Was this fixed in Cf-238? I cannot see a reference in the release notes. Is
there a pivotal tracker reference?

Thanks,
John

This is a known issue that is fixed which may come in the next release.
It is just off by 100.

Hi,

None of the CPU usage computations have changed in Diego recently. What
version of the CLI are you using? What does the CC stats endpoint,
accessible via `cf curl /v2/apps/$(cf app --guid APP_NAME)/stats`, report
for the CPU usage of the instances of this app?

Thanks,
Eric, CF Runtime Diego PM

Hi, there

After I upgrade cf deployment to cf 237 with diego 0.1472.0 recently,
cpu usage for apps became abnormal, it became extremely high (exceeds 100%
* cpu cores) as below:

The backend cell has 16 cores, not sure why the cpu usage execceeds
1600%. I checked the cpu usage from aws console, the cpu usage is about 2%.
Does cf 237 changed the cpu usage algorithm? I am wondering if the cli
displays Wrong cpu usage?

The app is running on diego and I am able to ssh it. "uptime" shows the
cpu load is not high:

vcap(a)mgg62798lgm:~$ uptime
06:15:09 up 20:30, 0 users, load average: 0.33, 0.25, 0.25


"iostat" shows:
