I frequently use Grok regexes, but combining complex log formats into a single pattern is still challenging. Especially when dealing with multiple date formats and variable-length message fields, I wonder which approach is more readable and maintainable when crafting patterns. What strategies do you prefer? Would you recommend building a reusable pattern library, using negative lookaheads, or defining custom patterns? I’d love to explore this together with examples. 🙏

In logs with mixed date-time formats, I feel it's better to abstract common parts with custom patterns for easier extensibility, but how effective are negative lookaheads in actual operations?
