Appendix: Alarm Messages

VMW Cluster Percent Ready

Purpose
This rule fires an alarm to report that when a virtual machine within the cluster is requesting CPU cycles from the ESX Server on which it is running, it is not receiving them some percentage of the time. This impacts the performance on the virtual machine.
This rule is disabled by default, and can be enabled, as required.
Scope
VMWCluster
 
Table 190. 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 Cluster Redundancy Verification

Purpose
This rule fires an alarm to report that if an ESX Server within the cluster fails, the remaining servers in the cluster may not or do not have enough available CPU and/or memory to handle the increased workload.
Scope
VMWCluster
 
Table 191. Rule Definition
Conditions
State
Action
The cluster has sufficient redundant CPU and memory capacity to handle the failure of a single ESX Server.
Normal
None
Although the cluster can handle the failure of a single ESX Server, either the resulting combined CPU utilization or the resulting combined memory utilization on the remaining servers, or both, would be beyond the warning threshold. The resulting alarm message will indicate the values of both of the new combined utilizations.
Warning
None
If an ESX Server within the cluster fails, the remaining servers do not have the capacity to handle the increased workload. The resulting alarm message will indicate the values of both of the new combined utilizations.
Critical
None

Datacenter Rules

This section lists and describes the datacenter rules. These rules are disabled by default, and can be enabled as required.
Rule in this section:
•
VMW Datacenter CPU Utilization
•
VMW Datacenter Disk IO
•
VMW Datacenter Memory Utilization
•
VMW Datacenter Network IO
•
VMW Datacenter Percent Ready

VMW Datacenter CPU Utilization

Purpose
This rule monitors for spikes, dramatic drops, and sustained high levels in CPU utilization for a datacenter.
Scope
VMWDatacenter
 
Table 192. Rule Definition
Conditions
State
Action
The CPU utilization is no more than 2.2 standard deviations (NumSTDevs) 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
