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] The time to wait (dampening) in seconds for further changes before writing The time to wait (dampening) in seconds for further changes before writing
