The nxos-telemetry-to-kafka-go project is a standalone application that starts a gRPC server that implements Cisco's mdt_dialout.proto. It receives telemetry metrics from NX-OS devices and sends the results to Kafka, like a Minion would do it, so OpenNMS or Sentinel can consume them.

Part of that work can be ported to be used here as a Sink module.

Current implementation does not support SSL connections for Kafka.

I have a PR ready that implements this by utilizing the existing "brokerProperties" in a similar way as the gRPC broker does.

The OpenNMS XML Collector provides a more robust alternative compared to the HTTP Collector, giving us the ability to extract tabular data from XML or JSON via XPath or HTML via CSS Selectors.

That would be a beneficial addition to this project.

The original implementation requires using the gRPC server (either the external one or the one embedded within OpenNMS).

It would be wonderful for certain situations to use Kafka as the regular Minion does and offer an alternative to gRPC.

Of course, single-topic is still going to be required in OpenNMS for this to work.

The Graphite Integration is probably the easiest way to send streaming telemetry metrics to OpenNMS. For this reason, it would be useful to have this functionality here.

OpenNMS supports flow processing.

Minions can have a single listener per-flow implementation or an individual listener that supports multiple protocols simultaneously.

The listeners are not simple forwarders as the adapters would perform some work before forwarding to the Sink API.

Flows are one of the most significant features of OpenNMS and would be a massive improvement for this project.

To be able to monitor the gominion itself, it would be very useful to expose some useful metrics using Prometheus format.

Unlike SNMP, there are native libraries to work with Prometheus in Go (as that application was written in that language), so it would be useful to write it here.

Also, expose gominion metrics via Prometheus, as an alternative to what you get with JMX-Minion in Java.
