单机创建客户端上限

Negan · 2023 年2 月 22 日 01:33

本机环境用的最新版本5.0.17，win10，i7-10750H，16G内存，java8

用的50个线程创建客户端，本地创建到16500左右，server端就崩溃无法连接了
我这瓶颈是在哪块？

我要在win10环境下如何做单机的压力测试，不能换平台的情况下（要用winServer）。

你好，可以看下 log 目录下有没有生成 crash.dump 文件，有的话可以把前两百行的内容贴一下，我们可以看一下崩溃的原因。

看起来确实有很多报文日志，但基本都是比较普通的问题，比如消息队列满了，然后开始丢弃消息了；你配置的 Prometheus 服务无法连接等等。

但这些都不会导致 EMQX 崩溃。方便把完整的 emqx.log.* 发一下吗？

Negan · 2023 年2 月 22 日 02:00

服务器上用的老版本，所以我本地新旧2个版本都测了的，我把两份日志都给你吧

emqx log.zip (1.6 MB)

Negan · 2023 年2 月 22 日 07:58

有什么发现吗？是跟我本地哪块用法有关系吗？

t1ger · 2023 年2 月 22 日 08:17

你给的日志是 EMQX 发生崩溃的机器上的日志吗？

Negan · 2023 年2 月 22 日 08:59

对的

t1ger · 2023 年2 月 23 日 02:22

日志里面没有更多的信息，怀疑是占用内存过多被操作系统 Kill 了，你可以看下操作系统的系统日志。

Negan · 2023 年2 月 23 日 06:26

我观察了很多次控制台，EMQX后台内存占用管理的很好，一般都在500兆左右，但CPU占用倒是会随着客户端连接数量增大而增大。

是看这里的日志还是看哪块位置的？

我本地用4.2.0在8174左右客户端数量后崩溃，用5.0.17在16324左右客户端数量后崩溃，这最新版本是在哪块做了显著优化吗？我们也想知道，windows环境下使用EMQX的瓶颈到底是在哪里？我们也可以自行尝试优化这块或者规避瓶颈问题。

t1ger · 2023 年2 月 23 日 07:37

是不是文件描述符占用达到最大限制了？

这个我就有点听不懂了，你可以告诉我改哪里的配置，我本地可以反复测试观察的比较方便。

如果有什么分析结果的进展及时回复我，我们还准备先在win10上优化看看效果的，然后再去winServer上试试。

你好，还是建议在 Linux 环境中部署 EMQX。

那我用emqtt-bench测试单机的话，上限就只能是65000？

再补充一个现象，在win10下连接最近版，连接到16300左右 win10的机器会断网服务端状态正常，只有把本地的多线程创建客户端的程序关闭了win10的机器才能上网。

可以通过增加网卡虚拟ip 和更多的监听端口来超过 65000 的限制

我单机docker启动最多28230，不知道为啥这么稳定，系统连接数没问题，测试别的应用可以到60000

windows启动没问题，可能是docker容器限制的问题
