Missing Replica Set Metrics

[eroji]

Describe the bug
I currently have mongodb_exporter 0.40.0 installed with it connected against a replica set cluster. However, I don't see any metrics at all for replica set in the metrics endpoint. What am I missing?

To Reproduce
Steps to reproduce the behavior:

1. Install mongodb_exporter 0.40.0 with the following params for execution

MONGODB_URI=mongodb://127.0.0.1:27017/admin
MONGODB_USER=<user>
MONGODB_PASSWORD=<password>
OPTIONS="--collect-all --discovering-mode --compatible-mode"

3. Install MongoDB 7.0 and create the exporter user
4. Configure replica set
5. Navigate to /metrics endpoint for mongodb_exporter

Expected behavior
There should be metrics available for replica set

Logs
Please provide logs relevant to the issue

Environment

• OS: AlmaLinux 9.2

can you double check the exporter user has enough perms?
