[Kea-users] Logging Option 82 Circuit-id and Remote-id.

[Tim Nowaczyk]

Hello,

I have a requirement where Ineed to log the details from the DHCP Option-82 field whenever a lease is allocated so that we can go back and see which customer was using a particular IP at a given time. The current output of the DHCP4_LEASE_ALLOC message just contains a mapping between MAC address and IP address. Is there a different logging logger name we should be logging that would contain these details? Does anyone have any suggestions on how we can accomplish this?

2025-11-19 15:44:13.438 INFO  [kea-dhcp4.leases/160072.131853078283968] DHCP4_LEASE_ALLOC [hwtype=1 00:11:22:33:44:55], cid=[no info], tid=0xdb58de5a: lease 198.51.100.2 has been allocated for 300 seconds

We are running Kea 3.0.2

Thanks,
Tim Nowaczyk
