Configuration of CouchDBIndrTest

This test monitors the target CouchDB server and reports the number of indexers running on the server. In addition, this test also reveals the number of indexers running for a long time and also reports the running time of indexer greater than the configured running time. Using this test, administrators can be alerted to irregularities in indexing operations if any, and rectify them at a faster pace.

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.

• Specify the duration (in seconds) for which a indexing should have executed for it to be regarded as a long running indexers in the RUNNING DURATION SECONDS textbox. The default value is 10.

• To make diagnosis more efficient and accurate, eG embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test, by default, for a particular server, choose the On option against DETAILED DIAGNOSIS. To disable the capability, click on the Off option.

  The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability.

  • Both the bad and normal frequencies configured for the detailed diagnosis measures should not be 0.

• 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.
