Question

我使用Memcached作为Radiant缓存资源设置了Radiant实例，但是，似乎没有将缓存命中记录到Radiant。

以下是缓存实现的示例：

# file: :rails_root/config/environments/[RAILS_ENV].rb
require 'dalli'
$cache = Dalli::Client.new(["remotehost.com:11211", "127.0.0.1:11211"], :compress => true)
config.middleware.use ::Radiant::Cache, :metastore => $cache, :entitystore => $cache

当我在Radiant实例上加载（通过httperf）时，只有缓存未命中在NewRelic中注册。

有些事情值得注意：

我正在使用nginx和独角兽。

我目前要求:rails_root/config.ru中的newrelic如此：

begin
  require 'newrelic_rpm'
  NewRelic::Agent.after_fork(:force_reconnect => true)
rescue LoadError
  # proceed without NewRelic
end

我正在使用bundler，这是我的Gemfile示例：

source "http://my_gem_server"
source :rubygems

gem "radiant", "~> 1.1.0"
gem 'unicorn'
gem 'therubyracer', '~> 0.9'
gem 'newrelic_rpm'
gem 'rack-cache'
gem 'dalli'
gem "compass-rails", "~> 1.0.3"
group :extensions do
  # radiant extensions
  gem "radiant-archive-extension",             "~> 1.0.7"
  gem "radiant-clipped-extension",             "~> 1.1.0"
  gem "radiant-debug-extension",               "~> 1.0.2"
  gem "radiant-exporter-extension",            "~> 1.1.0"
  gem "radiant-markdown_filter-extension",     "~> 1.0.2"
  gem "radiant-snippets-extension",            "~> 1.1.0"
  gem "radiant-site_templates-extension",      "~> 1.0.4"
  gem "radiant-smarty_pants_filter-extension", "~> 1.0.2"
  gem "radiant-textile_filter-extension",      "~> 1.0.4"

  # additional extensions
  gem "radiant-index_page-extension",          "~> 1.0.1"
  gem "radiant-vapor-extension",               "~> 2.1.4"
  gem "radiant-reorder_children-extension",    "~> 1.0.6"
  gem "radiant-layouts-extension",             "~> 1.1.3"
  gem "radiant-sibling_tags-extension",        "~> 0.2.1"
  gem "radiant-if_param_tags-extension",       "~> 1.0.1"
  gem "radiant-cache_buster-extension",        "~> 0.0.1"

  # forked extensions
  gem "radiant-sheets-extension",              "1.1.0my1"
end

我试过的东西：
- 将newrelic的需要代码移动到config.ru的顶部和底部。
- 将gem "newrelic_rpm"移至我的Gemfile的顶部和底部（底部为：https://newrelic.com/docs/ruby/does-new-relic-work-with-the-bundler-gem）
- 将newrelic的需求代码移至:rails_root/config/enivornments/[RAILS_ENV].rb
- 移动newrelic需要代码到:rails_env/config/boot.rb和:rails_env/config/environment.rb - 顶部和底部。
- 使用newrelic_rpm

有人有什么想法吗？

谢谢！

与NewRelics支持人员合作后，他们让我发了这篇文章：http://newrelic.github.com/rpm/NewRelic/Agent/Instrumentation/Rack.html。

然后，我稍微解构了这个方法并提出了以下解决方案：

带有Memcached的Radiant和NewRelic不会记录流量
