Hi Jim,

This should be very easy to configure as the default mode of the forensic
logging hook is to log option 82 data if present. The hook is documented
here:
https://kea.readthedocs.io/en/kea-2.6.1/arm/hooks.html#libdhcp-legal-log-so-forensic-logging<https://kea.readthedocs.io/en/kea-2.6.1/arm/hooks.html#libdhcp-legal-log-so-forensic-logging>

A very simple configuration which should do what you describe is the first
example in the documentation. You may need to play with log rotation and
retention settings to keep what you want for as long as is required.

Thank you,
Darren Ankney

Hi Uwe,

Have you loaded the stat_cmds hook in Kea? Stork needs this for at
least some of the statistics. See here:
https://kea.readthedocs.io/en/kea-2.6.1/arm/hooks.html#libdhcp-stat-cmds-so-statistics-commands-for-supplemental-lease-statistics<https://kea.readthedocs.io/en/kea-2.6.1/arm/hooks.html#libdhcp-stat-cmds-so-statistics-commands-for-supplemental-lease-statistics>
