目前的系统进程情况 zabbix_agentd/mysql_alarm 监控

我说的负载是系统显示的负载, load average: 11.29, 11.64, 8.52
平时就是 mysqlcpu 占用比较高,在 100%-200%之间,系统负载升高的时候,mysqlcpu 占用也差不多没什么变化,
vmware 的虚拟机,宿主 cpu 占用也不高,
进程,ps -ef 查看,就是只有 prometheus export 和 zabbix 监控进程和 mysql,剩下的都是默认的系统进程
strace 查过 mysql 的进程.我不是很会看,如下,搜了下,貌似是正常情况,正常情况下也是这些东西一直 repeat.

感觉遥遥无期了,已经好几年了,实在需要集群的,就考虑别的队列吧,比如 kafka.
https://github.com/logstash-plugins/logstash-input-redis/issues/10

16-17 看上车时间的吧,
如果是翻倍前,应该乐开花了,
如果是翻倍后,应该也不会后悔吧,毕竟之后仍是一路走高,至少也是两位数的涨幅吧
反观 20 年,真是站在高高的山岗上,价格高点,利息高点

input 写多个 redis 呢?感觉也是可以满足的吧

@chackchackGO 试试不就知道啦.当执行了第二步后,所谓的反向链接,客户端的电脑上就可以执行服务器的命令了,搜下 shell 反弹,自行了解吧.
