如何判断sidekiq是否连接到redis服务器? [英] How to tell if sidekiq is connected to redis server?

问题描述

使用控制台，如何判断 sidekiq 是否已连接到 redis 服务器?我希望能够做这样的事情:

Using the console, how can I tell if sidekiq is connected to a redis server? I want to be able to do something like this:

if (sidekiq is connected to redis) # psuedo code
  MrWorker.perform_async('do_work', user.id)
else
  MrWorker.new.perform('do_work', user.id)
end

推荐答案

你可以使用Sidekiq提供的Redis信息:

You can use Redis info provided by Sidekiq:

redis_info = Sidekiq.redis { |conn| conn.info }
redis_info['connected_clients'] # => "16"

取自 Sidekiq 的 Sinatra 状态应用.
