Warning in OneAgent Log File: ruxitagent_host_xxxxx.log

Frequent Guest

Hi to All the DT Gurus,


One of our servers facing a strange OneAgent CPU Usage issue, it looks like the oneagentos.exe will have 100% CPU spikes every hour and last for a few minutes.


After I investigate the logs files, I came to this warning and I am not sure what does it means.


May I know anyone here who face the same issue before?


Thanks in advance.

Hi @siewsphone,


If you haven't already, I'd say the best course of action here would be to open a support ticket with Dynatrace.


@siewsphoneRe-install if that works it seems OA got corrupted some how.  if that doent work then you should go with support ticket which is suggested by Andre too.

Thanks all, currently working with Dynatrace support on this issue and they also have a problem identifying the root cause.

Did you setup any declarative process groups ? As i see "Regrouping processes due to declarative configuration changes" line in your log.
