Hi,
Looking for a queue or topic that had a large number of unconsumed messages
would probably be a good star
t.
If your
server
has the webconsole activated you can look at the queues and topics,
for example if your server had a webconsole on port 8161:
http://<server>:8161//admin/queues.jsp
http://<server>:8161//admin/topics.jsp
If your server has JMX enabled, you could connect to it with JConsole and
browse
t
he MBeans for the broker, looking at the MemoryPercentUsage attributes of
the
queues and topics.
Or, if the server has the jolokia JMX to HTTP bridge enabled, you can
access the MBeans via that:
$
curl -s -d
'{"type":"read","mbean":"org.apache.activemq:brokerName=amq-prod-1,destinationName=AL.FAILED,destinationType=Queue,type=Broker","attribute":"MemoryPercentUsage"}'
http://amq-prod-1
a
:8161/api/jolokia/ | jq .
{
"timestamp": 1460643204,
"status": 200,
"request": {
"mbean":
"org.apache.activemq:brokerName=amq-prod-1,destinationName=AL.FAILED,destinationType=Queue,type=Broker",
"attribute": "MemoryPercentUsage",
"type": "read"
},
"value": 0
}
That example shows me querying my server amq-prod-1a (broker name
amq-prod-1), and asking it to tell me the MemoryPercentUsage of the
AL.FAILED queue. The value happens to be zero in this case, so it's not
using any memory.
