Failover Cluster Status Test
Whenever a user complains of the inaccessibility of a resource (i.e., a server/service/application), the administrator should first check whether that resource is part of a cluster, and if so, check whether the Windows cluster service has been enabled and is running on each node of the cluster. This is where the Failover Cluster Status test helps. This test reports whether a monitored node is part of a cluster or not and if so, indicates whether/not the cluster service is enabled and running on that node. This way, administrators can be promptly alerted to the sudden termination or the absence of the cluster service on a cluster node. In addition, the test also reports the composition of the cluster – i.e., the number of nodes and services/applications that have been clustered as part of the monitored cluster setup.
Target of the test : A node in a Windows cluster
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every cluster being monitored
Parameter | Description |
---|---|
Test Period |
How often should the test be executed |
Host |
The host for which the test is to be configured. |
Port |
The port at which the specified HOST listens. By default, this is Null. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

Measurement | Description | Measurement Unit | Interpretation | ||||||
---|---|---|---|---|---|---|---|---|---|
Is failover clutser installed? |
Indicates whether/not the cluster service is installed on the monitored node. |
|
The values that this measure can report and their corresponding numeric values have been listed in the table below:
Note: By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however will indicate whether/not the monitored server is cluster-enabled or not. |
||||||
Cluster status |
Indicates the current status of the cluster service on the target node. |
|
The values that this measure can report and their corresponding numeric values have been listed in the table below:
Note: By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however will indicate whether/not the cluster service is running using the numeric equivalents only. |
||||||
Is the cluster active? |
Indicates whether/not the cluster is currently active. |
|
The values that this measure can report and their corresponding numeric values have been listed in the table below:
Note: By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however will report the status of the cluster service using the numeric equivalents only. |
||||||
Number of services/applications |
Indicates the number of services/applications that are currently clustered under this cluster. |
Number |
To know which services/applications are currently clustered, use the detailed diagnosis of this measure. |
||||||
Number of nodes |
Indicates the number of nodes in this cluster. |
Number |
To know which nodes are the members of the cluster, use the detailed diagnosis of this measure. |
Use the detailed diagnosis of the Number of services/applications measure to know which services/applications have been configured for high availability under a cluster, and which cluster node owns each service/application.
