Below given is one section of an event. The event has multiple such sections. I want to write a regex search query so that I can fetch the 3 fields from the below given log
1) 'Tableau Server (Service) ' (PD) is (Status).

I already wrote a regex query to extract it in the form of table for host and Status. But I am having problems in writing the regex query for 'Tableau Server (Service)' (PD) is (Status).

Extract - (Service), (PD) and (Status)

Thank you
Note: This is a sample modified log file

Following should work:

| rex max_match=0 "Tableau Server (?<Service>[^']+)'\s*\(?(?<PD>\d+)?\)?\s+(?:is|status\s+is)\s+(?<Status>[\w\s]+)\."

Only trouble with this: it gets the data into multi valued fields which means that you loose a reliable connection between the different parts of each line. So you might want to consider splitting this into individual events for each line, before extracting the individual fields.

It gives me the following error.
Error in 'rex' command: The regex 'max_matches=0' does not extract anything. It should specify at least one named group. Format: (?...).

Should I be adding something more to that query ?

try max_match=0 instead of max_matches=0
