(Optional For Fans Of CLI) Additionally, Monit offered a web interface for viewing the status of processes and services. Before installing it, CentOS/RHEL users must activate the epel repository in their system.ĭebian and Ubuntu sudo apt-get install monitĪrch Linux pacman -S monit Enable Monit Web Interface In most Linux varieties, Monit may be quickly installed using the package manager. ![]() Systemįinally, Monit can be used to monitor localhost’s system resources in general, including average load, memory consumption, and CPU usage. This means you can do any kind of check using Monit, for which you can write a script. However, you can also use Monit to check a program’s exit value and take action or send an alert if it signals a problem. Like cron, Monit may be used to test programs or scripts at predetermined intervals. You can set Monit to send any data and test the server’s response even if the server does not support a protocol. ![]() Protocol-level network tests are possible Monit includes built-in tests for the major Internet protocols, including HTTP, SMTP, and others.

If a file’s md5 or sha1 checksum should change, you can receive a notification or take action. You can utilize this for security purposes as well. Monit can watch these elements for timestamps, checksums, or size changes. Monit may also keep track of localhost files, directories, and filesystems. Sendmail, sshd, apache, and MySQL are a few examples of daemon processes that can be monitored with the help of monit, such as those launched from /etc/init/ at system startup. Monit can be used to keep an eye on daemon processes and other similar software operating locally. Process attributes, such as how much memory or CPU time a process is using, can also be tracked by Monit. Similarly, if apache is consuming too many resources (for example, if a DoS assault is underway), Monit can stop or restart apache and send you a warning message. For instance, if Sendmail is not operating, Monit can restart Sendmail automatically. ![]() If an error occurs, Monit can take action.
