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 `NEWS` 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:
* <https://www.nagios-plugins.org/>
Send an email to <[email protected]> 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 <[email protected]> for developer discussions.
For patch submissions and bug reports, please use the appropriate resources
at:
* <https://github.com/nagios-plugins>
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.nagios-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 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:
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 <[email protected]>.
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:
/var/tmp/NPTest.cache
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.

Static Analysis Tools
--------------
Coverity is a tool used to statically analyze C\C++ code and determine
possible vulnerabilities, bugs, and usage errors. Nagios-Plugins considers
these items to be extremely important for proper code coverage and
longevity. It should be noted that a "Passed", does not mean that all
Coverity reported issues have been resolved, instead that the latest build
submitted did not have any newly found issues, and may or may not have
eliminated previously found issues. We use several testing processes that
end with a submission to Coverity on each successful build. This means that
you will often see this badge pending or with new issues found as new
features, pull requests, and github issue resolutions submitted in other
branches will reflect on the badge displayed on the master branch. However,
the master branch and therefore any releases will not be updated without a
current clean scan from Coverity. With that said, below you can find the
current state of the Nagios-Plugins project per Coverity's view.
