[rabbitmq-discuss] Document HTTP API responses?

Fri Jun 3 00:30:22 BST 2011

Here's a quick peek at two responses to the /api/overview call. Same server software version.

{
"management_version":"2.4.1",
"statistics_level":"fine",

"message_stats":{"publish":2445210,"publish_details":{"rate":4.593489204928332,"last_event":1307046917111},"ack":31,"ack_details":{"rate":0,"last_event":1306966493190},"deliver":57,"deliver_details":{"rate":0,"last_event":1306966493190},"deliver_get":6228204,"deliver_get_details":{"rate":4.593484491297741,"last_event":1307046917111},"deliver_no_ack":6228147,"deliver_no_ack_details":{"rate":4.593484491297741,"last_event":1307046917111}},

"queue_totals":{"messages":44,"messages_ready":18,"messages_unacknowledged":26}

"statistics_level":"fine",

"message_stats":{"publish":11340,"publish_details":{"rate":0,"last_event":1307041432286},"ack":401,"ack_details":{"rate":0,"last_event":1307039730923},"deliver":401,"deliver_details":{"rate":0,"last_event":1307039730923},"deliver_get":215791,"deliver_get_details":{"rate":0,"last_event":1307041433196},"deliver_no_ack":215390,"deliver_no_ack_details":{"rate":0,"last_event":1307041433196}},

"queue_totals":{"messages":0,"messages_ready":0,"messages_unacknowledged":0},
"node":"rabbit at mybox",
"statistics_db_node":"rabbit at mybox",
"listeners":[{"node":"rabbit at mybox","protocol":"amqp","host":"mybox.example.com","ip_address":"::","port":5672},{"node":"rabbit at mybox","protocol":"stomp","host":"mybox.example.com","ip_address":"::","port":61613}]
}

#################################

As you can see, the second broker has 'node', 'statistics_db_node', and 'listeners', whereas the first broker does not. Just now I noticed we're supporting STOMP on one of the servers, but does that account for all of the differences above? What other JSON responses will be different because of this, and how? What other configuration options affect the JSON responses? How are they affected?

I'm testing against various different broker instances, and I'm finding that, although they're the same version, there are apparently circumstances that exist which make the same call return different collections of attributes across different servers. For example, some hosts' 'overview' have a 'listeners' attribute while others don't. For queues, some have a 'node' attribute (iirc), and others don't. I imagine there are more of these situations, and I'm wondering if these conditions are documented anywhere? This would obviously be useful to those writing any code against the API as well, not just module authors (think of the poor ops folks writing nagios checks!). :)
