Bug Description

I have MAAS providing DHCP and monitoring the network. When I look at the interface, I see a number of observed nodes, but I can't see which of those have been given addresses by the MAAS DHCP server and which are genuinely rogue.

Ideally:

 * the subnet listing would show leases currently outstanding on that subnet
 * the vlan reserved range would show number / percentage used and link to a list
 * the discovery dashboard would flag items that got their IP from MAAS DHCP

Good ideas. We'll see what we can do for MAAS 2.4.

In the case of MAAS-managed DHCP, we can join the discovery view with the StaticIPAddress table and check for an allocation type of DHCP to determine whether or not a MAAS DHCP server handed out the lease.

I wonder if it would also be appropriate to highlight addresses that did NOT come from MAAS DHCP, and do NOT have an entry in the StaticIPAddress table. That would indicate a "likely rogue" address (if the subnet is a managed subnet).

Changed in maas:
status: New → Triaged
importance: Undecided → Medium
milestone: none → 2.4.x

Yes, I think that would be very helpful. Addresses that are on the network but not recorded in MAAS are 'rogue' even if they don't conflict with anything else, because we want MAAS to be a full and accurate record of every device on the LAN.
