VMW ESX Server Balloon Memory Deflation

Purpose

This rule monitors for servers working excessively to reclaim memory. To better balance memory utilization across servers within a cluster, you can add more physical resources to a server or you can use VMotion to move a virtual machine from one server to another.

Scope

VMWESXServerMemory

 
Table 216. Rule Definition
Conditions
State
Action

The balloon has not been growing excessively and is deflating normally.

Normal

None

The balloon has reached 20 percent of the server's memory over the course of the last 90 minutes and has failed to deflate to less than 5 percent over the last 15 minutes.

Warning

None

The balloon has reached 20 percent of the server's memory over the course of the last 90 minutes and has failed to deflate to less than 12 percent over the last 15 minutes.

VMW ESX Server Consumed Vs. Granted Memory

Purpose

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.

Scope

VMWESXServerMemory

 
Table 217. Rule Definition
Conditions
State
Action

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

Purpose

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.

Scope

VMWESXServerProcessor

 
Table 218. Rule Definition
Conditions
State
Action

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

Purpose

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

Scope

VMWESX Server

 
Table 219. Rule Definition
Conditions
State
Action

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
