The values OP is seeking is in the field message. (From the illustration in OP, the event is JSON - but it is best to illustrate with raw text, not a copy from Splunk's formatted event view.)  So

| rex field=message "Received update request (?<IL_Customer>[^\.]+)\. Size of array: (?<ArraySize>\d+)"

(Also slightly more efficient because the regex engine would be scanning smaller strings.)

There's probably a JSON-ic way to do that (assuming the event is pure JSON), but rex can handle a few fields nicely.

Assuming the order of fields is fixed, this regex should do it.

 

| rex "Received update request (?<IL_Customer>[^\.]+)\. Size of array: (?<ArraySize>\d+)"
