By following the Dynatrace documents, we could Set up AKS monitoring via Dynatrace Operator using the manual mode "classicFullStack Installation". we could add the kubernetes workloads to the dynatrace and able to monitor the infrastructure component like nodes cpu and memory resources and running workloads etc.
But actually we were looking to get the application traces like service flow diagram of apps which are running kubernetes, like what backend service callings, services response time, traffic flow etc, and etc..
But after installing the operator in AKS and oneagents deployments to the aks nodes, we are able to get process and workload information , but we are not able to get these services traces in dynatrace.
