Cisco Catalyst Centre Telemetry

hello

I am working on an installation of Cisco SDA

I am trying to collect information on packet loss from the management interface

under Assurance >Health>Client I can see a section on Application with packet loss as a heading

there are no entries in the table and therefore no information on packet loss experienced by the client

Q are there other ways to view packet loss ?

there are also pre-set values for Voice & Multimedia for example

the client I checked had a health score of 10 -- does this mean the packet loss experienced was less than 0.05% ?

what version of DNAC (Cat C) here, what Switch model and IOS XE Code ?

this all depends on the configuration applied.

Individual Application Health Score

The Individual Application Health score is calculated based on the weighted average of the application's qualitative metrics, which include packet loss, network latency, and jitter.

The Individual Application health is measured on a scale of 1 to 10, with 10 being the best score. The following formula is used to calculate the Individual Application Health score:

Individual Application Health Score = (Latency_Weight * Latency_VoS_Score + Jitter_Weight * Jitter_VoS_Score + PacketLoss_Weight * PacketLoss_VoS_Score) ÷ (Latency_Weight + Jitter_Weight + PacketLoss_Weight)

Note	The health score is not available for Cisco Catalyst 9000 Series Switches and Cisco AireOS wireless controller. These devices do `not` poll the KPIs that are required to calculate a health score.

The workflow for calculating the Individual Application Health score is as follows:

Obtain the KPIs: Jitter, Latency, and Packet Loss.
Determine the application's Traffic Class based on the DSCP value from the flow record.
Convert the KPI numbers into Validation of Service score (VoS score) using the Cisco Validated Design (CVD) thresholds for each Traffic Class and KPI metric.
Get the weightage of the KPIs based on the application's Traffic Class and Tolerance level. The weightage is based on RFC4594.
Calculate the Application Health score. This is the weighted average of packet loss, network latency, and jitter.
