Multiple Collectors

• MSPs have collectors installed on various customer's sites.
• Collectors also act as a dependency so if a site goes down and takes the collectors down too, you don't get all the devices at that site to send tons of alert notifications.
• Remote Access via collector proxy might help gain access if site-to-site connection is down.

Automatic failover in case of a system outage. If a collector doesn't report in to the LM platform for 3 minutes, its tasks can be reassigned to a different collector. This can be done through Auto-Balanced Collector Groups or dedicated failover Collectors. 

Also, for ABCGs if one Collector surpasses a defined threshold of instance count, i.e. too much load, the system will automatically reassign devices to a different Collector to balance the load. It's not actual load balancing, but more like automatic overload rectification.
