Measures reported by FCCluWmiStatusTest

WMI is Windows Management Instrumentation, which is an interface through which Windows components can provide information and notifications to each other, often between remote computers. Failover Clustering and System Center Virtual Machine Manager (SCVMM) often use WMI to communicate between cluster nodes, so if there is an issue contacting a cluster node, it is primarily essential to see if the WMI service is up and running. In some cases, the cluster nodes may not be able to communicate with each other even when the WMI service is up and running much to the agony of the administrators. To troubleshoot this communication failure, administrators should often verify if the namespace of the WMI service for the cluster is available to all the cluster nodes. The FCCluWmiStatusTest comes in handy to the administrators in this regard!

This test reports the current state of the WMI service and if the WMI service is running, this test will also report the connectivity status of the failover cluster WMI.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
State Indicates the current state of the WMI service.   The values that this measure can report and the states they indicate have been listed in the table below:

Measure Value Numeric Value
Running 100
Start Pending 90
Continue Pending 70
Pause Pending 60
Paused 50
Stop Pending 20
Stopped 10

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current state of the WMI. However, the graph of this measure is indicated using the numeric equivalents.
Wmi_connectivity Indicates the connectivity status of the failover clustering WMI.   The values that this measure can report and the states they indicate have been listed in the table below:

Measure Value Numeric Value
Connected 100
Not Connected 10
Not Installed 50

Note:

By default, this measure can report the Measure Values mentioned above while indicating the connectivity status of the failover clustering WMI. However, the graph of this measure is indicated using the numeric equivalents.
