Failover cluster Nodes Test

The independent Windows systems that are grouped in a cluster and that work together as a unified computing resource are known as nodes. In a fail-over cluster typically, the cluster nodes are connected by physical cables and by software. If one of the nodes fails, another node begins to provide service through a process known as failover. As long as users have continuous access to the cluster resources, they will not care which cluster node is currently active and is serving their requests. Administrators on the other hand, may want to know which node in the cluster is active, and why certain nodes have gone down. To determine the same, administrators can run the Failover Cluster Nodes test. This test reports the current status of each node in every cluster that has been configured on the server, and thus points administrators to those cluster nodes that are currently down or whose operations have been paused.

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 each node in every cluster created

Configurable parameters for the test
  1. TEST PERIOD – How often should the test be executed
  2. Host - The host for which the test is to be configured.
  3. port – The port at which the specified HOST listens. By default, this is Null.
  4. DD frequency - Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against dd frequency.
  5. 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:

    • The eG manager license should allow the detailed diagnosis capability
    • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Cluster node status:

Indicates the current state of this node.


The values that this measure can report and the states they indicate have been listed in the table below:


Measure Value Numeric Value












By default, this measure can report the Measure Values mentioned above while indicating the current state of each cluster node. However, the graph of this measure is indicated using the numeric equivalents.

To know the network interface, network adapter, and other attributes a cluster node has been configured with, use the detailed diagnosis of this measure.
