Lorenz Kästle bc2720abdd check_smtp: certificate check is no longer opt-in
This is a breaking change.
Testing whether a TLS certificate is still valid (expiration wise)
is now the default in check_smtp.
The reasoning is, that in most scenarios an expired certificate
will effectively mean that the service is not working anymore due to
the refusal of other software to talk to it.

There is a new cli parameter though to explicitly ignore that.

Monitoring Plugins

  • For instructions on installing these plugins for use with your monitoring system, see below. In addition, generic instructions for the GNU toolchain can be found in the INSTALL file.

  • For major changes between releases, read the NEWS file.

  • For information on detailed changes that have been made or plugins that have been added, read the ChangeLog file.

  • Some plugins require that you have additional programs or libraries installed on your system before they can be used. Plugins that are dependent on other programs/libraries that are missing are usually not compiled. Read the REQUIREMENTS file for more information.

  • Individual plugins are self-documenting. All plugins that comply with the basic guidelines for development will provide detailed help when invoked with the -h or --help options.

You can check the latest plugins at:

Send an email to help@monitoring-plugins.org for assistance. Please include the OS type and version that you are using. Also, run the plugin with the -vvv option and provide the resulting version information. Of course, there may be additional diagnostic information required as well. Use good judgment.

Send an email to devel@monitoring-plugins.org for developer discussions.

For patch submissions and bug reports, please use the appropriate resources at:

Installation Instructions

  1. If you are using the Git tree, you will need m4, gettext, automake, and autoconf. To start out, run:

    ./tools/setup
    

    For more detail, see the developer guidelines at https://www.monitoring-plugins.org/doc/guidelines.html.

  2. Run the configure script to initialize variables and create a Makefile, etc.

    ./configure --prefix=BASEDIRECTORY --with-cgiurl=SOMEURL
    

    Replace BASEDIRECTORY with the path of the directory under which your monitoring system is installed (default is /usr/local), and replace SOMEURL with the path used to access the monitoring system CGIs with a web browser (default is /nagios/cgi-bin).

  3. Compile the plugins with the following command:

    make
    
  4. Install the compiled plugins and plugin scripts with the following command:

    make install
    

    The installation procedure will attempt to place the plugins in a libexec/ subdirectory in the base directory you specified with the --prefix argument to the configure script.

  5. There are some plugins that require setuid. If you run make install as a non-root user, they will not be installed. To install, switch to root and run:

    make install-root
    

That's it! If you have any problems or questions, feel free to send an email to help@monitoring-plugins.org.
