目前 agent 恢复了么?出现这个日志时候,可以进 agent pod,telnet 对应 server ip + port 看看连接情况

@1473371932 telnet是可以通的,猜测网络丢包的特殊情况导致该情况发生。一般出现这个,agent下一条日志就会显示连接成功,但是我看代码发现是不是会抛弃掉连接失败的那批buffer数据,不会进行重发。

一般来说,非网络断联造成的丢包都是可以通过 agent_group_config 配置来优化的,如果是由于网络断联导致的丢包,确实无法重发,因为 agent 本身并不存储数据

@1473371932 目前只是猜测是网络丢包的问题,想问下哪些配置可以优化该问题,我尝试下能不能解决

丢包问题,可以通过这个 Dashboard:
https://github.com/deepflowio/deepflow-dashboards/blob/main/dashboards/DeepFlow-System/DeepFlow-Alert-Analysis.json
看到具体丢包位置,把时间周期拉长,例如看最近 24 小时,如果面板中有数据,就说明有丢包,把有数据的面板贴一下看看
