what is the correct way to force fields to be numeric?
As an example: message
timestamp=XXXX-XX-XXTXX:XX:XX red=0 yellow=44 green=60
If I just create an extractor that extracts key-value pairs, the resulting fields are not numeric. I tried making a custom index mapping, but that does not seem to help. Do I need to make an explicit extractor for all fields that has a “Numeric” converter in it?
If the field is first at some point a string, and then I make a numeric converter to make the future messages to have a numeric field, do I need to change the field name, or can the generate chart function skip the non-numeric values, and make the chart on the numeric ones?
