Default Parameters for 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.

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

• 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.

• 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.

• 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.
