[stork-users] DHCPv4 and V6 stats not displayed properly

[Buclin, Bertrand]

HI Stork team,

Looks like the Stork server GUI (version 1.10 and 1.11, at least; not checked on prior versions, agent version 1.10 and 1.11 too showing the same behavior; KEA 2.2) is not displaying properly the utilization of IPv4 subnets. The Kea Control Agent is showing its receiving and responding to the API call properly (log entries trimmed to relevant stuff only):


DEBUG [kea-ctrl-agent.http/594970.140579578214272] HTTP_CLIENT_REQUEST_RECEIVED_DETAILS detailed information about well-formed request

{"command":"stat-lease4-get","service":["dhcp4"]}

"rows": [ [ 200, 6, 5, 0, 0 ], [ 201, 15, 0, 0, 0 ] ], "timestamp": "2023-06-13 07:36:46.830289" } }, "result": 0, "text": "stat-lease4-get[all subnets]: 2 row

s found" } ]

But the Stork GUI shows:

It is showing the subnets (200 and 201), with the right number of total addresses, but it is not displaying the cumulative-assigned-addresses (should be 5 for the top subnet, and 83% utilization).

On Ipv6 subnets, I get something similar:


{"command":"stat-lease6-get","service":["dhcp6"]}

 0, 0, 0, 0, 0 ], [ 999901, 281474976710656, 0, 0, 0, 0, 0, 0 ] ], "timestamp": "2023-06-13 08:34:55.240818" } }, "result": 0, "text": "stat-lease6-get[all sub

nets]: 4 rows found" } ]



And Stork GUI shows :

It should show the 55 addresses assigned in the bottom subnet. It can show the 256 PD prefixes available in the top one, so clearly, it is receiving the API response and doing something with it.
