A WSGI middleware to monitor performance in production systems





iscool_e.pynba is a WSGI Middleware for Pinba. It allows realtime monitoring/statistics server using MySQL as a read-only interface.

It accumulates and processes data sent over UDP by multiple PHP processes and displays statistics in a nice human-readable form of simple "reports", also providing read-only interface to the raw data in order to make possible generation of more sophisticated reports and stats.

Users also can measure particular parts of the code using timers with arbitrary tags.

Why another statistics manager ?

Because Pinba rocks!

At IsCool Entertainment, we already use Pinba for monitoring our PHP based applications.


This library relies on Pinba, Protobuf and Werkzeug. You will need to install theses packages before using Pynba.

The installation process requires setuptools to be installed. If it is not, please refer to the installation of this package.


 git clone
 python install


Says that your main WSGI application is:

def app(environ, start_response):

Import the pynba decorator, and decorate your main app with it:

from iscool_e.pynba import monitor

@monitor(('', 30002))
def app(environ, start_response):

Each time the app will be processed, a new UPD stream will be sent.

Eventualy, you can use timers to measure particular parts of your code. For it, just import the pynba proxy, and use it to create new timers:

from iscool_e.pynba import pynba

timer = pynba.timer(foo="bar")

Some use cases are available on src/examples/

Differences with PHP extension

About the data sent:

- ru_utime and ru_stime represent the resource usage for the current process, not the shared resources.

- document_size cannot be automaticaly processed with the current WSGI specification. You are able to set manually this value like this:

- pynba.document_size = [YOUR VALUE]

- memory_peak also is currently not implemented. Like the previous data, you can set manually this value like this:

- pynba.memory_peak = [YOUR VALUE]

About timers:

- The Python version permites multiple values for each timer tags. Just declare any sequences, mapping or callable. This example:

 pynba.timer(foo='bar', baz=['seq1', 'seq2'], qux={'map1': 'val1'})

 Will populates 4 values for 3 tags in the Pinba database:

 ('foo', 'bar'),
 ('baz, 'seq1'),
 ('baz, 'seq2'),
 ('qux.map1', 'val1')
