Regex Editor & Tester

Parses Nginx error log lines by capturing the timestamp (YYYY/MM/DD HH:MM:SS), severity level (e.g., error, warn, crit), process ID, thread ID, and message into named capture groups. Commonly used in log analysis pipelines and monitoring tools to extract structured fields from raw Nginx error logs. The global and multiline flags allow it to process every line across an entire log file.
