This test continuously monitors the query load on the each of the query dispatchers configured on the query matching servers, observes variations in the length of the query queues, and proactively isolates the following:

• a probable overload condition; you can even accurately identify which query dispatcher is handling the maximum load
• a potential handle leak and the query dispatcher responsible for the same;
• latencies in query processing

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 host for which the test is to be configured in the HOST text box.

• Specify the port on which the specified host listens in the PORT text box. By default, the port number is 54321.

• 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.
