Configuration of CouchDBShrCachtest

This test reports the rate of hits on the shared cache, the rate of shared cache that were missed and were totally evicted. By keeping an eye on these metrics over time, administrators can proactively detect a consistent drop in cache hits, investigate the reasons for the same, and promptly initiate measures to improve cache usage and safeguard the server performance.

The default parameters associated with this test are:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • Specify the IP address of the target server that is being monitored in the HOST text box.

  • Specify the port number through which the Couchdb server communicates in the PORT text box. The default port is 5984.

  • In order to monitor an Apache CouchDB server, a special database user account with Admin privilege has to be created in every Apache CouchDB server instance that requires monitoring. In the USERNAME text box, specify the Username for monitoring the target Apache CouchDB server instance.To create a new user, refer Creating a new user on Apache CouchDB topic.

  • Specify the password of the specified Username in the PASSWORD textbox.

  • Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD text box.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
