Measures reported by RSAInstanceTest

A deployment of an RSA Authentication Manager appliance includes a primary instance, and one or more replica instances. The primary instance is the Authentication Manager appliance that you deployed initially. The replica instances are added to the deployment to provide deployment-level redundancy of the primary instance. This redundant deployment protects the appliance against unexpected failures and hardware disasters, facilitates scheduled maintenance, and ensures availability of all authentication services. In the deployment, the primary instance handles all administration and user authentication operations and replicates the operation log data on every replica instance. In such way, the replica instance is synchronized with the primary instance. Whenever the primary instance is under maintenance, is down or is failed, administrators may want the replica instance to take over quickly from the primary instance. If the replica instance is unresponsive or unable to take over the primary instance quickly, then, there may be too much of non-sync between the primary instance and the replica instance. This in turn will cause delay in authentication operations and result in data loss and performance lag. To avoid such eventualities, administrators should monitor replication health of the replica instance periodically. The RSAInstanceTest test aids administrators in this exercise!

This test auto-discovers the replica instances in the deployment, and accurately reveals the replication status of each replica instance.

The measures made by this test are as follows:

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

State Numeric value
Healthy 100
Out of sync 99

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current replication status of this instance. The graph of this measure however, represents the replication status of the instance using the numeric equivalents only - 100 and 99.
