Sentinel provides scalability for data processing of flows and streaming telemetry received by one or more Minions. It also supports thresholding for streaming telemetry if you are using OpenNMS Newts. If you need to scale processing capacity for flow and/or streaming telemetry, you need Sentinel.

In most cases, you can disable adapters and listeners in Horizon that are also run by a Sentinel instance.
