Windows Cluster Monitoring


Follow the steps given below to create a new Windows Cluster monitor in Applications Manager:

  1. Click on New Monitor link.

  2. Select Windows Cluster under the Servers category.

  3. Specify the Display Name of the Windows Cluster.
  4. Enter the Cluster Name or the IP Address of the cluster

  5. Select the Version of the Windows Server from the drop-down menu.
  6. You can either use your Cluster Domain Administrator username and password, or select credentials from the Credential Manager drop-down menu. To use your Cluster Domain Administrator credentials, make sure the user account has permission to excute WMI queries on 'root\mscluster' namespace in cluster server nodes.

  7. Select the Node Discovery option. The available options are Do not Discover Nodes and Discover and Monitor Nodes

    Do not Discover Nodes - Selecting this option will not discover the cluster server nodes as a Windows Server. If the node already added as windows server, it will be associated internally for collecting the event logs specific to cluster.

    Discover and Monitor Nodes - Selecting this option will discover the cluster server nodes as a Windows Server and monitor availability and performance. If the node already added as windows server , it will not be discovered again and the existing server will be associated internally for collecting the event logs specific to cluster.

  8. Select the Enable Event Log Monitoring option:

    • Checked - This will enable the eventlog monitoring in all the cluster server nodes. The events generated from the configured eventlog rules will be propagated to cluster. During the eventlog collection of servers, it will collect the events for cluster as well and add them to database without generating the alert. Then, during the data collection of cluster, it will take the cluster events from database from all the nodes and then generate the alert for the configured Eventlog rule.
    • Unchecked - This will disable the eventlog monitoring in the Cluster.
      • Cluster Add : While adding the cluster, selecting this option will not enable eventlog monitoring in the nodes discovered. If a node already exists, this option will leave the current event log status in the server as it is.
      • Cluster Update : If this option is selected while updating the cluster, it will disable event log monitoring in the all the servers & cluster. Also it will clear the eventlog related Alarms and Events from database for all the servers & cluster. Hence use this option only when it is necessary.
  9. Enter the polling interval time in minutes.

  10. Choose the Monitor Group from the combo box to which you want to associate the Monitor (optional).

  11. Click Add Monitor(s).

Monitored Parameters

Applications Manager's Windows Cluster monitoring capability includes monitoring of the cluster details, the cluster nodes, resource groups, cluster performance, networks, disk utilization and storage stats. You can also monitor the cluster events by configuring the Event log Rules.

 

The monitoring details of Windows Cluster are represented graphically that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored and in case of threshold violation you can get notified on this by associating Actions. This will also help, to get notified on the failover happened in the Cluster.

 

Availability tab, gives the Availability history for the past 24 hours or 30 days. Performance tab gives the Health Status and events for the past 24 hours or 30 days. List view enables you to perform bulk admin configurations. Click on the individual monitors listed, to view the following information.

 

The Windows Cluster attributes monitored are classified under the following tabs in Applications Manager:
