Testing dispatchers

To evaluate how IBM® Cognos® software is performing, you can test the status of dispatchers.

You can also ensure that the dispatchers are responding and view the uptime, which is the time in seconds during which the dispatchers are working without failure.

You can view the status of dispatchers and service and review log messages.

Before you begin

When you test a dispatcher, you also test the services that belong to that dispatcher.

You must have the required permissions to access IBM Cognos Administration Secured Functions and Features.

Procedure

In IBM Cognos Administration, on the Status tab, click System.

Determine the dispatchers that you want to test then follow the instructions in this table. In the Scorecard pane, from the change view menu of the current view, click the items you want to display.

Tip: The current view is one of All servers, All server groups, All dispatchers, or Services.

Table 1. Goals, views, and actions for testing dispatchers
