[stork-users] Monitoring kea with stork-agent

[Artem Pastukhov]

Hi all!
We are using Kea DHCP as a DHCP server for our virtual machines on several
subnets.
Now I'm trying to construct some alerts based on stork-agent kea metrics.
Two days ago we have an incident with address allocation failures:
```
Nov 22 12:04:30 ds-k8s-dhcp-1 kea-dhcp4[18672]: WARN
ALLOC_ENGINE_V4_ALLOC_FAIL [hwtype=1 00:50:56:9a:ea:c0],
cid=[ff:2d:1a:a1:33:00:02:00:00:ab:11:b0:15:9e:ac:fc:16:92:c1],
tid=0x6ca5c0a5: failed to allocate an IPv4 address after 221 attempt(s)
Nov 22 12:04:30 ds-k8s-dhcp-1 kea-dhcp4[18672]: WARN
ALLOC_ENGINE_V4_ALLOC_FAIL_CLASSES [hwtype=1 00:50:56:9a:ea:c0],
cid=[ff:2d:1a:a1:33:00:02:00:00:ab:11:b0:15:9e:ac:fc:16:92:c1],
tid=0x6ca5c0a5: Failed to allocate an IPv4 address for client with classes:
ALL, HA_ds-k8s-dhcp-1, UNKNOWN
```
But i can't figure which metrics are responsible to indicate such errors.

Can anyone give me advice?
