> but accordin to the API doc of getSystemCpuLoad, it will return [0.0,1.0], how can it return Nan? Can you paste the API doc of getSystemCpuLoad, I do not find the description about [0.0,1.0] when I check the source code java doc. But it actually returns NaN in my laptop. So I think there are two things need to do. 1.Find why it returns NaN. And I found the issue https://github.com/naver/pinpoint/issues/914, and it use the same `OperatingSystemMXBean.getSystemCpuLoad()`, and also returns NaN. 2.I think whatever the reason is, it's better to add Double.isNaN check. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
