Stop program = "/bin/systemctl stop rvice" Start program = "/bin/systemctl start rvice" with timeout 15 seconds Service solution and what action should perform check process apache2 with pidfile /run/apache2/apache2.pid To perform when the application is not reachable. Take proactive solution, we can mention the service location also desire action Shell script, everything after a hash is a comment, the monit ignores Will get you up and running with monit configuration snippets. This host check is taken from these monit configuration examples, a useful page that If cpu usage (wait) > 85% for 5 cycles then alert If cpu usage (system) > 20% for 5 cycles then alert If cpu usage (user) > 60% for 5 cycles then alert If swap usage > 20% for 5 cycles then alert If memory usage > 85% for 5 cycles then alert # so total CPU usage can be more than 100% # multi-core systems can generate 100% per core Add the following to your monitrc file: # Test CPU usage including user, system and wait. We’ll monitor some of our server’s core metrics, such as cpu usage and swap This allows to access monit via WebUI with port 2812, you can restrict the connection with selected IP’s but mentioning the IP instead of 0.0.0.0 Use address localhost # only accept connection from localhostĪllow 0.0.0.0/0.0.0.0 # allow localhost to connect to the server andĪllow admin:monit # require user 'admin' with password 'monit' Perform disable and enable monitoring for existing configured stuffs. It have WebUI to check the service or system or port status and also you can Special logfile just for monit, as opposed to syslog.” Should set how frequent Monit should perform the test/check and whenever it findsĪnything wrong it do the action mentioned in the config file, either alert orĬheck all the services and ports etc I’ve defined in this config fileĮvery 120 seconds or two minutes.” The second line means “please log into a Where to mention? In Monitrc file you can see file value you Process runs periodically as per configuration, do the defined tasks and go toīe sleep mode). # monit status # show some basic system information It willĪnd check what’s going on by typing: # monit # this will launch the monit daemon rw- 1 root root 28993 J/etc/monit/monitrcĬonfiguration file to make sure your configuration is correct. Once you’ve added epel repository, install package by running the following commands as below On RedHat/CentOS/Fedora/ # yum install monit On Ubuntu/Debian/Linux Mint # apt-get install monit Configurationįind the config file on following location and you can configure based on your Another cool extra features like service management and file-hash checking and is easy to use.īy default, if package not available on system base repositories, you need to add and enable third party epel repository (# yum install epel-release) to install monit package under your RHEL/CentOS.One of the big advantages is, monit reacts when things go wrong like restarting the services, running any custom scripts, alert via mail, teams or slack etc.Keep check the service status and make sure services are up and running.Monit keeps its own log file and alerts about any critical error conditions and recovery status. This tools able monitor and manages server process (Like Nginx, Apache, MySQL, FTP, telegraf etc), files, directories, checksums, permissions, filesystems in Unix/Linux based systems automatically.Īlong with this, this is capable monitor remote and local TCP/IP ports, Server protocols and ping, which will keep you alert incase if any service unavailable and this helps you to keep your up and running always. Today we want to discuss yet another useful monitoring tool for the system/Linux administrators called Monit.
