 Description   

Please implement %guest utilization.

Since Linux 2.6.24 cpu utilization contains also %guest utilization, which is the time spent running a virtual CPU for guest operating systems under the control of the Linux kernel.
Current Zabbix doesnt' support this utilization - tested 2.3.1 (revision 45994). Keep in mind that guest usage is not always available - it depends on kernel version.

Also, since Linux 2.6.33 cpu utilization contains %guest_nice.

(1) CPU collector does not parse the guest, guest_nice values from /proc/stat

(2) Documentation should be updated, at least in the following locations:

"What's new" for Zabbix 3.0 should probably be updated, too.

jurism Documented. RESOLVED.

wiper shouldn't 3.0 documentation be updated rather than 2.4 ?

jurism Entries moved to the correct documentation versions.
