Good day,

I've been messing around with the flows in suricata2.1+ and I've come
across a potential requirement I would need it to do.

Currently it seems flows are only written out on connection close/timeout,
is this modifiable to include a update, or specific interval of traffic to
send a updated flow (ie, reason = update).

My issue is that I might have a flow last several hours on a stable
connection, and can only account for the traffic once the flow is closed.

I've had a look at the source code, however my C is very limited and I
can't work out what's actually writing out the flow records for the

Any help would be appreciated.
