Appendix: Alarm Messages Appendix: Metrics

VMW Resource Pool Percent Ready

Purpose

This rule fires an alarm to report that when a virtual machine within the resource pool is requesting CPU cycles from the ESX Server on which it is running, it is not receiving them some percentage of the time. This will impact performance on the virtual machine.

Scope

VMWResourcePool

 
Table 214. Rule Definition
Conditions
State
Action

When the virtual machine requests CPU cycles, it is only not receiving them 2 percent or less of the time.

Normal

None

When the virtual machine requests CPU cycles, it is not receiving them greater than 2 percent but no greater than 8 percent of the time.

Warning

None

When the virtual machine requests CPU cycles, it is not receiving them greater than 8 percent but no greater than 12 percent of the time.

Critical

VMW ESX Host Connected - No metrics rule

Purpose

This rule monitors ESX hosts that are powered on, connected, not in maintenance mode, yet do not return performance metrics.

Scope

VMWESXServerMemory

 
Table 215. Rule Definition
Conditions
State
Action

ESX hosts are connected and returning performance metrics.

Normal

None

An ESX host is in an unknown state. It is powered on and connected, but it is not returning any response from requests for performance metrics.

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.

Critical
