Nagios Plugins

  • For instructions on installing these plugins for use with Nagios, 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 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 for developer discussions.

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

  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 Nagios is installed (default is /usr/local/nagios), and replace SOMEURL with the path used to access the Nagios 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

Testing With libtap

  1. The nagios-plugins source includes a perl testing suite. the libtap library and headers are included with the source. Configure with:

    ./configure --enable-libtap

    Note: "--enable-extra-opts" used to be required as well, but is no longer required as it is a default configure option.

  2. Make and then make test:

    make make test

  3. Testing is pseudo intelligent and will try to autodetect which plugins to test. You may need to look at the REQUIREMENTS doc as to what dependencies are required to satisfy the test.

    Additionally, default and user supplied (at runtime) testing parameters are saved in the file:


    If you need to change any testing parameters, edit them in this file or just remove the line to force the test to re-prompt you for input.
