@Edward,
You’ve configured the Xdebug profiler output filename in such a way that it overwrites the output file, each time, you run the process.
%u, %H, %R
– you mentioned in the output name are called format specifiers.
There are couple of ways to figure out which file you may want to analyze.
- Use
%t
(timestamp) format specifier in your output filename so you may know which file to analyze based on the timestamp value. - Instead of enabling the profiler throughout, you could trigger the profiler by passing a query arg as described here. This way you will only generate the Xdebug profiler output for the intended page. (Recommended)
