Before making the release I thought it would be an idea to ask people what other features people would find useful or performance tuning. So if you have any suggestions please do let us know!
Is it available in a branch somewhere to try out?
There are three parts to it:
- some patches to GHC to generate the log files. The patches are not yet in, but I hope to get them in in the next couple of weeks.
Just as a meta-point, it makes a *lot* of sense for the runtime to support proper logging -- it's practically a microkernel after all, so logging makes as much sense for GHC's rts as it does for regular kernels. Now we just need a /proc for the rts, so I can peek at GC stats live.
- a Haskell library for parsing the log files. This will be up on Hackage soon. You can use this to write your own analysis tools, visualisers, or whatever.
- The ThreadScope viewer itself, which will also be up on Hackage as soon as its ready.
So we fully intend to get this out there ASAP, although until GHC 6.12 is released you will need to use a GHC snapshot to generate the log files.
Sweet. This should have many many applications for work projects ... "attach a viewer to a remote Haskell server to see what's it's up to"... "heartbeat monitoring of the rts" ... -- Don
