repoze.profile 0.5

Installation

Install using setuptools, e.g. (within a virtualenv):

$ easy_install repoze.profile

Configuration via Python

Wire up the middleware in your application:

from repoze.profile.profiler import AccumulatingProfileMiddleware
middleware = AccumulatingProfileMiddleware(
               app,
               log_filename='/foo/bar.log',
               discard_first_request=True,
               flush_at_shutdown=True,
               path='/__profile__'
              )

The configuration options are as follows:

- ``log_filename`` is the name of the file to which the accumulated
  profiler statistics are logged.

- If ``discard_first_request`` to true (the default), then the
  middleware discards the statistics for the first request:  the
  rationale is that there are a bunch of lazy / "first time"
  initializations which distort measurement of the application's
  normal performance.

- If ``flush_at_shutdown`` is true (the default), profiling data will
  be deleted when the middleware instance disappears (via its
  __del__).  If it's false, profiling data will persist across
  application restarts.

- ``path`` is the URL path to the profiler UI.  It defaults to
  ``/__profile__``.

Once you have some profiling data, you can visit path in your browser to see a user interface displaying profiling statistics (e.g. http://localhost:8080/__profile__).

Configuration via Paste

Wire the middleware into a pipeline in your Paste configuration, for example:

[filter:profile]
use = egg:repoze.profile#profile
log_filename = myapp.profile
discard_first_request = true
path = /__profile__
flush_at_shutdown = true
...

[pipeline:main]
pipeline = egg:Paste#cgitb
           egg:Paste#httpexceptions
           profile
           myapp

Once you have some profiling data, you can visit path in your browser to see a user interface displaying profiling statistics.
