Celery Monitoring Problems

Periodic tasks fail without alerts. Issues go undetected for days.

Silent Task Failures

Celery tasks fail without alerts. Exceptions get logged but not monitored. Critical periodic tasks stop running.

Schedule Drift

Beat schedules change but monitoring doesn't update. Manual sync required between code and monitoring config.

No Beat Visibility

Hard to know which tasks are scheduled and when. Beat schedule buried in config files and database.

Celery Monitoring Modes

Selective mode monitors marked tasks. MonitorAll monitors everything.

Celery Monitoring Features

Auto-discovery without configuration. No code changes in your tasks.

Never Breaks Tasks

All errors swallowed. Monitoring failures never crash tasks.

No Task Changes

Existing task code unchanged. Works with current implementation.

Signal-Based Pattern

Uses Celery signals. Monitors execution automatically.

Email notifications when tasks miss schedule or fail.

How It Works

Define Beat Schedule

Configure periodic tasks in your Celery Beat schedule. No code changes needed.

from celery.schedules import crontab

app.conf.beat_schedule = {
    'send-daily-report': {
        'task': 'tasks.send_report',
        'schedule': crontab(hour=9, minute=0),
    },
}

Auto-Discovery

Setup intercepts Beat schedule and creates monitors with same schedule.

✓ Monitor Created: "send-daily-report" - Daily at 9 AM

Automatic Alerts

Task execution pings CronRadar automatically. Failed or missed tasks trigger instant alerts.

Job Success

Automatic ping sent

Instant Alert

You're notified immediately
