Generate a flame graph for a post request #13

Open hraynaud opened 9 years ago

Hi I was wondering if it was possible to generate the flamegraph on a post request?.

SamSaffron commented 9 years ago

we should add a way of triggering this in rack mini profiler its mainly a UI problem, you can do this manually by writing middleware that detects the request and then generates a graph to a file.

Hi Sam thanks for the quick response. If you think it's not a huge undertaking I'm happy to take a crack at it if you can point me in the right direction.

first step is a sample on how to do this in rack middleware that you can add to a samples dir in flamegraph, you familiar with writing and inserting rack middleware?
