[Netarchivesuite-users] JMS-Queues

[aponb at gmx.at]

Yes there is only one consumer on the COMMON_MONITOR queue and the load 
on this machine is normal.
I try to find the setting to configure how often an application can 
request to be monitored.
When listing all queues, I realized that the ANY_LOWPRIORITY_HACO queue 
is growing (currently around 180 messages) and there is no active 
consumer on it. All other queues have extactly one consumer. Is this normal?

> Does imqcmd command for listing numbers of messages, producers, consumers on each queue tell you that there is one (and exactly one) consumer on the COMMON_MONITOR queue ? - the GUIApplication should take messages from that queue all the time meaning that number of messages should not grow. If GUIApplication stopped listening on that queue number of messages will off cause grow.

> That specific queue is used by all other applications to tell the monitoring system: "I want to be monitored" - you can configure how often each application should send this message - and maybe you could try to raise the setting (I recall it's set as Number Of Seconds between each message about "I want monitoring").
