ESX Server Rules
VMW ESX Server Heap Free Memory
Purpose
This rule monitors heap memory in the vmkernal and fires an alarm when the heap
memory for a particular ESX Server drops below a predefined amount.
If the amount of heap memory in the vmkernal for a particular ESX Server drops to the
critical level, you may want to add more physical memory to the server or use VMotion
to better balance memory utilization across servers within the cluster.
