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.
Scope
VMWESXServerMemory
 
Table 211. Rule Definition
Conditions
State
Action
The amount of free memory in the vmkernal for the ESX Server is 7,680 KB or more.
Normal
None
The amount of free memory in the vmkernal for the ESX Server is less than 7,680 KB but not less than 3,584 KB.
Critical
Send email to VMware administrator
The amount of free memory in the vmkernal for the ESX Server is less than 3,584 KB.

Purpose
This rule determines when the ESX Server memory is likely to reach its capacity, based on its present growth rate.
Scope
VMWESX Server
 
Table 212. Rule Definition
Conditions
State
Action
At the present growth rate, the ESX Server memory will not reach its capacity within 90 days.
