Installing Monit Using Distribution Packages M/Monit is a web interface that allows you to manage all of your Monit instances. Monit is the agent that must be installed locally on each server you wish to monitor. Monit is made out of two components: Monit and M/Monit.

It is completely free and installation is a breeze. By convention, 0 means the program exited normally. In the example above, Monit will raise an alert if the exit value is different from 0. However, if you are not running a cPanel server, you can use Monit, a lightweight system monitoring and error recovery tool for Linux/Unix servers. 2 Answers Sorted by: 2 Its a quite late answer, nevertheless I find it important since it causes some misunderstanding (so I was misleaded) You dont need to escape a single quote character. Monit will execute the program periodically and if the exit status of the program does not match the expected result, Monit can perform an action.

On cPanel servers, there is a process named TailWatch that monitors log files and takes the appropriate action if a service fails. That monit configuration file is in the conf-available and not the conf-enabled. This probably is not used but in case Z-Way does start to spawn child processes if it gets out of hand, it will eventually get restarted. The eighth line would be where a bunch of children processes have been spawned. So this setting should fit what your system has and where your z-way process currently uses for memory usage. My Pi's have 8GB of RAM, so that amount of memory use could be achieved. If you have a Pi with 512MB of RAM, that would not be a valid configuration setting since it could never be reached. Note you must have the Monit HTTP interface enabled for these commands to work. monit monitor mysql or monit monitor all. If a service has become unmonitored you can re-enable monitoring with e.g. 800.0 MB is a lot of memory and Z-Way doesn't use anywhere close to that which is why I also used that value, it would be well outside the norm and clearly an indication of something gone awry. 52.6k 19 162 211 Add a comment 2 Answers Sorted by: 7 Monit includes commands to enable and disable monitoring of all or specific services. You can set the CPU usage to whatever you like or feel is appropriate for your setup. The sixth line is if the CPU usage is > 80 for five cycles (my cycle is 15 seconds) then restart the process. Monit reconnects PPP and restarts lora-packet-forwarder for you automatically. This means there is obviously an issue that require intervention on your part. The fifth line is if it restarts and then has to keep restarting as it keeps failing, then timeout. The fourth line is checking reachability on port 8083 using http and if a connection cannot be established it is viewed as failed and to restart the process.
#LINUX MONIT EXAMPLES HOW TO#
The start and stop commands are telling it how to start and stop the process. The first line is telling it of the process and where the pid file is. If loadavg(5min) greater than 3 for 8 cycles then stop If totalmem > 800.0 MB for 5 cycles then restart Then type admin for the user’s name and monit for the password. Just navigate to the following URLs: http: //localhost:2812. Now, you are ready to access the Monit web interface.
