Configuration of CouchDBLogsTest

As messages keep getting logged in the log files, these log files grow large in size. If log file growth is left unchecked, it can consume all available space in the database. Administrators can effectively tracklog file growth and initiate measures to control it using the CouchDBLogsTest. The test reports the current size of the log files and their growth rate, and proactively alerts administrators if the rate of growth is abnormal.

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.

• Set ISUTF 16 flag to Yes, if the test needs to use the UTF-16 encoding format for reading the specified log files. By default, this flag is set to No.

• Specify the full path to the log file that is to be read by the test to pull out the metrics in the FILEPATH textbox.

• DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

• 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.
