VMW ESX Server Memory Utilization Upward Trend

Purpose
This rule monitors for upward trends in memory utilization for an ESX Server.
Scope
VMWESXServerMemory
 
Table 214. Rule Definition
Conditions
State
Action
Over the last ten minutes the mean memory has not increased (relative to the historical mean memory) by any more than 1 percent.
Normal
None
Over the last ten minutes the mean memory has increased (relative to the historical mean memory) by more than 1 percent but not by more than 2 percent.
Warning
None
Over the last ten minutes the mean memory has increased (relative to the historical mean memory) by more than 2 percent but not by more than 3 percent.
Critical
None
Over the last ten minutes the mean memory has increased (relative to the historical mean memory) by more than 3 percent.
Fatal
None

VMW ESX Server Network IO

Purpose
This rule monitors for spikes and dramatic drops in network IO for an ESX Server.
Scope
VMWESXServerNetwork
 
Table 215. Rule Definition
Conditions
State
Action
The network usage is no more than 2.2 standard deviations (NumSTDevs) from the mean network usage.
Normal
None
The network usage is more than 2.2 but no more than 2.8 standard deviations from the mean network usage.
Warning
None
The network usage is more than 2.8 standard deviations from the mean network usage.
Critical
None

VMW ESX Server Queue Latency

Purpose
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.
Scope
VMWESXServerPhysicalDisk
 
Table 216. 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

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 217. 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
