Build, test, and debug regular expressions
This PCRE2 regex extracts the text occurring between the literal strings 'id=' and '} Task is being killed'. It uses positive lookbehind and lookahead assertions to match the surrounding text without including it in the overall match. Note that while it defines a named capture group called 'taskid', this group is currently empty, meaning the actual extracted text will be captured by the unnamed group 1. It is highly useful for parsing application logs to identify task information right before a termination event.
