A wealth of performance and debugging data can be found in your web server logs. Graphs and trend lines are far better tools than a terminal and the find utility for analyzing what's happening in your logs. In this talk, we'll demonstrate some simple workflows for converting what's in your logs into graphs.
Aaron Kulick (Xiphoid Industries), Cliff Crocker (Akamai)
We (Cliff Crocker & Aaron Kulick) will take the audience through a working session that will leave them with a functional Web Performance Dashboard that they can customize to their individual needs. We will cover some of the available open source projects and tools as well as discuss the importance of synthetic vs real user monitoring (R.U.M.) and how they can be combined in a single pane.
