Description

Router' RBFMetrics was not register  in MetricsSystem. We can't find these metrics from PrometheusSink. Maybe we should fix it. 

 

After fix it ,  some  RBFMetrics will export like this 

# HELP rbf_metrics_current_tokens_count Number of router's current tokens
# TYPE rbf_metrics_current_tokens_count gauge
rbf_metrics_current_tokens_count{processname="Router",context="dfs",hostname="xxxx"} 2
