Measures reported by CouchDBRdRepTest

When data object replicas become inconsistent, read repair is a mechanism to make them consistent by overwriting the out-of-date replica with the latest value. This feature is typically found when peer replication is used and is not relevant in master-slave architectures. When data object replicas become inconsistent, read repair is a mechanism to make them consistent by overwriting the out-of-date replica with the latest value. This feature is typically found when peer replication is used.

Using this test, administrators can figure out the count of background read repairs. By analyzing the count of read repairs at regular intervals, administrators can figure out the erratic pattern of read repairs and figure out the exact cause of such erratic behavior.

Outputs of the test : One set of results for the target Apache CouchDB Server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
num_Of_Success_Reads Indicates the number of successful read repairs. Number A very high value is required for this measure.
num_Of_Failure_Reads Indicates the number of failure read repairs. Number Ideally, the value of this measure should be low.
total_Reads Indicates the total number of read repairs. Number
