Hi,
I confirm some metrics System|RQ will not be expected to report and this is known behavior, but for some metrics like "Volumes" etc, Can you please try below:
Switch from default javahardware monitor to hardware monitor by toggling <enabled> boolean flag from false to true and see how it goes:
disabled at /home/netstraw/machineagent/monitors/JavaHardwareMonitor/monitor.xml
enable at /home/netstraw/machineagent/monitors/HardwareMonitor/monitor.xml and restart jvm, we do not see any specific errors and also do not see any references to volumes related metric in logs
and given that OS is HP UX we need try with hardware script once OR this could be that the missing metrics are not being reported by java default h/w monitor itself
