send timing and exception stats to riemann

Project description

Introductory blog post:

This library is provided to allow timing and exception reporting of python functions using



pip install riemann_wrapper



python install


Provide a metric name and a bernhard client for timing:

import bernhard
from riemann_wrapper import wrap_rieman, riemann_wrapper

riemann = bernhard.Client()

@wrap_riemann("cpu-intensive-task", client=riemann)
def do_something_cpu_intensive():
   # [...]

Call options:

The following keyword args may be passed to wrap_riemann:

  • client: instance of bernhard.Client to send events with

  • tags: tags to attach to riemann events

  • host: override hostname for the event

Alternately, a new wrapping function can be created by calling riemann_wrapper like-so:

import bernhard
from riemann_wrapper import wrap_riemann, riemann_wrapper

riemann = bernhard.Client()
my_wrapper = riemann_wrapper(client=berhard.Client(), prefix="myapp.")

def do_something_cpu_intensive():
   # [...]

The following keyword args may be passed to riemann_wrapper:

  • client: instance of bernhard.Client to send events with

  • global_tags: tags present in all sent events. Default: ['python'].

  • host: override hostname for all events. Default: None.

  • prefix: prepend given string to all event services. Default: python.

  • exception_state: state sent for exceptions. Default: 'warning'.

  • send_exceptions: boolean or callable that takes an exceptions as a parameter and returns a boolean to specify whether to send that particular exception to riemann. Default: True.
