pyramid_metrics 0.1.2

Performance metrics for Pyramid using StatsD

Performance metrics for Pyramid using StatsD. The project aims at providing ways to instrument a Pyramid application in the least intrusive way.

• PyPI: https://pypi.python.org/pypi/pyramid_metrics

• Bitbucket: https://bitbucket.org/Ludia/pyramid_metrics

Installation

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

$ pip install pyramid_metrics

Setup

Once pyramid_metrics is installed, you must use the config.include mechanism to include it into your Pyramid project’s configuration. In your Pyramid project’s __init__.py:

config = Configurator(.....)
config.include('pyramid_metrics')

Alternately you can use the pyramid.includes configuration value in your .ini file:

[app:myapp]
pyramid.includes = pyramid_metrics

Usage

Pyramid_metrics configuration (values are defaults):

[app:myapp]
metrics.host = localhost
metrics.port = 8125

metrics.prefix = application.stage

metrics.route_performance = true

Currently implemented

• Collection utility as a request method

• Ability to send metrics per Pyramid route

• Simple time marker mechanism

• Simple counter

TODO

• Full StatsD metric types

• Extensions for automatic metrology (SQLAlchemy, MongoDB, Requests…)

• Whitelist/blacklist of metrics

• Time allocation per subsystem (using the time marker mechanism)

Considerations

• The general error policy is: always failsafe. Pyramid_metrics should NEVER break your application.

• The DNS resolution is done during configuration to avoid recurring latencies.
