Application Response Time Report Group

The Application Response Time reports show Cisco's Application Response Time (ART) metrics. ART metrics are available for IPFIX flows from routers that have Cisco ART metrics enabled.

Meaningful data is shown in the Application Response Time reports under the following conditions:

The routers and interfaces in the report are configured to export IPFIX flow.
The exported flow includes the appropriate fields.
If a router is not configured to return data for the appropriate fields, a zero (0) appears in the corresponding table cells. Non-NBAR2 traffic shows a zero for all of the values except the router IP address and application name.

The Application column values show the NBAR2 application name followed by the application ID. The application name is included if it is defined by the standard (not custom) NBAR2 engine. Otherwise the Application value may consist of only the application ID.

The Application Response Time group of Flow Forensics reports show the following fields.

Report	Router Addr	Application	Transactions	Avg Total Transaction Time	Late Responses	Retransmissions	Client Address	Server Address	New Connections	Avg Client Network Delay	Avg Server Network Delay	Avg Response Time	Avg Application Delay
Application Metrics	Y	Y	Y	Y	Y	Y
Client Side Metrics	Y	Y					Y	Y	Y	Y
Server Side Metrics	Y	Y							Y		Y	Y	Y

Application Metrics Report

Displays a summary of ART metrics for IPFIX flow that includes NBAR2 data. The report table includes a row for each unique combination of the following values:

IP address of the router that sent the data
NBAR2 application name
Number of transactions
Number of late responses
Number of times that lost packets were retransmitted
Average of the total transaction time, which is calculated from the flow record data

Client Side Metrics Report

Displays client-side ART metrics for IPFIX flow that includes NBAR2 data. Each row shows the values for a unique combination of the following values:

IP address of the router that sent the data
NBAR2 application name
IP addresses of the client and server
Number of new connections
Average client network delay

Server Side Metrics Report

Displays server-side ART metrics for IPFIX flow that includes NBAR2 data. Each row shows the values for a unique combination of the following values:

IP address of the router that sent the data
NBAR2 application name
Number of new connections
Average server network delay
Average response time (includes the network time from the client to the server and the server response time)
Average application delay
