Measures reported by LCResourStatusTest

A cluster resource is a resource that is required to be highly available for the business. Cluster resources can be either moved or replicated to one or more nodes within a cluster. A resource group is a convenient way of keeping resources together and it consist of more than one resource. The resource groups need to be located together, start sequentially, and stop in the reverse order. These cluster resources makes the service highly-available throughout all the nodes in the cluster. A Linux cluster can maintain multiple resource groups. A resource can be migrated from one resource group to another but it cannot exist in more than one group at a time. Often, failure of a resource group leads to the inaccessibility of the resources in that group. Moreover, if a resource is inaccessible or is stopped, then, users accessing the resource may face unexpected delays. To avoid this, it is necessary to monitor the state of the resource groups round the clock! LCResourStatusTest helps in this regard!

This test auto-discovers the resources in the target cluster and for each resource, this test reports the current status. Using this test, the resources that have been stopped frequently can be identified. The detailed diagnosis of this test helps administrators to find resource group name, resource name, resource type and node name.

Outputs of the test : One set of results for the Linux cluster resources being monitored

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Resource_status Indicates the current status of this resource.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Started 100
Stopped 0


Note:

By default, this measure reports the above-mentioned Measure Values to indicate the current state of the resources. The graph of this measure however, is represented using the numeric equivalents only i.e., 0and 100. The detailed diagnosis of this measure gives the resource group name, resource name, resource class, provider, resource type, and node name.
