The following table lists the metrics available for the Microsoft.Network/applicationgateways resource type.

Table headings

Metric - The metric display name as it appears in the Azure portal.
Name in Rest API - Metric name as referred to in the REST API.
Unit - Unit of measure.
Aggregation - The default aggregation type. Valid values: Average, Minimum, Maximum, Total, Count.
Dimensions - Dimensions available for the metric.
Time Grains - Intervals at which the metric is sampled. For example, PT1M indicates that the metric is sampled every minute, PT30M every 30 minutes, PT1H every hour, and so on.
DS Export- Whether the metric is exportable to Azure Monitor Logs via Diagnostic Settings. For information on exporting metrics, see Create diagnostic settings in Azure Monitor.

Metric	Name in REST API	Unit	Aggregation	Dimensions	Time Grains	DS Export
Application Gateway Total Time Time that it takes for a request to be processed and its response to be sent. This is the interval from the time when Application Gateway receives the first byte of an HTTP request to the time when the response send operation finishes. It's important to note that this usually includes the Application Gateway processing time, time that the request and response packets are traveling over the network and the time the backend server took to respond.
