notify you if your job didn't start when expected (missed). If you need to track a job to see if it exceeded its maximum runtime (failed), use check-ins instead.

Copied
// Execute your scheduled task...

// 🟢 Notify Sentry your job completed successfully:
\Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::ok(),
    duration: 10, // Optional duration in seconds
);

If your job execution fails, you can:

Copied
// 🔴 Notify Sentry your job has failed:
\Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::error(),
    duration: 10, // Optional duration in seconds
);

You can create and update your Monitors programmatically with code rather than creating and configuring them in Sentry.io.

Copied
// Create a crontab schedule object (every 10 minutes)
$monitorSchedule = \Sentry\MonitorSchedule::crontab('*/10 * * * *');

// Or create an interval schedule object (every 10 minutes)
$monitorSchedule = \Sentry\MonitorSchedule::interval(10, MonitorScheduleUnit::minute());

Supported units are:

  • MonitorScheduleUnit::minute()
  • MonitorScheduleUnit::hour()
  • MonitorScheduleUnit::day()
  • MonitorScheduleUnit::week()
  • MonitorScheduleUnit::month()
  • MonitorScheduleUnit::year()
Copied
// Create a config object
$monitorConfig = new \Sentry\MonitorConfig(
    $monitorSchedule,
    checkinMargin: 5, // Optional check-in margin in minutes
    maxRuntime: 15, // Optional max runtime in minutes
    timezone: 'Europe/Vienna', // Optional timezone
    failureIssueThreshold: 2 //Optional failure issue threshold
    recoveryThreshold: 5 // Optional recovery threshold
);

// 🟡 Notify Sentry your job is running:
$checkInId = \Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::inProgress(),
    monitorConfig: $monitorConfig,
);

// Execute your scheduled task here...

// 🟢 Notify Sentry your job has completed successfully:
\Sentry\captureCheckIn(
    slug: '<monitor-slug>',
    status: CheckInStatus::ok(),
    checkInId: $checkInId,
);

When your recurring job fails to check in (missed), runs beyond its configured maximum runtime (failed), or manually reports a failure, Sentry will create an error event with a tag to your monitor.

To receive alerts about these events:

  1. Navigate to Alerts in the sidebar.
  2. Create a new alert and select "Issues" under "Errors" as the alert type.
  3. Configure your alert and define a filter match to use: The event's tags match {key} {match} {value}.

Example: The event's tags match monitor.slug equals my-monitor-slug-here
