Broker-J statistics and CPU consumption
Hello,
We're using the Broker-J 7.1.3.
Looking at the statistics provided by /api/latest/broker/getStatistics, I don't see anything related to the CPU consumption.
Did I miss something or this information is not provided?
Thanks,
Olivier

Probably worth starting a separate thread on that topic, as it's likely
that the Dispatch developers will skip this thread due to its title :-)

Thanks Rob.
This will help us a lot in monitoring the brokers.
By the way, any chance we can get something similar on the dispatch-router side?

I've created the JIRA QPID-8376
<https://issues.apache.org/jira/browse/QPID-8376> and made a change there which adds two statistics - processCpuTime (which is the cumulative CPU time since the app started) and processCpuLoad (which is the current CPU load due to the process, rounded to 4 decimal places) which will be retrieved if the underlying Java platform supports them.
Hope this helps,
Rob

I'm not sure there is huge value in reporting on the SystemLoadAverage -
that is the total load on the system, rather than just the load the Broker
is generating I think. As such it seems weird to ask the Broker to report
on it. As per my (very slightly earlier than yours) mail - there does seem
to be a mechanism on at least some Sun/Oracle JVMs to get the Process CPU
time. Again I'm still somewhat dubious as to whether this should be gather
from the broker itself, or whether this is more properly reported using
some sort of external monitoring tool.

Hi Olivier,
CPU consumption statistic is not available.
Potentially, cpu average load from
java.lang.management.OperatingSystemMXBean#getSystemLoadAverage can be
returned as part of broker statistics.
If you need OperatingSystemMXBean#getSystemLoadAverage() being exposed as
broker statistic, please raise JIRA.
Kind Regards,
Alex

Re: Broker-J statistics and CPU consumption

Hi Olivier,
no - there is nothing on CPU consumption. I don't believe there is any
standard way to get the CPU consumption from a Java process.
The closest I can find is that if the platform implementation of
OperatingSystemMXBean implements com.sun.management.OperatingSystemMXBean
then it will provide a long getProcessCpuTime() method.
Theoretically that could be added to the BrokerAttributeInjector in the
Qpid Broker-J codebase (in the same style as the other statistics are added
in that class).
