Interact metric with grafana and Ping service in K8S

Hi , I'm quite new to traefik , after I spend quite a lots of time , And I successfully config the dashboard through ingressRoute in K8S CRD ,now I able visit through external https ,
But Now I have another confuse ,How should I enable grafana to pulling the metrics , and link a heartbeat interaction with /Ping

Should I still configure an new ingressRoute for this ? I have an grafana running in the same cluster
