 - **Application gateway total time**
 
-  Average time that it takes for a request to be received, processed and its response to be sent. 
+   *Aggregation type:Avg/Max*
 
-  This is the interval from the time when Application Gateway receives the first byte of the HTTP request to the time when the last response byte has been sent to the client. This includes the processing time taken by Application Gateway, the *Backend last byte response time*, and the time taken by Application Gateway to send all the response.
+   This metric captures either the Average/Max time taken for a request to be received, processed and its response to be sent. 
 
-- **Client RTT**
+   This is the interval from the time when Application Gateway receives the first byte of the HTTP request to the time when the last response byte has been sent to the client. This includes the processing time taken by Application Gateway, the *Backend last byte response time*, and the time taken by Application Gateway to send all the response.
 
-  Average round trip time between clients and Application Gateway.
+- **Client RTT**
 
+   *Aggregation type:Avg/Max*
 
+   This metric captures the Average/Max round trip time between clients and Application Gateway.
 
 These metrics can be used to determine whether the observed slowdown is due to the client network, Application Gateway performance, the backend network and backend server TCP stack saturation, backend application performance, or large file size.
