I have problem with saving regex for extracting class name
Here is my regex
And here is log sample
12.02.2015 12:14:16.946 INFO [10.36.27.187  GET /content/company/global/en/company/notices/polish.html HTTP/1.1] com.company.web.core.cdn.CDNTransformer CDN: http://static-dc.company.net

And here is splunk error
"Invalid regex: no named extraction at position 5 (i.e., "[([0-9a-zA..."). Expected "(?P<variable>pattern)""
You'll need to fix the formatting on your regex so it displays properly in the browser; we can't read it as is. Edit your question and substitute & # 92; (with no spaces) for all the backslashes.
The forward slash needs to be escaped.
You have nested capturing groups. Is that intentional?
This regex string works with your example log entries on regex101.com. It also handles nested brackets.
