VMW ESX Server Queue Latency

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

VMWESXServerPhysicalDisk

Table 228. Rule Definition
Conditions	State	Action
The Queue Command Latency for a physical disk on all monitored ESX hosts does not exceed the number of milliseconds set by the VMW:diskQueueLatency.warning registry variable. The global default value of this variable is 25.	Normal	None
The Queue Command Latency for a physical disk on a monitored ESX host has exceeded the number of milliseconds set by the VMW:diskQueueLatency.warning registry variable. The global default value of this variable is 25.	Warning	None
The Queue Command Latency for a physical disk on a monitored ESX host has exceeded the number of milliseconds set by the VMW:diskQueueLatency.critical registry variable. The global default value of this variable is 35.	Critical	Send email to VMware administrator
The Queue Command Latency for a physical disk on a monitored ESX host has exceeded the number of milliseconds set by the VMW:diskQueueLatency.fatal registry variable. The global default value of this variable is 40.	Fatal	Send email to VMware administrator

VMW ESX Server Queue Latency Deviation

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.

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	Send email to VMware administrator

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 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	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 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	Send email to VMware administrator
