Configuring Application Response Time (ART) on Cisco devices

ART metrics are extracted or calculated by the ART engine. These metrics are available only for TCP flows.

About this task

ART Flow fields configuration.

1. Configure to specify where the Flow data must be exported to:

   
   configure terminal
   flow exporter <NPI_exporter>
   destination 100.100.10.10
   source GigabitEthernet0/3
   transport udp 2050
   export-portocol netflow-v9
   option application table 	
   option application attributes 	
   exit
   

2. Configure a separate Flow record template for Application Response Time (ART) configuration as ART records contain bi-directional data:

   configure terminal
   flow record type performance-monitor ART_record
   match ipv4/ipv6 protocol
   match application name
   match connection client ipv4 address
   match connection server ipv4 address
   match connection server transport port
   collect ipv4/ipv6 dscp
   collect interface input
   collect interface output
   collect timestamp sys-uptime first
   collect timestamp sys-uptime last
   collect connection delay network to-server max
   collect connection delay network to-client max
   collect connection delay application max
   collect connection delay response client-to-server
   

3. Configure the Flow monitor that creates new NetFlow cache and the required Flow record and Flow Exporter:

   
   configure terminal
   flow monitor type performance-monitor ART-monitor
   exporter NPI_exporter
   record ART_record
   exit
   

4. Create the Performance Monitor Policy:

   
   configure terminal
   policy-map type performance monitor ART
   class class-default
   flow monitor ART-monitor
   

5. Associate the Performance Monitor to an interface:

   
   configure terminal
   interface <interface>
   service-policy type performance monitor output ART
