![]() $ sudo monit #You should see the message below in the end# Starting Monit is as simple as running one command. Sudo dnf -y install zlib-devel pam-devel openssl-devel libtool bison flex autoconf gcc make git epel-release Step 2: Install Monit on CentOS 8/Rocky 8/Alma 8/RHEL 8Īfter the dependencies and applications we need have been settled in, let us put our repositories to good use by fetching it and installing it via DNF. Step 1: Update and install necessary packagesīefore we enjoy the delight of Monit, we shall make sure all dependencies have been met by installing the following important packages. We shall fetch the code and install it via epel-repository. Hoping the rendition about this tool suffices, we can go ahead and set it up in our server so that we can see first hand the benefits that accrues once it starts working behind the scenes. Install Monit on CentOS 8/Rocky 8/Alma 8/RHEL 8 In addition, your PATH must contain basic build tools such as make. The GNU C compiler (GCC) from the Free Software Foundation (FSF) is recommended. ANSI-C Compiler and Build System: You will need an ANSI-C99 compiler installed to build Monit.You may need more RAM depending on how many services Monit should monitor. Memory and Disk space: A minimum of 1 megabytes RAM are required and around 500KB of free disk space.Network tests can be performed on a protocol level Monit has built-in tests for the main Internet protocols, such as HTTP, SMTP etc. TCP, UDP and Unix Domain Sockets are supported. ![]() Cloud and Hosts: Monitor network connections to various servers, either on localhost or on remote hosts.Programs and scripts monitoring: Monit can be used to test programs or scripts at certain times, much like cron, but in addition, you can test the exit value of a program and perform an action or send an alert if the exit value indicates an error.This is also useful for security reasons – you can monitor the md5 or sha1 checksum of files that should not change and get an alert or perform an action if they should change. Monit can monitor these items for changes, such as timestamps changes, checksum changes or size changes. Files, Dirs and Filesystems monitoring: You can also use Monit to monitor files, directories and filesystems on localhost.Monit is particularly useful for monitoring daemon processes, such as those started at system boot time from /etc/init/ Processes monitoring: You can use Monit to monitor daemon processes or similar programs running on localhost.System monitoring: Monit can be used to monitor general system resources on localhost such as overall CPU usage, Memory and Load Average.if a DoS attack is in progress) Monit can stop or restart apache and send you an alert message. if sendmail is not running, Monit can start sendmail again automatically or if apache is using too much resources (e.g. Proactive monitoring: Monit can act if an error situation should occur, e.g.Monit gives a display of its prowess in the following ways:
