Why is the JVM CPU usage exceeding 10,000?

[gqzis0726]

When we collected JVM information for container applications, we found that the CPU usage of a single JVM instance exceeded 100%, even reaching hundreds of thousands. Is this normal? Looking at the source code, it shouldn't exceed 100%.

I don't see this kind of issue here. Maybe your CPU spec is different? You could check the codes on your OS/CPU to verify.

Is it normal for the number to exceed 100?

[wu-sheng]

100 means 100% in that table. So it is common to be over 100. But your case is far more than that. I am not sure.

[gqzis0726]

Yes, all other pods are working normally; only a few pods are showing a CPU usage rate far exceeding 100% for data collection.
What methods can I use to pinpoint the cause?

I never saw this happen before in my experience. So, a little hard to tell.
