This role will leverage Monit as a process watchdog to manage sensors, topologies, and core services.
Monit can be used to start, stop, or check status of any of the sensors or topologies.
When monitoring is enabled (on by default) if a process dies, it will be restarted.
The Monit web interface is exposed at http://hostname:2812.
The web interface username and password is defined by the monit_user and monit_password variables. These default to admin/monit.
Monit CLI tools can also be used to simplify the process of managing Metron components.
The post-deployment report for Amazon-EC2 provides links to Monit's web interface labeled as ‘Sensor Status’ and ‘Topology Status.’
