Adding support in CPU monitoring
Adding two new collectors and a controller to enable
monitoring the CPU tuning parameters: vcpu_quota, vcpu_period.
This patch is part of the CPU SLA feature: http://www.ovirt.org/Features/CPU_SLA.
Changes in collectors:
Added a new utility method to Collector.py, "count_int",
count the number of matches in a string according to a regular expression.
Added HostCpu to expose the number of cpu on the host.
Added GuestCpuTune to expose the current tuning parameters and the latest user selection
Changes in controller:
Added CpuTune to apply changes to the vcpu tuning.
This patch is used in the cputune.policy, some code snip:
(defvar anchor 100000)
(def check_and_set_quota (guest)
{
(defvar calcQuota (/ (* anchor (/ guest.user_vcpu_limit 100))) guest.vcpu_count)
(if (!= guest.vcpu_quota calcQuota)
(guest.Control "vcpu_quota" calcQuota) 0)
})
