Monit is a free open source 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 situations.
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 monitor.
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.
To checkout Monit source code, use
git clone https://firstname.lastname@example.org/tildeslash/monit.git.
If you build Monit from the git repository you should call
./bootstrap first, before continuing with the installation steps below.
Monit utilize the GNU auto-tools and provided the requirements above are
satisfied, building Monit is conducted via the standard;
./configure make 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 and specify the install directory.
Use ./configure --help for build and install options. By default, Monit is built with SSL, PAM and large file support. You can change this
with the --without-<xxx> options to ./configure. For instance, --without-ssl, --without-pam or --without-largefiles.
If you need to build your own Monit source release package, follow these steps.
make cleanall ./bootstrap ./configure make dist
This will produce a
monit-x.y.tar.gz file in the current directory which can be used for distribution. Note that we do not use make distclean which is the convention, instead we use
make cleanall to reset the Monit build directory, including libmonit, to pristine condition for a source release. Before a release you might also want to run unit-tests in libmonit. I.e. cd libmonit; make verify;.
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
http://127.0.0.1:2812/ and log in with the username
admin and password
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
monitrc in the build directory to ~/.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.
man monit for an in-depth documentation of the program. More documentation can be found at Monit's web-site
