Hi,
If you mean remove in ES, use this -
trim_value => """
For example -
kv {
source => "kvmessage"
trim_value => "\""
remove_field => [ "kvmessage" ]
remove_field => [ "message" ]
}

This is great but does anyone know how to remove the double quotes out of the output? I'm trying with grok's mutate options but not having much luck
