Meridian Instance Management
An instance is a single implementation of OpenNMS Meridian. You need a separate Meridian instance for each licence type: Appliances or Time Series DB.
An "Appliances" Meridian instance indicates how a Minion Appliance connects to your Meridian instance by specifying connectivity information (for example, message broker details) and configuration information (traps, syslog, telemtryd).
A "Time Series DB" instance provides the key required to activate the Time Series DB feature.
