Enabling Monitoring And Configuring The Monitor Script; Configuring Resource Monitoring - Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual

You also need to personalize the script by replacing variables with actual values for your
specific configuration, such as the mount point, IP address, container name, file system type,
and device.
6 Specify the Unload Script Timeout value, then click Apply to save the script or, if you are
creating a new cluster resource, click Next.
The timeout value determines how much time the script is given to complete. If the script does
not complete within the specified time, the resource becomes comatose when migrating to
another node. Cluster Services marks the process as failed right after the defined timeout
expires, but it must wait for the process to conclude before it can start other resource
operations.

Resource monitoring monitors the health of specified resources using scripts that you create or

9.6.1 Configuring Resource Monitoring

Although Novell Cluster Services can detect a node failure, it also has the ability to detect when an
individual resource on a node has failed. If you want Novell Cluster Services to check the health
status of a resource, you must enable and configure resource monitoring for that resource. Enabling
resource monitoring requires you to specify a polling interval, a failure rate, and a failure action.
If you are creating a new cluster resource, the Monitor Script page should already be displayed. You
can start with Step 5.
To configure resource monitoring:
1 In iManager, click Clusters, then click Cluster Options.
2 Browse to locate and select the Cluster object of the cluster you want to manage.
3 Select the check box next to the resource that you want to configure monitoring for, then click
the Details link.
4 Click the Monitoring tab.
5 Select the Enable Resource Monitoring check box to enable resource monitoring for the
selected resource.
Resource monitoring is disabled by default.
6 For the polling interval, specify how often you want the resource monitoring script for this
resource to run.
You can choose to specify the number in minutes or seconds.
