Configuration of MongoNetTest

This test periodically checks the whether/not the MongoDB server is up and running, verifies network connectivity to the server, and also measures the connection time. In addition, the test also emulates a MongoDB API call to a specified collection on the server for retrieving documents from it; in the process, the test reports collection availability and the time taken to read the documents. This way, the test alerts administrators to the non-availability and poor responsiveness of the server, and also points them to where exactly the bottleneck is.

The default parameters associated with this test are as follows:

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

• In the HOST text box, specify the IP address of the Mongo database server for which this test is to be configured.

• In the PORT text box, specify the port number through which the Mongo database server communicates. By default, this is 27107.

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

• A collection is the equivalent of an RDBMS table, which exists within a single database. A collection contains MongoDB documents. This test emulates a MongoDBI API call to a collection, and attempts to read the documents contained within. In the process, the test captures the collection availability and the time taken by the document read/retrieval operation. To enable this emulation, specify the name of the collection that you want the test to access, in the COLLECTION NAME text box. Your specification should be of the following format: <Namespace>.<collection name>. The default value of this parameter is system.indexes.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box 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.
