Hello @Wai Keat C.
It is telling us that out of 100% available CPU, 97% used by the instrumented process(s). You can check the high CPU consuming process(s) and then can analyze why the process(s) are using more CPU.
Hello @Michael D.
Your point is valid. I would say this could be some type of misbehavior of the instrumented processes.
The following screenshot is an example where the process is showing more CPU then Host, but in your case process reached near about up to 100% intermittently.
