6.0 Communication Layer (iSCALE)

The communication layer (iSCALE) connecting all components of the architecture is an encrypted TCP/IP based connection built on a JMS (Java Messaging Service) backbone. With Sentinel 6, an optional SSL proxy has been added to secure the Collector Manager and Sentinel Control Center components if they are installed outside the firewall.

There are two communication options available when installing the Collector Manager:

Either of these options can be selected when installing the Collector Manager. The Sentinel Control Center uses the proxy by default.
