A monitoring system allows users to monitor the performance of a web-based or other transactional server. The system includes an agent component ("agent") which simulates the actions of actual users of the transactional server while monitoring the server's performance. The agent may run on agent computers at a variety of locations. Using a controller component of the system, a user can preferably select a group of agent computers to include in a monitoring session, and assign transactions and execution schedules to such computers. Performance data collected from the agent computers is displayed by a web-based reports server that provides features for viewing the data as seen by agent computers having specific attributes or attribute sets. The system also includes features for capturing and displaying screens returned by the transactional server on failed transactions, and for measuring and reporting segment delays between an agent computer and the transactional server. |
