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:

2G 190.2M of 2G

#3 running 2016-06-22 02:56:51 AM *2240.2% * 1.6G of
2G 190.2M of 2G

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:
