I want to implement Sunbird Obsrv to collect telemetry data including user generated events. I have done setup of Kafka, zookeeper, postgres, redis and druid but unable to understand about implementation to collect telemetry data from an application using Sunbird Obsrv. Is this implementation require extensive code changes to our application or without code change we can start collecting telemetry data and how?
Can anybody provide help with this. I appreciate any assistance you can provide.
