'Azure Monitor metrics based on sum of existing metric values
I have a network resource that only has bytes in and bytes out as metrics, I want to derive another metric with the addition of both bytesin+bytesout. Please suggest how I can add both in & out values and create an Azure Monitor Alert rule based on this new metric.

You cannot create a new metric by combining to existing ones. However, you can create an Alert Rule on a custom query. That means we can create a query like this
AzureMetrics
| where MetricName == "BitsInPerSecondTraffic" or MetricName == "BitsoutPerSecondTraffic"
| where ResourceType == "EXPRESSROUTECIRCUITS"
| summarize AggregatedValue = sum(Total) by bin(TimeGenerated, 15m)
Use that query to create an alert using the azure portal:
