如何利用Filebeat高效实现Linux系统日志的实时监控与运维效率提升？

fileBeat setup --modules # 自动加载 Ingest Pipeline & Dashboard & Index Template # ⚠️ 模块会自动注册 Ingest Pipeline 做结构化解析，省去 Logstash 开发成本！请务必执行 setup！️️️️️️️️️️️️️️縧ÙÇÇÇÇÇÇÇÇÇ''''>

🔧 参数解读：
'worker auto': 自动匹配 CPU core 数并发写入；'bulkmaxsize auto': 批次大小，吞吐与延迟平衡；'queue.mem.events': 默认 MB 内存队列，突发流量吸收池；若磁盘允许可改 queue.disk 落地持久化，宕机不丢单；'retry async + exponentialbackoff': ES 集群抖动时指数退避重试，保护上游不雪崩；老实说，'compression_level gzip': 带宽省 ~%。CPU 损耗微乎其微，不过，>>>
