# ocf\_pacemaker\_HealthIOWait(7)

System health based on CPU iowait measurement

## NAME

ocf\_pacemaker\_HealthIOWait - 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 \[5s\]
