DNA Center 2.1.2.5 Assurance Application Experience

[mkoschay123]

Hello,

does somebody know what's missing after Telemetry activation to see the Appliaction metrics. eg. RTP ?

I just see the bandwidth consumed for RTP but no metrics e.g. DSCP values were processed from Netfow data.

Best regrads,

Michael

Out of curiosity, is Application Experience deployed on router, switches, or both in your deployment?

Hi @mkoschay123 

What devices have you enabled for Telemetry? For info, the Cisco Catalyst 9000 switches support Application Visibility (collection of application name and usage metrics - referred to as Quantitative metrics) and Cisco IOS-XE based Integrated Services Routers support Application Experience (collection of application name, usage, packet loss, latency and  jitter metrics - referred to as Qualitative metrics). 

Based on your screenshot, I'm assuming that you have enabled Telemetry/Netflow on Catalyst 9k switches only? If so, DNAC will only collect Quantitative metrics and report application name and usage only. If you need Application Experience/Qualitative metrics, then you will either need to enable telemetry on a router (if one exists in your deployment, and if the RTP traffic actually transits this router) or deploy a Cisco DNA Traffic Telemetry Appliance. 

See the following for further details

Hope that this helps

Thanks Will,

indeed this ia a C9300L. I was assuming that DNA-C makes no difference, as the netflow data contains the IP dscp values.

That points to the question, is a C9500-48Y4C acting as border device a qualified router or still just a switch.

Thanks,

Make sure performance monitor is activated on the network devices.

Network monitor, is the service giving you the session information about packet loss and delays.

Hey Rasmus,

I will try that. But I really thought that DANC would be activating anything needed to gather all AppExp metrics.

Thanks,

Michael
