(I forgot to announce v0.1 so this is a combined announcement.) I'm proud to announce the ekg [1] library. The library lets you remotely monitor any running Haskell program, using your web browser or an automated monitoring program. The library lets you monitor garbage collector and memory usage statistics (similar to what's provided by +RTS -s, but live), but also lets you defined your own counters that you can update from within your program.
