It's fine to collect this information in your logs as it's part of the normal operation. I log them for security reasons and the logs do not persist for more than a week or two, which is less than the month I'd have to comply within. Provided you're not logging IP addresses for non-legitimate reasons and you're not keeping the data for longer than you reasonably need to, you have nothing to worry about.
