I agree that Dynatrace Application Monitoring collects host health for different processes by default, but as per my understanding it collects overall CPU Usage not single process CPU usage.
I want to collect performance data(CPU Usage, IO Operations., Memory Usage, PID) for single process..
Why do you think that? We cover both host measures and process measures. It looks like you are in the right area for process measures. Have you charted host and process to compare? Have you looked at the Host Tile?
