Java Agent -100% CPU

[gruselglatz]

Hey,

We use the APM Java Agent 1.20.0 on Java 1.8.0_162 with apm-server 7.10.1 and strangely on two of our Hosts we get

system.process.cpu.total.norm.pct: -100%
system.cpu.total.norm.pct: -100%

On identical Hosts we get normal CPU Values.

The User which rans the Windows Service is also in the Performance Log Users and the Performance Monitor Users group.

I don't know what i should look for other then identical config, identical jvm identical Agent...

Thanks

Hi @gruselglatz,

In this case you need to take a thread dump for investigation, that will provide a snapshot on the current CPU activity when it's at 100%.

You should be able to get this with JConsole or VisualVM tools.

Hi @Sylvain_Juge,

We don't have a Problem with CPU Spikes, the APM-Agent reports -100% CPU (minus 100%). And I don't know why.
