When you launch a profiling session, a dialog appears by default, asking if you want to switch to the Apama Profiler perspective. You can change this behavior by selecting one of the following options buttons:

By default, the Apama profiler polls for data automatically (Automatic Refresh), using the refresh interval (in seconds) that is defined in the Refresh interval field and then updates the display in the Execution Statistics view. You can change the polling frequency by specifying the desired value in this field.

You can also change the way the profiler updates the data from a polling mode (Automatic Refresh) to an to an on-demand mode (Manual Refresh). The manual refresh is useful, for example, if you want to let your application run up to a certain point and then retrieve profile data, or if you want to inject a set of test events and then examine the profile deltas. To do the manual refresh, you click the corresponding button in the local toolbar of the Profiling Monitor view. See also Profiling Monitor view.
