logstash 启动是, 配置了修改配置自动重启, 

--config.reload.automatic

 

本来都好好的,  但是一次修改配置后, 某台机器上的logstash 开始不再上传日志了. 发现配置没有生效.

同时 logs/logstassh-plain.log  开始变大, 每隔几秒就打印一次上面的两条日志.

搜索了好久, 没有结果(看来大家logstash 都用的非常6了, 居然没有和我类似的错误).

(以下都是我结合官方文档自己想的, 不代表对)

大意是说

- 有过滤器太慢了, 阻塞了停止; 

- 如果强行停止,可能会丢失事件;

- 如果觉得丢几条没有关系, 可以在启动的时候使用 --pipeline.unsafe_shutdown

---

后来

我非常暴力的kill 掉进程, 重启了logstash .

一切正常了.

问题的原因并不知道, 但是主要耽误两天了, 我先把服务搞起来.

以后有缘再说.
