Default Parameters for 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.

This page depicts the default parameters that need to be configured for the CouchDBShrCachtest.

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

• 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.

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

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
