How Do You Configure Columnizer via Regex?

[MarkOD-AC]

I am looking to format a log into having the columns date, time, level, trace, and message. Each line has the following format:
[2025-11-25 09:03:04.409] [Info] [enso.rt.ga.server.SystemRpc] ...Successful
In this case, the value in the message column should be "...Successful".

Is there a simple way to get the log formatted by configuring one of the Regex columnizers?

Would prefer to avoid creating a custom columnizer unless creating and implementing one is very simple.

Got it to format into columns, but the columns aren't named.

Never mind, got it working with: (?[[]\S+)(?\s\S+)(?\s\S+)(?\s\S+)(?.*)

You should probably post the example wrapped in backticks. Otherwise the match group names (?<Name>\S+) are interpreted as XML/HTML tags in GitHub comments.

Here's an example for parsing Linux syslog lines with named groups:

(?<Date>\w{3}\s\d{2})\s+(?<Time>\d{2}:\d{2}:\d{2})\s+(?<Host>[^\s]+)\s+(?<Facility>[^:]+):\s+(?<Message>.+)

Not that it changes much but you don't need to match the spaces inside the groups. Here's what I'd use for your particular log format.

\[(?<TimeStamp>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d+)\]\s+\[(?<Level>\w+)\]\s+\[(?<Symbol>\S+)\]\s*(?<Message>.*)
