System health based on CPU iowait measurement

Synopsis

[OCF_RESKEY_state=string] [OCF_RESKEY_yellow_limit=integer] [OCF_RESKEY_red_limit=integer] [OCF_RESKEY_dampening=string]

HealthIOWait [start | stop | monitor | reload-agent | meta-data | validate-all]

Description

System health agent that measures the CPU iowait via top and updates the #health-iowait attribute.

Supported Parameters

OCF_RESKEY_state = string [/health-iowait-.state]

State file

Location to store the resource state in.

OCF_RESKEY_yellow_limit = integer [10]

Upper limit for yellow health attribute

Upper limit of iowait percentage to switch the health attribute to yellow. I.e. the #health-iowait will go yellow if the %iowait of the CPU gets higher than 10%.

OCF_RESKEY_red_limit = integer [15]

Upper limit for red health attribute

Upper limit of iowait percentage to switch the health attribute to red. I.e. the #health-iowait will go red if the %iowait of the CPU get higher than 15%.

OCF_RESKEY_dampening = string [5s]
