README

This bundle try to solve the following problem

How to be sure that a given service is running from 7am to 7pm ?
If the service fall it must be restarted. And how do be sure that
a service is NOT running from 7pm to 7am ? If the service is
running it must be stopped.

We can do it with cron but that need a few lines :

• to start the service,
• stop it at the end of day,
• check every minute from 7am to 7pm that the service is running,
• then check every minutes from 7pm to 7am that the service is not running.

If there is only one service like that, it's ok. But when there is more, it become hard to maintain.

Installation

composer require kinulab/process-monitoring-bundle:^1.0

add in your app/AppKernel.php :

    public function registerBundles()
    {
        $bundles = [
            // ...
            new Kinulab\ProcessMonitoringBundle\KinulabProcessMonitoringBundle(),
        ];
    }

How to use it ?

Register a symfony service that implements the Kinulab\ProcessMonitoringBundle\Service\ServiceDescriptorInterface.

Tag this service as monitored.service.

Then ensure yourself that the bin/console monitor:services command is constantly running. For that, you can use cron, monit, supervisord or whatever you prefer to use.
