What should you use?

You are troubleshooting a performance issue for an Azure Application Gateway.

You need to compare the total requests to the failed requests during the past six hours.

What should you use?
A . Metrics in Application Gateway
B . Diagnostics logs in Application Gateway
C . NSG flow logs in Azure Network Watcher
D . Connection monitor in Azure Network Watcher

Answer: A

Explanation:

Application Gateway currently has seven metrics to view performance counters.

Metrics are a feature for certain Azure resources where you can view performance counters in the portal.

For Application Gateway, the following metrics are available:

– Total Requests

– Failed Requests

– Current Connections

– Healthy Host Count

– Response Status

– Throughput

– Unhealthy Host count

You can filter on a per backend pool basis to show healthy/unhealthy hosts in a specific backend pool
