StorePercentUsage not reported when running Broker embedded
Hi All,
I'm pretty new to ActiveMQ. I'm trying to make a demo with resource usage
notifications, and therefore was looking into stats one can read from JMX
MBeans. In my demo I'm creating a simple fast producer to write to queue and
leave it running without consumers (memory and store limits are set to
really low value ~ 5 and 10 Mb).
When starting ActiveMQ standalone app, everything works as expected:
MemoryPercentUsage grows until hits some number (69%) and stops, then
StorePercentUsage keeps growing until 100%, and then producer is blocked.
However, when starting broker embedded in my code, I can only observe
MemoryPercentUsage growing up to 69% while StorePercentUsage remains 0 all
the time. Broker just keeps storing undelivered messages as the KahaDB store
keeps growing (TotalEnqueueCount grows and I can observe how KahaDB files
are growing on a filesystem).
I have a feeling that some more settings should be provided through API.
Anyone can explain what exactly I'm doing wrong with embedded broker? For
clarity, attaching my broker code.
Thanks,
Art

Yes, that was my mistake -- now it works. Thank you!

there are some smarts in xbean that set the persistence adapter reference
for the storeUsage. I think in your case that link is lost.
Start with:
SystemUsage usage = org.apache.activemq.broker.BrokerService#getSystemUsage
then make your mods to the members in that and there necessary associations
will be in place.
