Logstash 主要是用来日志的搜集、分析、过滤日志的工具,支持大量的数据获取方式。一般工作方式为c/s架构,client端安装在需要收集日志的主机上,server端负责将收到的各节点日志进行过滤、修改等操作在一并发往elasticsearch上去。 优点 可伸缩性 节拍应该在一组Logstash节点之间进行负载平衡。

ES client 默认会针对查询报错的长连接,会将其加入黑名单(blacklist),client 流量会发生倾斜。当客户端发生流量倾斜后,ES 默认会对发送到该可用区的查询,会优先查该可用区的副本,旨在减少搜索延迟,但这个机制在高并发场景下也可能会导致可用区查询流量不均。可以通过参数(es.search.ignore_awareness_attributes)设置...
