uwsgitop
========

``uwsgitop`` is a top-like command that uses the uWSGI Stats Server to
monitor your uwsgi application.

To use uWSGI Stat Server simply use the ``stats`` option followed by
a valid socket address, for example::

    uwsgi --module myapp --socket :3030 --stats /tmp/stats.socket

To start monitoring your application with ``uwsgitop`` call it with
the socket address like so::

    uwsgitop /tmp/stats.socket

If you want the stats served over HTTP you will need to add
the ``stats-http`` option in uWSGI::

    uwsgi --module myapp --http :3030 --stats :3031 --stats-http

You'll now need to call uwsgitop as::

    uwsgitop http://127.0.0.1:3031

Installation
------------

::

    pip install uwsgitop

Usage
-----

To display async core statistics (e.g. when using gevent) or to switch between
core statistics display mode, press ``a``. To refresh the screen super fast press ``f``,
and to quit, press ``q``.

Colors
------

Lines would be displayed in different colors:

- default console text color, if the worker is idle
- ``green``, if the worker is busy
- ``magenta``, if the worker is in ``cheap`` mode
- ``yellow``, if the worker is handling an uwsgi signal
- ``blue``, if the worker is ``suspended``


Remember to enable ``memory-report`` in your uwsgi configuration to see how
much memory resources your uwsgi processes are consuming.
