Yesterday evening, we got a new Kafka lag. Detect if one of the sentry_post_process_forwarder_ container dies. If so, check log for message and if applicable, apply automatically procedure described in the NOG: https://agora.nasqueron.org/Operations_grimoire/Sentry#Kafka That would mean: # Notify the operation start # Stop both containers, as we can update offset as long as a client is connected to that consumer group # Reset Kafka offset # Start both containers # Notify the operation is done If it's another error, as we've a script on it, it would be nice if it creates a task on DevCentral with the log tail. Notification can be done with notification-push Docker Tide can be used to detect the need for healing
