Why Procstat cpu_iowait is always equal to zero :(

Tested on doens instances with different computations. It’s always equal to zero. But as I see with manual cheking real waiting time isn’t zero.

is the any way to fix this bug?

It is bug #2627, we need to remove some fields from this plugin since we don’t know the value on a per process basis. I believe you can get these values at a system level using the cpu input though. Sorry about the confusion.

ok, thx, Could you please help what plugin/field we can use for cpu_iowait for the total cpu?

This can be collected with the cpu input plugin.
