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 and/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 for 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:


    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:

  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.
