MONIT - UNIX Systems Management
Monit is a utility for managing and monitoring processes, programs, files,
directories and filesystems on a Unix system. Monit conducts automatic
maintenance and repair and can execute meaningful causal actions in error
Monit logs to syslog or to its own log file and notifies you about error
conditions via customizable alert messages. Monit can perform various
TCP/IP network checks, protocol checks and can utilize SSL for such checks.
Monit provides an optional http(s) interface and you can use a browser to
access the Monit program.
System requirements
* Memory and Disk space
A minimum of 1 megabytes RAM are required and around 500KB of free disk
space. You may need more RAM depending on how many services Monit should
* ANSI-C Compiler and Build System
You will need an ANSI-C99 compiler installed to build Monit. The GNU C
compiler (GCC) from the Free Software Foundation (FSF) is recommended. In
addition, your PATH must contain basic build tools such as make.
Monit utilize the GNU auto-tools and provided the requirements above are
satisfied, building Monit is conducted via the standard;
make install
This will install Monit and the Monit man-file in /usr/local/bin and
/usr/local/man/man1 respectively. If you want another location than
/usr/local, run configure with the prefix options, like so: ./configure
Use ./configure --help for build and install options. By default, Monit is
built with SSL, PAM and large file support. You may change this with the
--without-<xxx> options to ./configure. E.g. --without-ssl, --without-pam
or --without-largefiles.
After you have built Monit you can simply start the monit program from the
build directory to test it. Monit will use the monitrc control file located
in this directory for it's configuration. The file is setup to start
Monit's http server so you have something interesting to look at; After you
have started monit, point your browser to and log in
with the username admin and password monit.
Once started, monit will run as a background process. To stop monit, use
monit quit. To run monit in the foreground and in diagnostic mode, start
monit with the -Iv options. In diagnostic mode, monit will print debug
information to the console. Use ctrl+c to stop monit in diagnostic mode. To
see all options for the program, use monit -h.
Copy monitrc in the build directory to $HOME/.monitrc or if you plan to run
Monit as root, to /etc/monitc. Use this file as a starting point to write
your own configuration file for Monit.
Please use `man monit' for an in-depth documentation of the program. More
documentation can be found at
Questions and support
If you have questions or comments about the software or documentation
please subscribe to the Monit general mailing list and post your questions
Thanks to the Free Software Foundation (FSF) for hosting the mailing list.
The design of libmonit was inspired by principles put forth by David R.
Hanson <> in his excellent book "C Interfaces and
Implementations". You can learn more about this book here
