VMW ESX Server Total Latency

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.

VMWESXServerPhysicalDisk

Table 60. 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	Send email to VMware administrator

VMW ESX Server Total Latency Deviation

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.

VMWESXServerPhysicalDisk

Table 61. 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	Send email to VMware administrator

VirtualCenter Rules

This section describes the VirtualCenter rule. This rule is disabled by default, and can be enabled as required:
