I have been playing with the heap profiling graphs from ghc and find them quite useful and was wondering if there was a tool to display them in real-time? For interactive long-running applications written in haskell it would be nice to see how the heap profile reacts to user actions. I imagine a scrolling graph of the last minute or so of time. Does such a thing exist? would writing one be possible without modifying ghc? it seems you can poll the .hp file and update the graph, but i have not looked into the format of .hp files to see if this is plausable. any thoughts?
