大家好，我们正在尝试解决我们的 Discourse 安装在过去几天中出现的问题。
我们使用的是 Contabo 云 vps，8 核/32GB/nvme，用户量约为 150 人；在过去的两年半里，我们很少遇到问题。
从上周末开始，由于 CPU 使用率异常高，实例出现了几乎无法使用的时刻。
为了排查这种情况，我们昨天将论坛设置为只读模式。我有一些 Grafana 图表显示了我们的情况——三个标记指示了我们开启只读模式的时间、我们重启容器的时间以及我们关闭只读模式的时间。
（更多图表请见：Imgur: The magic of the Internet
正如你们所见，使用率非常高。这种情况始于几天前，因此存在某种我们尚未妥善排查的问题。
在开新帖之前咨询了 AI 助手后，我可以补充说 Sidekiq 存在一些异常进程：
Jobs::ProcessBadgeBacklog 大约需要 2-5 秒
上一个 DestroyOldDeletionStubs 花费了 475 秒。
上一个 DirectoryRefreshDaily 花费了 580 秒。
上一个 TopRefreshToday 花费了 18 秒。
那么，问题是——以我们使用的用户群和硬件来看，什么可能导致这种情况？
谢谢！

I think somehow you’re short of RAM. You have 32G. But possibly you have some process or processes using more than expected.
Perhaps capture ps aux in a window about 120 chars wide. Here’s mine:

我注意到在繁忙时段有大量的系统内核时间，这通常意味着分页。您可以随时运行vmstat 5 5

This is definitely a memory issue: I’m seeing some huge queries here.
The question, now, becomes “what is causing these queries to be so big”, because it happened suddenly and I assume our case (150 users, 1000 posts per day) should not be having issues with this amount of memory.

char:
这绝对是内存问题：我在这里看到了一些巨大的查询。
您最近重启过吗？
看起来有一堆空闲的 postgres 进程占用了大量内存，我想是这样。
在您的 app.yml 中您为 postgres 分配了多少内存？您更改了默认设置吗？
另外，Postgres 13 已经有一年没有得到支持了。您真的需要升级了。我原以为 Discourse 不支持 PG13——您运行的是哪个版本的 Discourse？

这在我看来不像是一个内存问题——应用程序只占用了大约 6GB。有很多读取 操作正在发生，我猜测（以及 sidekiq 很忙）这可能是 postgres 正在从磁盘读取大量旧数据，可能是为了执行一些统计作业。如果数据库无法完全装入 RAM，那么在访问旧数据时，它可能会进行大量的读取操作。这闻起来像是这种情况。

我建议首先查看 sidekiq——我敢打赌它正在忙于运行更新。以管理员身份登录后，查看 /sidekiq URL，看看它在做什么。这很可能会显示一些长时间运行的更新任务。
你也可以在 SQL 服务器上执行：
SELECT pid, application_name, query
FROM pg_stat_activity
WHERE state IS NOT NULL
AND state != 'idle';
以查看正在运行的查询以及调用它们的程序。这将提示导致负载的原因是什么。
你是否启用了性能标头 ？你可以在日志中打开它们并捕获它们，以告诉你 Discourse 在每个部分花费了多少时间。

内核的 swapd 已经占用了相当多的时间。很可能分页活动没有被短暂的 vmstat 运行捕获到。
看起来有很多 postgres 进程占用了或多或少的 20% 的内存。考虑到可用内存，进程是否太多了？？检查 postgresql 配置是明智的。
但在继续重新测量之前，重启也是明智的。
由于内存百分比加起来远远超过了，一定存在一些不可见的共享。不过，这看起来确实有很多大型进程。

一定有一些不可见的共享
Discourse 在初始化后会进行分叉，以尽可能多地利用共享，是的。

情况已经有所改善。
我们不确定具体是哪个操作解决了问题，但我们现在运行良好。
目前情况似乎稳定了。
感谢您迄今为止的帮助。
