JET syslog notifications over Mosquitto/MQTT

You can configure JET applications by using the CLI and then enable the applications to subscribe to system log events. The Junos OS Evolved eventd process sends system log notifications to the event broker. The broker then sends the notifications formatted as JSON messages to the JET application over the Message Queuing Telemetry Transport (MQTT) protocol. To enable a JET application to subscribe to system log events, configure the extension-service statement at the [edit system extensions] hierarchy level. You can manage the JET application by using commands at the [edit system extensions] and [edit system services extension-service] hierarchy levels.
