Abstract: A system and method for monitoring network and application performance. In one embodiment the method comprises logging information on network interface card (NIC) events involving a web page transaction, logging information on web server events involving the web page transaction, logging information on client browser events involving the web page transaction, collecting the information on NIC events, the information on web server events, and the information on client browser events on a collector server, and correlating the information on NIC events, the information on web server events, and the information on client browser events. In a further embodiment, correlating the information may comprise correlating the information on NIC events with the information on web server events by grouping the events by a client address and by a server address and then matching pairs of NIC events and web server events by time and data transfer size.

Abstract: A method and system are provided for optimized instrumentation of web pages in a performance management system. A web server receives a request for a web page from a web client. A callout to a performance management agent is inserted into the requested web page. The web page, including the callout to the agent, is sent to the web client. The web client may use the callout to load the agent by sending a request for the agent to a collector server. The agent may collect performance metrics on the web client and send the performance metrics to the collector server for storage and/or analysis.
