[prometheus, rails]如何在 rails 服务器上启用 prometheus

Question

我有一个实时 rails 应用程序，我正在尝试安装 prometheus monitoring service, using its Ruby Client。

我运行服务器上的教程运行良好，但一个小时后 merics url 死了。

如何让它在我的实时服务器上运行？

如果我添加现有项目，如下所示，Prometheus 会给出 "not found" 错误

我有两台服务器

promethus_server
live_server + 普罗米修斯客户端)

live_server 和 promethus_client 在不同的路径中。

我在服务器上手动运行 promethus 客户端:

$ rails new client
$ bundle (adding promethus-client Gem)
$ vi config.ru (add promethus lib)
$ rail s --binding=IP

这是正确的吗？

Answer 1

这是我最近升级的应用程序 config.ru 的样子：

require ::File.expand_path('../config/environment', FILE)
require 'rack'
require 'prometheus/client/rack/collector'
require 'prometheus/client/rack/exporter'

use Prometheus::Client::Rack::Collector
use Prometheus::Client::Rack::Exporter
