prometheus-mongodb-exporter - metrics per member in the set

[nivimorbgp]

Is your feature request related to a problem ?

I would like to see metrics per member in the set. For example, when querying for mongodb_connections, I get the number of current number connections for each member in the set, but there's no label on the metric to distinguish between the members. The resulting graph shows what seems to be spikes in open connections but it's actually the difference between open connections in the primary and secondaries. Seems like the exporter is pulling metrics round-robin.

Describe the solution you'd like.

Metrics should have a label indicating which member they belong to. This way it would be possible to monitor and detect issues in each member individually. Some metrics do have that label.

Describe alternatives you've considered.

When installing the mongodb-exporter directly on the member in the set, the metrics are labeled accordingly. But we prefer to install mongodb-exporter as helm chart in our K8S.
