Open command terminal or access the server via SSH.

Steps to Munin Monitoring on Ubuntu 20.04 LTS Linux. #allow localhost # allow localhost to connect to the server andĪllow admin:monit # require user ‘admin’ with password ‘monit’Īllow # allow users of group ‘monit’ to connect (rw)Īllow readonly # allow users of group ‘users’ to connect readonly #use address localhost # only accept connection from localhost Set the location of the Monit id file which stores the unique id for the Monit instance Set syslog logging with the ‘daemon’ facility. bionic-updates (gnome): Process viewer and system resource monitor for GNOME. Start Monit in the background and check services at every one minute bionic (18.04LTS) (gnome): Process viewer and system resource monitor for GNOME. You must set this variable to for monit to start. Once you don't have any syntax errors you need to enable this service by changing the file /etc/default/monit. The Default Port Number of Monit is 2812. After configuring your monit file you can check the configuration file syntax using the following command.
Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations. start program = "/usr/bin/systemctl start my_unit").Monit is a utility for managing and monitoring, processes, files, directories and devices on a UNIX system. User binding, restarts, pidfile, and "start-on-boot" can then be managed through systemd (eg. In fact, it's not even hard to convert your script into a systemd unit. Nothing fancy here ) echo $$ > /run/launch.pid It simply writes the current process ID to the pidfile. This quick'n'dirty way also needs an additional line for your launch_example.sh to write the pidfile (pidfile matching should always be preferred over string matching) - it could be just the first line after she shebang. Stop program = "/bin/bash -c 'kill $(cat /run/launch.pid)'" Start program = "/bin/bash -c 'nohup /home/ubuntu/launch_example.sh &'" After configuring your monit file you can check the configuration file syntax using the following command. check process launch_example with pidfile /run/launch.pid So if you want to monitor your long running executable, you have to wrap it. Monit is just for monitoring and is not some kind of supervisor/process manager.
