VMW ESX Server Consumed Vs. Granted Memory

This rule compares the amount of memory that is being requested by the virtual machines on an ESX Server to the amount of memory available on the ESX Server.

If the application workload of the ESX Server is requesting an excessive amount of the available memory resources, you must either add memory to the ESX Server or use VMotion to better balance the virtual machines across the servers within the cluster.

VMWESXServerMemory

Table 217. Rule Definition

The virtual machines on the server are requesting just 75 percent or less of the memory the server has available.

Normal

None

The virtual machines on the server are requesting more than 75 percent but no more than 83 percent of the memory the server has available.

Warning

None

The virtual machines on the server are requesting more than 83 percent but no more than 90 percent of the memory the server has available.

Critical

Send email to VMware administrator

The virtual machines on the server are requesting more than 90 percent of the memory the server has available.

VMW ESX Server CPU 0 High Utilization

This rule monitors for situations in which an incomplete SOAP message sent to the Web services API results in a dramatic increase in CPU usage on CPU 0 within an ESX Server or VirtualCenter.

VMWESXServerProcessor

Table 218. Rule Definition

The CPU usage on CPU 0 is not greater than 95 percent.

Normal

None

The CPU usage on CPU 0 is greater than 95 percent.

Fatal

None

VMW ESX Server CPU Estimated Fill Time

This rule determines when the ESX Server CPU is likely to reach its capacity, based on its present growth rate.

VMWESX Server

Table 219. Rule Definition

At the present growth rate, the ESX Server CPU will not reach its capacity within 90 days.

Normal

None

At the present growth rate, the ESX Server CPU will reach its capacity in 90 days or less.

Warning

None

At the present growth rate, the ESX Server CPU will reach its capacity in 30 days or less.

Critical

Send email to VMware administrator

At the present growth rate, the ESX Server CPU will reach its capacity in 7 days or less.

Fatal

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.

Critical
