Client Side Performance Metrics

Hello,

 

 

I am working on a project to introduce client side performance monitoring into our hosted application for SLA measurement among other things. I the information below on a demo site for a ticketing system we use and thought there might be a way to inject something into the requests as they go out rather than deal with costly application changes. The information below is displayed on each page. Does anyone have any code that creates something like this? Mainly I'm looking for the server that serviced the request and the response time measured from the client side.

 

 

Response time(ms): 1813 server: 004 render: 172 parse: 125 network: 269
