Symfony Messenger Monitoring

Ensure your Messenger workers process messages without interruption.

Symfony Messenger manages your async queues: emails, notifications, heavy processing. Your workers must run 24/7 to process these messages. But how do you know if a worker crashed at 4am?

MoniTao monitors your workers via heartbeat. Configure a periodic ping message, and get alerted as soon as a worker stops processing.

FAQ - Symfony Messenger

How do I monitor multiple parallel workers?

Each worker can have its own ping token. Or use a common message that all workers can process (the first one to receive it pings).

Can the ping message block the queue?

Not if you prioritize it correctly. Place it on a dedicated "heartbeat" transport with high priority so it's always processed quickly.

How do I detect a queue filling up without being processed?

Combine heartbeat (worker active) with queue size monitoring via your application dashboard. MoniTao confirms the worker is running.

Can I use Supervisor to restart workers?

Yes, and it's recommended. Supervisor + MoniTao = workers that auto-restart + you're alerted when it happens. Double security.
