Exporter not initiating connection to mongo when Unauthorized

[dudigit]

Describe the bug
When Exporter works with mongodb + Authentication, when Unauthorizes, it dose not renew session to mongodb and keep error about authentcation

To Reproduce
Steps to reproduce the behavior:

1. Run mongodb with authentication
2. Run exporter with the following cmd line

/bin/mongodb_exporter --collector.diagnosticdata --collector.replicasetstatus
      --compatible-mode --mongodb.direct-connect --mongodb.global-conn-pool --web.listen-address
      \":9216\" --mongodb.uri \"mongodb://$MONGODB_ROOT_USER:$(echo $MONGODB_ROOT_PASSWORD
      | sed -r \"s/@/%40/g;s/:/%3A/g;s/#/%23/g;s/\\\\$/%24/g\")@localhost:27017/admin?

3. This issue happens sometime - not always - timing issue
   When exporter is running before the mongodb
   See many Unauthorized errors like:
   level=error msg="cannot decode getCmdLineOtpions: cannot execute getCmdLineOpts command: (Unauthorized) Command getCmdLineOpts requires authentication"

Expected behavior
When exporter is run with wrong credential is exited
I expect that the exporter will initiate it's session to mongo in case one of it's collector error with authentication
or at least exit

Logs
level=error msg="cannot decode getCmdLineOtpions: cannot execute getCmdLineOpts command: (Unauthorized) Command getCmdLineOpts requires authentication"

Environment

• OS - Limux
• environment - k8s
• MongoDB 7

Additional context
I would offer to add some logic at each collector something like

res := client.Database("admin").RunCommand(d.ctx, cmd)
var r primitive.M
if err := res.Decode(&r); err != nil {

    if e, ok := err.(mongo.CommandError); ok {

        if e.Code == Unauthorized { // Unauthorized = 13 

            logger.Errorf("unauthorized to run currtop: %s", err)

            os.Exit(1)
            // Can handle with reinitiate the connection as well 

        }

    }

}
