Grafana dashboard: Network Device Dashboard 
Description: Created a network dashboard to monitor device status + Interfaces.  Hopefully, it helps the community. 

Current Dashboard shows, 

Power Supply,
Availability, 
System Uptime, 
Temperature,
CPU Utilization, 
Memory Utilization, 
ICMP Response time, 
Specific Interface Incoming / Outgoing Traffic (Bits + Error) 
All Interface Incoming / Outgoing Traffic (Bits + Error) 

Global variable to select, $Group (In this case, Network), $Host, $Interface (All or Specific). 

Hope it helps.
