DRDB description is confusing

[dmpop]

Hello,

DRDB's short description (https://github.com/ClusterLabs/ha_cluster_exporter/blob/main/doc/metrics.md#ha_cluster_drbd_connections=):

The DRBD subsystems collect devices stats by parsing its configuration the JSON output of drbdsetup

It doesn't make much sense. What does its refer to? And parsing its configuration the JSON output of drbdsetup has no logic.

I'd be grateful is someone could give an explanation.

Thank you!
