Today I want to quickly share a query that shows Mbit used for a specific network adapter.

Perf
| where ObjectName == “Network Adapter”
| where Computer == “DC20.NA.contosohotels.com”
| where CounterPath contains “Bytes Received” or CounterPath contains “Bytes Sent”
| where InstanceName == “Microsoft Hyper-V Network Adapter”
| summarize avg(CounterValue) by bin(TimeGenerated, 5m)
| extend Mbit = avg_CounterValue / 125000
| project TimeGenerated , Mbit

This query can, for example, be used in migration scenarios to estimate network connection required. The query will convert bytes to Mbit.
