Sometimes the simplest tools are the most useful, as proven by the simple watchdog Monit. Its role is to ensure that any given process on a machine is up and running appropriately. For example, a failure occurs in Apache, Monit will help to restart the Apache process. It is very easy to setup and configure and is especially useful for multi-service architecture with hundreds of micro-services. If you are using Monit, make sure to monitor the restarts that it executes in order to surface problems and implement solutions (rather than just restarting and ignoring the failure). You can do this by monitoring Monit’s log files and ensuring that you are alerted to every restart.
