Information about Application Performance Monitor

The Application Performance Monitor feature is a simplified framework that enables you to configure intent-based performance monitors. With this feature, you can view real-time, end-to-end application performance filtered by client segments, network segments, and server segments. This information helps you optimize application performance.

An application performance monitor is a predefined configuration that is used to collect performance metrics for specific traffic.

Key Concepts in Application Performance Monitoring

  • Monitoring Profile: A profile is a predefined set of traffic monitors that can be enabled or disabled for a context. As part of this feature, the SD-Routing performance profile include Application Response Time (ART) aggregation monitor to monitor traffic passing through Cisco Catalyst SD-Routing interfaces. The SD-Routing performance profile has a dedicated policy to filter traffic based on your intent.

  • Context: A context represents a performance monitor policy map that is attached to an interface for ingress and egress traffic. A context contains information about a traffic monitor that has to be enabled. When a context is attached to an interface, two policy-maps are created, one each for ingress and egress traffic. Depending on the direction specified in the traffic monitor, the policy maps are attached in that direction and the traffic is monitored.

Application Performance Monitor Workflow

You can enable performance monitor only on Direct Internet Access (DIA) interfaces. Performance is monitored for traffic going out of, and coming into the DIA interfaces. You can then view details of the application that you are monitoring using various show commands.

Prerequisites for Application Performance Monitoring

  • Minimum software version for Cisco IOS XE Catalyst SD-Routing devices: Cisco IOS XE Catalyst SD-WAN Release 17.13.1a

Limitations

The limitations for Application Performance Monitor are:

  • The Application Performance Monitor support only ART on the SD-Routing device.

  • Only Direct Internet Access (DIA) scenario is supported in this release

  • Performance monitoring is only supported on IPv4 traffic. IPv6 traffic is not supported.

  • Application Performance Monitor does not support multi application-aggregation monitors on the device.

  • The class-map used in APM only supports maximum two layer class-map and does not support three or more layer class-map.

  • Only CLI based config group is supported on Cisco SD-WAN Manager to config APM for SD-Routing device.

Configuring Application Performance Monitor

You can enable application performance monitor on DIA interfaces and monitor the traffic metrics for ART.

Enabling Performance on DIA Interface

The following example shows how to configure a performance monitor context using the SD-Routing application-aggregation profile. This configuration enables monitoring of traffic metrics for ART and applies it to a specific interface.

Configuring Application Performance Monitoring on SD-Routing Device

To create a configuration group, perform these steps:

Procedure

Step 1

From Cisco IOS XE Catalyst SD-WAN Manager menu, choose Configuration > Configuration Groups > Add CLI based Configuration Group .

Step 2

In the Add CLI based Configuration Group pop-up dialog box, enter the configuration group name.

Step 3

Click the Solution Type drop-down list and select the solution type as sd-routing for the SD-Routing devices.

Step 4

In the Description field, enter a description for the feature

Step 5

Click Next.

Step 6

Click the Load Running Config from Reachable Device drop-down list and select the running configuration or add the configuration CLI in text box.

Step 7

Click Save

Step 8

Click … adjacent to the configuration group name and choose Edit

Step 9

Click Associated Devices.

Step 10

Choose one or more devices, and then click Deploy

Note

 

Application Performance Monitoring does not support performance monitor context profile and flow monitor change when the performance monitor context profile and flow monitor are attached to an interface.

Step 11

Click Configuration > Configuration Groups > Deploy

Step 12

Click … adjacent to the configuration group name and choose Edit to modify performance monitor context profile and flow monitor and re-attach it to the interface.

Step 13

Click Deploy.

Step 14

Click Save.

Verifying Application Performance Monitor

To verify the Application Performance Monitor configuration on the SD-Routing device , use the show performance monitor cache monitor command.
