Pega Platform™ captures information about the performance of request processing in your application and stores the information in PAL timers and PAL counters. You can view PAL statistics for each event. When the processing of a browser or service request causes delays, PDC analyzes PAL statistics from the relevant alerts and identifies possible sources of delays in request processing in your system.

The total request time is measured as the time required to process a request: from the time when a Pega Platform server receives the service request from an external system until Pega Platform sends the response to the external system or client. PAL statistics from the PEGA0001 and PEGA0011 alerts provide a reliable image of the performance of the entire request processing. These events can help you to identify the area of your system where you should start resolving the problem. For more information about interpreting PAL statistics, see Track system utilization for a requestor session with Performance Analyzer.
