VMW Virtual Machine Logical Drive Utilization

This rule monitors disk utilization and fires when the disk utilization reaches 90 percent or greater.

VMWVirtualMachineLogicalDisk

Table 66. Rule Definition

The disk utilization is less than 90 percent.

Normal

None

The disk utilization is 90 percent or greater, but less than 95 percent.

This rule monitors for the swapping in and out of virtual machine memory.

VMWVirtualMachineMemory

Table 67. Rule Definition

The virtual machine has not moved any of its memory from its physical pages to the VMware swap file within the ESX Server.

Normal

None

The virtual machine has moved some of its memory from its physical pages to the VMware swap file within the ESX Server. This may adversely affect the virtual machine’s performance.

Virtual Switch Rules

This section lists and describes the virtual switch rules.

Rules in this section:

VMW Distributed Virtual Switch Available Ports

This rule checks for available ports on VMware distributed virtual switches.

VMWDistributedVirtualSwitch

Table 68. Rule Definition

The number of available ports on a distributed virtual switch is greater than the value set by the VMW:DistributedVirtualSwitchAvailablePorts.warning registry variable. The global default value of this variable is 20, meaning that in a default installation each of the monitored distributed virtual switches has more than 20 available ports.

Normal

None

The number of available ports on a distributed virtual switch reached the value set by the VMW:DistributedVirtualSwitchAvailablePorts.warning registry variable. The global default value of this variable is 20, meaning that in a default installation a Warning alarm is generated if a distributed virtual switch has 20 or fewer available ports.

Warning

None

The number of available ports on a distributed virtual switch reached the value set by the VMW:DistributedVirtualSwitchAvailablePorts.critical registry variable. The global default value of this variable is 10, meaning that in a default installation a Critical alarm is generated if a distributed virtual switch has 10 or fewer available ports.

Critical

None

The number of available ports on a distributed virtual switch reached the value set by the VMW:DistributedVirtualSwitchAvailablePorts.fatal registry variable. The global default value of this variable is 5, meaning that in a default installation a Fatal alarm is generated if a distributed virtual switch has 5 or fewer available ports.

Fatal

None
