The workflow for ingesting custom telemetry into Crosswork Assurance has been simplified in recent releases.
Telemetry ingestion is a paid customization service provided by Cisco CX and Partners.
Pre-requisite:
A Telegraf configuration file that collects the desired metrics from the data source must be available. This configuration is provided by Cisco CX and Partners.
Workflow:
Follow the instructions for configuring a Telemetry Collector, choose the "custom" option, and use the file upload feature to upload a Telegraf.conf configuration file.
This creates a custom Telemetry Collector that is specific to the use case/configuration designed by CX/Partner.

Follow the instructions to deploy the Telemetry Collector and Sensor Collector (in either Docker or Kubernetes) to get the data flowing into Crosswork Assurance.
Leverage the ingestion staging feature to curate and edit the incoming data to meet the customer's specific needs/preferences.
These features are all leveraged by Cisco CX and Partners to design and implement custom telemetry ingestion from various data sources in the customer network.
