WMI based plugin

The class NagiosPluginWMI that inherits from NagiosPlugin is responsible to init a plugin based on WMI.

She will provides new attributes and methods in order to query a host using WMI.

If you show the help with --help, you will see extra arguments provided by the class. It uses the same mechanics as we saw in Creating a new plugin, the basics section. It overrides NagiosPlugin.define_plugin_arguments() to define new arguments and NagiosPlugin.verify_plugin_arguments() to do arguments checking.

Getting started

import logging
from monitoring.nagios.plugin import NagiosPluginSNMP

logger = logging.getLogger('plugin')

plugin = NagiosPluginWMI()
system_infos = plugin.execute(r'SELECT * FROM Win32_OperatingSystem')

for attribute in system_infos:
   print "Hostname: ", attribute['CSName']

• plugin is a NagiosPluginWMI instance.
• system_infos is the result of NagiosPluginWMI.execute() that returns a list of dict that contains the attributes (WMI columns) as the key and the associated value (attribute['CSName']).

If you enable DEBUG mode (with --debug), you will have the result of the query:

[{None: ['5.2.3790', 'C:\\WINDOWS'],

 'BuildNumber': '3790',

Notes

• Some columns do not have a name, so the key is None.
