Packet sizes, times, source and destination IPs.

Logs of the above data - aren't ISPs required to record it for all
users, and keep it for 6 months/two years/whatever?

I thought they were anyway, isn't it some EU law?

In any case, if the ISP didn't keep logs of the above data, the person 
demanding the data could require them to collect and keep it, see RIPA

No, there is no content involved, and therefore no interception.

It comes under s.22(4) of Chapter 2 of Part 1 of RIPA, "Acquisition and 
disclosure of communications data", and lots of people can demand the data.

Offhand I can't remember exactly who is on the list, it's in one of the 
SIs somewhere, but for the Police it's something like a Chief Inspector, 
and various equivalents in other forces/agencies.

They keep changing it, but it's the same list of people that at one time 
(in)famously included the egg marketing board inspectors.
