Measures reported by CouchDBDsnDcChTest

CouchDB supports special documents within databases known as “design documents”. These documents are mostly driven by JavaScript, used to build indexes, validate document updates, format query results and filter replications.

This test reveals whether/not the cache for the Design Document has been effectively utilized and helps assess the impact of this cache usage on the target server. From the metrics reported by this test, administrators can also figure out if the document cache needs any further fine-tuning.

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

The measures made by this test are as follows:
