I have a log stream that includes a reference.keyword and several accumulated values.
What I need to understand is the rate of change. So I need to understand the difference in the values from the previous log with the same reference.keyword.
I know I can plot this using the Serial_Diff or Derivative options, however, what I cannot do is look at the top 10 rates of change, as the plot functions will all do that based on the accumulated values (which don't correlate well with rates of change.
So, the question, is there a method to add fields to the log that takes the prior log (with the same reference.keyword) into account?
Alternatively, is a watcher an option - whereby the watcher is able to add the rate fields where they don't exist?
