Python library to write Nagios plugins.

Project description

PyNagios is a simple Python library meant to make writing Nagios plugins much easier. Nagios plugins have quite a few guidelines to adhere to, and PyNagios provides helpers to make this easy.

Install

To install, simply use pip or easy_install:

pip install pynagios

Documentation

Documentation for the latest version can always be found at http://kiip.github.com/pynagios/latest.

Features

The core features supported by PyNagios:

  • Parsing command line arguments such that the standard expected arguments (such as -H, -w, -c) are accepted.
  • Returning proper POSIX exit code based on status.
  • Parsing Nagios range formats (such as “@10:20”, “~:50”, “10”, etc.)
  • Outputting status and message.
  • Outputting performance data.

Example

What all these features result in is a concise, simple, and guidelines-compliant Python-based Nagios plugin:

from pynagios import Plugin

class UserCheck(Plugin):
    """
    Nagios plugin to check how many users are logged into this
    machine.
    """

    def check(self):
        # Get the number of logged in users, for now we hardcode
        users = 27

        # Build a response and exit. This `response_for_value` automatically
        # creates a response with the proper status given the value and the
        # warning/critical ranges passed in via the command line.
        response = self.response_for_value(users, "%d users" % users)
        response.set_perf_data("users", users)
        response.set_perf_data("another metric", 27, "MB")
        return response

if __name__ == 'main':
    # Build the plugin instance and run it. This will also parse
    # command line arguments by default.
    UserCheck().check().exit()

While the above example subclasses Plugin, you’re of course welcome to simply call Plugin`s methods directly and build a ``Response` yourself.
