 | | Introduction |
Cluster resources are used to monitor specific cluster attributes.
There are two classes of resources:
Cluster-level resource. These resources monitor attributes on a cluster-wide basis. For example, the MSCS resource monitors cluster-wide conditions such as the network.
Node-level resource. These resources monitor attributes of individual nodes. For example, the Disk resource monitors Disk capacity on each node in a cluster.
The majority of resources run on the central management server (CMS), and they use the SNMP protocol to poll the cluster nodes.
| | Which cluster resources are supported by HP Systems Insight Manager? |
HP Systems Insight Manager supports several standard resources : Disk CPU System (formerly ENV)
Disk and CPU resources monitor the Disk capacity and CPU utilization respectively. You can set minor and major thresholds for individual nodes in a cluster. When those thresholds are reached, Cluster Monitor creates an HP Systems Insight Manager event and a Cluster Monitor status message. The event triggers associated e-mail and paging notification as configured in the HP Systems Insight Manager options. The System resource provides a link to the cluster node home page. This resource was formerly called the ENV CMX which provided environment variables on the node home page. In addition, HP Systems Insight Manager supports the Microsoft Cluster Service (MSCS) resource. This resource monitors the status of the MSCS at a cluster level. The MSCS cluster condition reflects the most critical condition in Node, Network, and Resources lists. The following table explains the condition categories for each list.
