Method and system for tracing end-to-end transaction, including browser side processing and end user performance experience

A performance management system that measures end user performance in a distributed computing environment, comprising:

• a client computing device;
• a monitoring computing device;
• a browser agent instrumented into content rendered by a web browser executing on the client computing device, the browser agent being configured to detect a content request sent by the web browser and send browser side monitoring data over a data network to the monitoring computing device located remotely from the client computing device, wherein the browser side monitoring data describes the content request and includes a session identifier that identifies an instance of the web browser;
• an event correlator executing on the monitoring computing device and configured to receive the browser side monitoring data from the browser agent;
• and
• a visit manager executing on the monitoring computing device and configured to determine duration between consecutive content requests received from the web browser and group the consecutive content requests from the web browser together to form a visit in response to the duration between the consecutive content requests being less than a visit threshold and generate a visit record for each visit of a plurality of visits to a monitored application, where the visit record is stored in a computer memory of the monitoring computing device;
• wherein the event correlator receives server side monitoring data and combines the server side monitoring data with the browser side monitoring data to form transactions between the monitored application and a particular web browser, where the server side monitoring data is caused by creation of the content that is requested by the content request embodied in the browser side monitoring data and the server side monitoring data is sent by server agents instrumented into methods executed by one or more application servers, and where the browser side monitoring data identifies the particular web browser and the monitored application is comprised of the methods executed by the one or more application servers.
