Yes, you can probably combine traces and logs into a single category, and really what are traces but a collection of related logs with information about the relationship between them. But metrics are an entirely different beast. Sure some metrics can be derived from "events". But what about thinks like CPU and RAM usage? Do you want to record an event for every packet so you can measure network performance? And as mentioned above, you generally don't want to sample the things you have metrics if.
