I configured process plugin to keep track of hundreds of processes, but I am only interested in specific metrics(CPU, Memory).
The result is I now have a lot more data being collected than I actually need, potentially increasing storage requirements and in some cases storing useless information like:

Singular processes that only ever spawn a single process don't need to have a number of process metric saved.
Stack size for applications that have a fixed stack size.
Virtual memory that is always = all system memory.

It would greatly help if the specific metrics stored by the plugin could each be turned off. There are already some config parameters to turn things off, but they do not cover all the potential data points.
