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?

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, 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.
