VMW ESX Server Queue Latency Deviation

Purpose

This rule fires when the Queue Command Latency for a physical disk in a VMware ESX Server exceeds the normal operating range, using the standard deviation. The Queue Command Latency for a collection interval is the time spent, per SCSI command, in the VM kernel queue.

Scope

VMWESXServerPhysicalDisk

 
Table 229. Rule Definition
Conditions
State
Action

The Queue Command Latency for a physical disk on all monitored ESX is within the normal operating range.

Normal

None

The Queue Command Latency for a physical disk on a monitored ESX host has entered the Warning state, when calculated using the standard deviation.

Warning

None

The Queue Command Latency for a physical disk on a monitored ESX host has entered the Critical state, when calculated using the standard deviation.

Critical

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 230. 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 231. 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
