Looks like I'm hitting this bug:
Here's the pertinent part of my config that uses trim:
# process key-value data is it exists
if [postfix_keyvalue_data] {
kv {
source => "postfix_keyvalue_data"
trim => "<>,"
prefix => "postfix_"
remove_field => [ "postfix_keyvalue_data" ]
}
I need to help to get around this so I can get back up and running. Looking at the docs for kv it looks like this needs to get updated to either trim_value or trim_key but I'm not sure which I should be using here?
Any help would be much appreciated.
