Question

在铁路应用中,装配包括

use Prometheus::Middleware::Collector

采集器代码如下:https://github.com/prometheus/client_ruby/blob/main/lib/prometheus/middleware/ therb 。

One of the most important principles in prometheus is to cause to have low cardinality metrics because otherwise performance crashes and it won t be useful to look at the graphs.

The essential part of the code which achieves it is at:

def generate_path(env)
        full_path = [env[ SCRIPT_NAME ], env[ PATH_INFO ]].join

        strip_ids_from_path(full_path)
      end

      def strip_ids_from_path(path)
        path
          .gsub(%r{/[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}(?=/|$)},  /:uuid\1 )
          .gsub(%r{/d+(?=/|$)},  /:id\1 )
      end
    end

因此,它与下级女佣合作,但不与上级女佣合作。

例如

uuid = "f7ec02c0-19b0-4519-8e3e-d8ac4434a389"
irb(main):024:0> strip_ids_from_path("user/#{uuid}")
=> "user/:uuid"
irb(main):025:0> strip_ids_from_path("user/#{uuid.upcase}")
=> "user/F7EC02C0-19B0-4519-8E3E-D8AC4434A389"

我只读中文本,修改法典。

strip_ids_from_path(full_path.downcase)

但是,采用整个法典并以这种方式加以规范是合情合理的。

是否有办法解决这一问题。能够利用铁路mag?

Answer 1

由于你已经找到了一种简单的解决办法,例如缩小了扼杀的范围。

您可以使用<条码>模块编号<>,以同样简单的方式执行。

module PrometheusMiddlewareExtension
  def strip_ids_from_path(path)
    super(path.downcase)
  end
end
Prometheus::Middleware.prepend(PrometheusMiddlewareExtension)
