If bamboo (slow starting web app) is down for 3 minutes in a row, restart, BUT only if a restart script is not already running. Then exec "/bin/bash -c 'ps -ef | grep -v "$$" | grep -v "grep" | grep restartBamboo.sh >/dev/null 2>&1 if then /opt/monit/scripts/restartBamboo.sh fi'" It also comes with a web interface to monitor your system. It works by using an intermediate script that acts as flag to indicate monit is already taking action from the last failure. Monit is a free and open source service monitoring application which can perform various event-based actions. Monit is a server monitoring program that can check the processes running on your system to ensure that they’re always online and operating within reasonable CPU and memory limits. This prevents waiting too long between checks, which combined with slow start is a much larger impact to customers. Start program = "/etc/init.d/httpd start" with timeout 90 secondsĪ member of my team came up with a rather clever solution that allows monit to check frequently (every minute), but once it has attempted to restart the service (which takes ~10 minutes) it will wait a specified grace period before attempting to start again. Or if you're experiencing a slow startup, you can extend the timeout in the service start command: check process apache with pidfile /var/run/httpd.pid Monitor the health and performance of websites, servers, networks. monit is a utility for managing and monitoring processes, files, directories and filesystems on a Unix system. check process resque with pidfile /var/run/resque.pid Site24x7 offers both free & paid monitoring services for your entire IT environment. Or you can leverage the cron-style checks. (It is at the discretion of the Program Supervisor to alter this schedule). The minimum timeout is 1 minute, and the process that reaps critical services runs every 30 seconds, so it may take slightly longer than the configured timeout. Start program = "/etc/init.d/dynamo start" Information on monitoring and inspections of licensed child care agencies. Implement a criminal monitoring program to. Monit conducts automatic maintenance and repair and can execute meaningful. < 60 seconds) but allow some services to take its time to start,Ĭheck process dynamo with pidfile /etc/dynamo.pid every 2 cycles For most companies, criminal checks on candidates or contractors are a standard part of pre-engagement. Monit is a small Open Source utility for managing and monitoring Unix systems. So if we want to keep the poll-cycle low (i.e. Or from the examples section: Some servers are slow starters, like for example Java based Application Servers. See SERVICE POLL TIME in the Monit documentation.Īn example for your Resque program would be to check on a different number of cycles: check process resque with pidfile /var/run/resque.pid You can check a specific service on a different interval than the default.
