Slowjam: Application Tracing For Python

Slowjam is an easy to use application tracer for python.

Listen to this:

>>> import requests

>>> from slowjam.trace import span
>>> from slowjam.context import slowjam_context

>>> slowjam_context.start('my_application', extras={'http': True})

>>> with span('listen', extras={'deylay': 3}):
>>>     resp = requests.get('https://httpbin.org/delay/3')

>>>     with span('request.origin'):
>>>         origin = resp.json().get('origin')
>>>         origin.split('.')

>>> profile = slowjam_context.stop()
>>> if profile:
>>>     print ''
>>>     print unicode(profile)
>>>     print ''

       time   exec time event
----------- ----------- ------------------------------
       0 ms             + my_application [http=True]
       0 ms             | + listen [deylay=3]
    8039 ms (+    0 ms) | | = request.decode
            (+ 8039 ms) | +
            (+ 8039 ms) +

Slowjam makes it easy to start getting feedback quick, but with some extra effort it seamlessly integrates with other monitoring tools such as statsd, graphite, and logstash.
