I’ve been working with app engine for quite some time, I know that there is appstats but those only show datastore/memcache and other not related to actual memory usage stats.

I’ve tried to integrate with AppTrace (with all the components latest versions) but I can’t continue, since I get this error:

ImportError: dlopen(../apptrace/guppy/sets/setsc.so, 2): Symbol not found: __PyLong_AsScaledDouble
Referenced from: ../apptrace/guppy/sets/setsc.so
Expected in: flat namespace

So my question is:
what is the best way (on latest appengine sdk) to profile/monitor memory/catch memory leaks and other python-memory related stuff (either on local or Google server)?

btw, we use Python 2.7 and we’re working on Mac OS X (10.7.4)

  api_cpu_ms =  293.33 (api_datastore_v3 = 100%, other =   0%)

    also you can use memcacheApi and other staf
