Improving XHProf Trace Analysis
With several waves of beta testers using the Tideways, we already recieved a fair share of feedback, both positive and negative. One point of criticism was centered around the user interface, particularly unexpected page reloads and weird back-button behavior.
In addition we have improved the summary of a trace to highlight the most relevant information for you.
New Graphical Tools
We have also added more graphical analysis tools. For XHProf traces two different sets of graphs are useful given exlusive and inclusive wall times of function calls:
For exclusive wall-times, that means the real performance impact of a function without all calls to child functions, we have introduced a treemap. The bigger the box of a function the more exclusive wall time it is using during the request.
By clicking on a box you can directly open the call details page.
For inclusive wall-times, own and child wall time, we added a so-called sunburst chart, starting in the middle with a circle for the
mainmethod of the analysed trace and adding layers of circles around it always proportionally to their share of the response time.
Both graphs should be considered experimental and we already have a list of improvements, however even in this early state they are invaluable for spotting performance problems.
Searching for Traces
In the performance section of your application, searching for a particular XHProf trace was not easy. To allow you find traces we have added a new feature: Search. You can filter by transaction names, HTTP method, urls, servers and many other criterias to find traces you are interested in.
Search will be improved in the next weeks to allow even more filtering and integrate more smoothly into the trace details view.
We are looking forward to your feedback on these new features.
