@cestella The core of your idea that really solves the problem that I was
hung up on was adding two "result" expression; one for each destination.
* The HBase destination is just like it is now. I can write any
serializable Java Object.
* The Kafka destination is more limited. Its expression *must* result in a
String. We force the user to serialize the data. And we kind of have to, we
have no good way to embed a serialized object in a JSON message.
> Triage Metrics Produced by the Profiler

>
> h3. Problem
> The motivating example is that I would like to create an alert if the number
> of inbound flows to any host over a 15 minute interval is abnormal.
> The value being interrogated here, the number of inbound flows, is not a
> static value contained within any single telemetry message. This value is
> calculated across multiple messages by the Profiler. The current Threat
> Triage process cannot be used to interrogate values calculated by the
> Profiler.
> h3. Proposed Solution
> I am proposing that we treat the Profiler as a source of telemetry. The
> measurements captured by the Profiler would be enqueued into a Kafka topic.
> We would then treat those Profiler messages like any other telemetry. We
> would parse, enrich, triage, and index those messages.
> This would have the following advantages.
> 1. We would be able to reuse the same threat triage mechanism for values
> calculated by the Profiler.
> 2. We would be able to generate profiles from the profiled data - aka
> meta-profiles anyone?
