Re: Checking CPU and memory usage for an IOC

["Wang, Andrew via Tech-talk" <tech-talk@aps.anl.gov>]

All,

I was able to get iocStats working. However, there is a slight error in this document under the ao record section: https://www.slac.stanford.edu/grp/ssrl/spear/epics/site/devIocStats/README_devIocStats

Shouldn't cpuScanRate be cpu_scan_rate?

Thank you,

Andy

Hi Andy –

 

There is the iocStats module that might do what you are looking for: https://github.com/epics-modules/iocStats.

 

In particular, there is a record that specifically monitors CPU usage: https://github.com/epics-modules/iocStats/blob/master/iocAdmin/Db/ioc.template#L130 (as well as one for memory usage).

 

Cheers,

 

Simon

All,

 

This is a very general question, but I was curious if people here have been able to monitor CPU and memory usage of a particular IOC as it ran. If so, what was the approach you took to do so?

 

Thank you,

Andy
