I'm trying to rex out a chunk of events, then remove that field from the events prior to piping to the cluster command.
So something similar to:
blah | rex "resolving '(?<some_fqdn>[\w\d\.]+)' " | fields - some_fqdn | cluster
So that the chunk extracted in the some_fqdn field doesn't contribute to making the event seem more unique.
I know that cluster by default analyzes the _raw field and am assuming that the 'fields - some_fqdn' is not removing from the _raw field.
So I guess my question is how do you remove a field from _raw prior to sending to another piped command, or how do you create a new field that is the equivalent of _raw minus some_fqdn (to then tell cluster to work off that new field)?
