Python profiler endpoints like Go's net/http/pprof.

Project description


pypprof adds HTTP-based endpoints for collecting profiles from a running Python application a la Go's net/http/pprof.

Under the hood, it uses zprofile and mprofile to collect CPU and heap profiles with minimal overhead.


Add profiling endpoints to an application

Register the profiling endpoints in your application:

from pypprof.net_http import start_pprof_server


Fetch profiles from your running application

Fetch a 30s CPU profile, and view as a flamegraph:

$ go tool pprof -http=:8088 :8081/debug/pprof/profile

Fetch a heap profile:

$ go tool pprof :8081/debug/pprof/heap

Dump stacks from your application:

$ curl localhost:8081/debug/pprof/thread?debug=1


pypprof is compatible with Python >= 2.7. Memory profiling is only available by default in Python >= 3.4. To enable memory profiling in earlier Pythons, you must patch Python and manually install mprofile.


Pull requests and issues are welcomed!
