Question

I have a python application that has some performance hiccups. I want to add the garbage collector’s events (especially, when does it get called) to my logs. Is it possible?

thanks.

You can set the Flags, but they get written to stderr.

Available flags are

gc.DEBUG_STATS
gc.DEBUG_COLLECTABLE
gc.DEBUG_UNCOLLECTABLE
gc.DEBUG_INSTANCES
gc.DEBUG_OBJECTS
gc.DEBUG_SAVEALL
gc.DEBUG_LEAK

ALSO

When you are dealing with performance, you might wish to profile your code for exhaustive Loops or Function calls. You can use cProfile or hotshot. More here http://docs.python.org/library/profile.html
