We need QOS built-in Garfana Dashboard

I need to setup QOS built-in Garfana Dashboard and for that, I need till now I have gone through the topics like, how Grafana works with Telegraf (Data collector) & InfulxDB and how InfluxDB connects to Grafana so that Grafana can query it to create wonderful dashboards, Visualizations, Graphs based on metrics inserted to infulxDB by an application called Telegraf.
I have also worked with Cisco TAC in order to determine or confirm the required/correct object, OID & MIB information for polling.
Cisco Class-Based QoS MIB

Policy-Map OID

But from here I have no idea how I should proceed further to fulfill my requirement.
Can someone please assist me with what next step I should follow from here ?
