[rabbitmq-discuss] Monitoring Rabbit MQ deadletter queue and queue counts / rates

Thu Feb 13 15:17:49 GMT 2014

Thanks Michael,

Is there anything that describes the json that is returned for each api call.   For instance.  When I look at a specific queue 

http://machinename.domain.local:15672/api/queues/%2f/ohq.member.biometrics

 I get the following.   Im not sure how the json return is formatted.   

{"memory":14456,"message_stats":{"ack":8628,"ack_details":{"rate":0.0},"deliver":8628,"deliver_details":{"rate":0.2},"deliver_get":8628,"deliver_get_details":{"rate":0.2},"publish":8628,"publish_details":{"rate":0.0}},"messages":0,"messages_details":{"rate":0.2},"messages_ready":0,"messages_ready_details":{"rate":0.0},"messages_unacknowledged":0,"messages_unacknowledged_details":{"rate":0.2},"idle_since":"2014-02-13 9:08:36","policy":"","exclusive_consumer_tag":"","consumers":2,"backing_queue_status":{"q1":0,"q2":0,"delta":["delta",0,0,0],"q3":0,"q4":0,"len":0,"pending_acks":0,"target_ram_count":"infinity","ram_msg_count":0,"ram_ack_count":0,"next_seq_id":8628,"persistent_count":0,"avg_ingress_rate":0.040558057784930594,"avg_egress_rate":0.040558057784930594,"avg_ack_ingress_rate":0.040558057784930594,"avg_ack_egress_rate":0.0},"status":"running","incoming":[{"stats":{"publish":8628,"publish_details":{"rate":0.0}},"exchange":{"name":"ohx.notification","vhost":"/"}}],"deliveries":[{"stats":{"deliver_get":4342,"deliver_get_details":{"rate":0.0},"deliver":4342,"deliver_details":{"rate":0.0},"ack":4342,"ack_details":{"rate":0.0}},"channel_details":{"name":"11.1.4.69:60042 -> 11.1.4.64:5672 (2)","number":2,"connection_name":"11.1.4.69:60042 -> 11.1.4.64:5672","peer_port":60042,"peer_host":"11.1.4.69"}},{"stats":{"deliver_get":4286,"deliver_get_details":{"rate":0.2},"deliver":4286,"deliver_details":{"rate":0.2},"ack":4286,"ack_details":{"rate":0.0}},"channel_details":{"name":"11.1.4.68:57698 -> 11.1.4.64:5672 (2)","number":2,"connection_name":"11.1.4.68:57698 -> 11.1.4.64:5672","peer_port":57698,"peer_host":"11.1.4.68"}}],"consumer_details":[{"channel_details":{"name":"11.1.4.68:57698 -> 11.1.4.64:5672 (2)","number":2,"connection_name":"11.1.4.68:57698 -> 11.1.4.64:5672","peer_port":57698,"peer_host":"11.1.4.68"},"queue":{"name":"ohq.member.biometrics","vhost":"/"},"consumer_tag":"ohq.member.biometrics-1391823274000-472244183023","exclusive":false,"ack_required":true},{"channel_details":{"name":"11.1.4.69:60042 -> 11.1.4.64:5672 (2)","number":2,"connection_name":"11.1.4.69:60042 -> 11.1.4.64:5672","peer_port":60042,"peer_host":"11.1.4.69"},"queue":{"name":"ohq.member.biometrics","vhost":"/"},"consumer_tag":"ohq.member.biometrics-1391823324000-377170445325","exclusive":false,"ack_required":true}],"name":"ohq.member.biometrics","vhost":"/","durable":true,"auto_delete":false,"arguments":{"x-dead-letter-exchange":"ohx.deadletter","x-dead-letter-routing-key":"member.biometrics"},"node":"rabbit at Machine01"}

In RabbitMQ, deadlettered messages are published to a deadletter exchange:
http://www.rabbitmq.com/dlx.html

You can monitor ingress rate for an exchange:
> http://machinename.domain.local:15672/api/exchanges

or

> http://machinename.domain.local:15672/api/exchanges/[name]
