I feel like a Prometheus Gauge is not a great fit for this metric for consumption. It doesn't describe health/state of application as a whole but of current request. I do think that we want this data available but maybe a log would be better fit.
An idea for useful usage of gauges might be currently connected stake-weight percentage with subnets as labels.

JW how does this work with multiple subnets? Can we add a test case for that?

note how I constructed the metric name using the subnet ID here: https://github.com/ava-labs/awm-relayer/pull/434/files#diff-973f1f8ae5b8f6acd388e8c2fdaa6e08f999b4211536e8e3258b5df24de79d04R135
in short, the metric name/key for the existing test case comes out as connected_stake_weight_percentage{subnetID="11111111111111111111111111111111LpoYY"}.
If I understand correctly, we can't send a message from any subnets until the ACP-118 stuff is merged. (Right?) So at this time I can't add a test case for a different subnet, but I think the existing test does a good job of showing how it works.
