So if your python starts with pid 100 and got killed anyhow, but another process takes pid 100, your Monit will not notice it and thinks everything is fine.Python API and shell utilities to monitor file system events.Ī simple program that uses watchdog to monitor directories specifiedĪs command-line arguments and logs events generated: import sys import time import logging from watchdog.observers import Observer from watchdog.events import LoggingEventHandler if _name_ = "_main_" : logging. Monit has no connection between pid-file and binary. The biggest flaw with this approach would be the possible reuse of pids. If 3 restarts within 5 cycles then unmonitor Stop program = "/monit/MyProgram-kill" as uid MyNonRootUserHere Start program = "/monit/MyProgram-daemonize" as uid myNonRootUserHere You can use check process then: check process MyProgram pidfile "/tmp/MyProgram.pid" I used kill -SIGTERM, because kill -SIGKILL or kill -9 are evil ) You might have to adjust this.I used /tmp/ instead of /run for permission reasons.There is something unusual happening if status "/tmp/MyProgram.pid"Īnd another one ( /monit/MyProgram-kill): #!/usr/bin/env bash.You need to daemonize your script for that. I think that you need to go for check process in this case. You are trying to use check program to daemonize your application. You can then, based on status-code, contents, etc., react to the result/output of the execution. Example: du -hd1 will run, create an output, and exit. This program should exit after some time and Monit reacts on how all that was going. Example: systemctl start nginx will not run a nginx in foreground (and block your bash), but will start a daemon in background (that keeps running even after you killed your session).Ī program is a binary executed and controlled by Monit. It can, however, interact with the daemon-izer. Monit does not really control those applications. There is a significant difference between a process and a program in Monit:Ī process is a binary running in the background - a daemon (like an HTTPd, a DB Server, etc.).Ī process is not run by Monit. If the program is running and for some reason it stops with an exit code other than 0 the monit will not restart it (see my configuration below). (sorry for the long answer in advance ^^)īut when I use check program Monit will not automatically start it.
