Performance stats logger

Project description

https://travis-ci.org/cjrh/perflog.svg?branch=master https://coveralls.io/repos/github/cjrh/perflog/badge.svg?branch=master https://img.shields.io/pypi/pyversions/perflog.svg https://img.shields.io/github/tag/cjrh/perflog.svg https://img.shields.io/badge/install-pip%20install%20perflog-ff69b4.svg https://img.shields.io/pypi/v/perflog.svg

perflog

Structured logging support for application performance and monitoring data

Demo

""" My Application """

import perflog

def main():
    <All the usual application code goes here>


if __name__ == '__main__':
    perflog.set_and_forget()
    main()

There are several parameters for the set_and_forget method that can be used to change the default behaviour. For example, by default the performance log messages will be written every 60 seconds.

Note: in addition to writing performance data to the log message itself, perflog also adds extra logrecord fields. This means that if you’re using a log formatter that writes out all the fields in some kind of structured format (say, logstash_formatter), you will find that the performance data will also be recorded in those fields and can therefore be accessed in tools like Kibana.

Acknowledgements

perflog uses psutil to obtain all the process-related information. Thanks Giampaolo!
