Failover Cluster Network Connections Test

A failover cluster requires network connectivity among nodes and between clients and nodes. Problems with a network adapter or Ethernet ports or other network device (either physical problems or configuration problems) can interfere with connectivity. Administrators should therefore check the connectivity status of the network adapters/devices/Ethernet ports round the clock to avoid failure of the failover cluster. The Failover Cluster Network Connections test helps administrators in this regard!

This test reports the current network connection state of each Ethernet port in the failover cluster. Using this test, administrators can proactively detect abnormalities in the failover cluster and maintain communication between the clients and nodes within the cluster.

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 Ethernet port in the failover cluster being monitored

Configurable parameters for the test

TEST PERIOD – How often should the test be executed Host - The IP address of the host for which the test is to be configured. 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
Network connection status:	Indicates the current network connection status of each Ethernet port in this cluster.		The values that this measure can report and the states they indicate have been listed in the table below: State Numeric value Up 100 Available 70 Failed 50 Unreachable 30 Unknown 10 Note: By default, this measure can report the State mentioned above while indicating the current network connection state of each Ethernet port. However, the graph of this measure is indicated using the numeric equivalents. The detailed diagnosis of this measure lists the name of the network, the name of the adapter, the ID of the network adapter and the IP address.
