I have certain fields where the value is a numeric and it represents a certain status (e.g. 0 - OK, 1 - User Error, 2 - System Error etc). But if I show just the numeric value in a report, it's not really intuitive to interpret. I know that it's not possible to aggregate parent-children in Kibana right now, but is there a way that I can do a decorator so that I can manually map the values to show "OK" when the value is 0 ad so on? That would at least make it friendlier for a layman to view the dashboard.
