Implement centralized log collection, parsing, and querying with Loki/Promtail or ELK stack for operational visibility.

Select between Loki (Prometheus-style) or ELK (Elasticsearch-based) based on requirements.

For this guide, we'll focus on Loki + Promtail (recommended for most modern setups).

使用 Loki 和 Promtail（或 ELK 堆栈）设置集中式日志聚合，包括日志解析、标签提取、保留策略以及与关联指标的集成。当将来自多个服务的日志合并到可搜索系统、用集中式可查询存储替换本地日志文件、将日志与指标和跟踪相关联、通过标签提取实现结构化日志记录或对需要跨服务日志分析的生产事件进行故障排除时使用。 来源：pjt222/development-guides。
