Splunk Search

Help extracting fields from raw event

Here's what my raw event looks like:

58daf92d66c83d000e469dfd.txt unsupported file format 

I'd like to extract the following below during a search, to pull these fields:

  • task = 58daf92d66c83d000e469dfd
  • fileExt = .txt
  • errorReason = unsupported file format

How can I accomplish this using Rex?

Maybe something like:

| rex "(?P<task>^[^\.]+)(?P<fileExt>\S+\s(?P<errorReason>.*)"

I'm unsure if that first part should be [^.] or [^.]

The built in regular expression creator could help here or sites like https://regex101.com/
