VMW ESX Server CPU Utilization

This rule monitors for spikes, dramatic drops, and sustained high levels in CPU utilization for an ESX Server.

VMWESXServerCPUs

Table 220. Rule Definition

The CPU utilization is no more than 2.2 standard deviations from the mean CPU utilization and the CPU utilization is at 90 percent or less.

Normal

None

The CPU utilization is more than 2.2 but no more than 2.8 standard deviations from the mean CPU utilization, or the CPU utilization is greater than 90 percent but not greater than 93 percent.

Warning

None

The CPU utilization is more than 2.8 standard deviations from the mean CPU utilization, or the CPU utilization is greater than 93 percent.

VMW ESX Server Disconnected

This rule checks for a loss of connectivity between the VirtualCenter and an ESX Server that had virtual machines running on it.

VMWESXServer

Table 221. Rule Definition

The ESX Server, which has virtual machines running on it, is currently connected to the VirtualCenter.

Normal

None

The ESX Server, which had virtual machines running on it, is no longer connected to the VirtualCenter.

VMW ESX Server Disk IO

This rule monitors for spikes and drops in disk IO for an ESX Server.

VMWESXServerStorage

Table 222. Rule Definition

The disk usage is no more than 2.2 standard deviations (NumSTDevs) from the mean disk usage.

Normal

None

The disk usage is more than 2.2 but no more than 2.8 standard deviations from the mean disk usage.

Warning

None

The disk usage is more than 2.8 standard deviations from the mean disk usage.

Critical

None

VMW ESX Server Heap Free Memory

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.

VMWESXServerMemory

Table 223. Rule Definition

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.
