Appendix: Alarm Messages

VMW ESX Server Total Latency

Purpose
This rule fires when the total command latency (that is, the time taken during the collection interval to process a SCSI command issued by the guest OS to the virtual machine or the sum of kernelLatency and deviceLatency, based on data from the seven days prior to yesterday) of an ESX Server physical disk exceeds the normal operating range.
Scope
VMWESXServerPhysicalDisk
 
Table 218. Rule Definition
Conditions
State
Action
The total command latency is less than 25 milliseconds.
Normal
None
The total command latency is 25 milliseconds or greater, but no greater than 34 milliseconds.
Warning
None
The total command latency is 35 milliseconds or greater, but no greater than 39 milliseconds.
Critical
Send email to VMware administrator
The total command latency is 40 milliseconds or greater.
Fatal

VMW ESX Server Total Latency Deviation

Purpose
This rule fires when the total command latency (that is, the time taken during the collection interval to process a SCSI command issued by the guest OS to the virtual machine or the sum of kernelLatency and deviceLatency, based on data from the seven days prior to yesterday) of an ESX Server physical disk exceeds the normal operating range, using deviation.
Scope
VMWESXServerPhysicalDisk
 
Table 219. Rule Definition
Conditions
State
Action
The total command latency is no more than 2.2 standard deviations from the mean total command latency.
Normal
None
The total command latency is more than 2.2 but no more than 2.8 standard deviations from the mean total command latency.
Warning
None
The total command latency is more than 2.8 standard deviations from the mean total command latency.
Critical

Rules in this section:
•
VMW VirtualCenter CPU Utilization
•
VMW VirtualCenter Disk IO
•
VMW VirtualCenter Memory Utilization
•
VMW VirtualCenter Network IO
•
VMW VirtualCenter Percent Ready

VMW VirtualCenter CPU Utilization

Purpose
This rule monitors for spikes, dramatic drops, and sustained high levels in CPU utilization for a VirtualCenter.
Scope
VMWVirtualCenter
 
Table 220. 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
