check_xmppng - check plugin for XMPP

This program implements a nagios check plugin for XMPP servers implementing the XMPP protocol as specified in RFC 6120.

The program implements the following features:

  • check client to server (C2S) as well as server to server (S2S) ports
  • check XMPP servers on IPv6 and IPv4 addresses
  • support STARTTLS as specified in RFC 6120 section 5.
  • check the validity of the server certificate presented by the XMPP server

The plugin has been implemented because of insufficiencies in check_ssl_cert and the existing check_xmpp.

Maximum acceptable timeouts as well as minimum acceptable number of days the server certificate needs to be valid can be specified as command line parameters. For a full list of parameters see the Usage section below.

Dependencies

The program is implemented in Python 3 and uses the following libraries besides the Python standard library:

  • defusedxml to sanitize XML from the XMPP server
  • nagiosplugin to take care of the nagios plugin interface boilerplate code

The software has been developed and tested with the following versions:

  • Python 3.4.2
  • defusedxml 0.4.1
  • nagiosplugin 1.2.2

  --no-check-certificates
                        do not check whether the XMPP server's certificate is
