The Flow API is now composed of the following methods:
- Flow::setDetectedProtocol to manually set a protocol on the flow
and terminate the dissection
- Flow::processPacket to run the nDPI dissection on the raw packets
- Flow::endProtocolDissection to terminate or give up the dissection
Also fixes the flow sampling rate preference, which was never used.
- Move score from status definition to user scripts
- Separate flow score counter from the peers score
- Create a new HostScore class to hold the score data
The score is now calculated differently on the client and on the server of the flow.
The hosts flow is updated every minute and charted.
It's now possible to trigger an alert when the score threshold is exceeded
