Default Parameters for MongoRepStatusTest

Using this test, administrators can keep track of the status of each member node and be promptly alerted if that node stops running or switches to an abnormal state. Furthermore, the test keeps tabs on heartbeats received from each member node, pinpoints the member node from which heartbeats were not received for a long time, and thus proactively alerts administrators to the potential non-availability of a node. This way, administrators will be able to ensure that quorum is maintained in the replica set and the primary node is able to communicate with each member node in the replica set. The test also notifies administrators if the primary of the replica set has switched. Detailed diagnostics reveals when the switch occurred and what is the current primary.

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

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

• The test connects to a specific Mongo database to run API commands and pull metrics of interest. Specify the name of this database in the DATABASE NAME text box. The default value of this parameter is admin.

• 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.
