Question

我习惯使用delayed_jobs方法进入控制台查看队列中的内容，以及在需要时清除队列的难易程度。 Sidekiq中有类似的命令吗？谢谢！

Answer 1

符合人体工程学API for viewing and managing queues。

默认情况下不需要。

require 'sidekiq/api'

以下是摘录：

# get a handle to the default queue
default_queue = Sidekiq::Queue.new 

# get a handle to the mailer queue
mailer_queue = Sidekiq::Queue.new("mailer") 

# How many jobs are in the default queue?
default_queue.size # => 1001

# How many jobs are in the mailer queue?
mailer_queue.size # => 50

#Deletes all Jobs in a Queue, by removing the queue.    
default_queue.clear

您还可以获得一些摘要统计信息。

stats = Sidekiq::Stats.new

# Get the number of jobs that have been processed.
stats.processed # => 100

# Get the number of jobs that have failed.    
stats.failed # => 3

# Get the queues with name and number enqueued.
stats.queues # => { "default" => 1001, "email" => 50 }

#Gets the number of jobs enqueued in all queues (does NOT include retries and scheduled jobs).
stats.enqueued # => 1051

Answer 2

我从来没有使用过Sidekiq，因此有可能只有查看排队作业的方法，但它们实际上只是Redis命令的包装器，因为基本上所有Sidekiq（和Resque）都是：

# See workers
Sidekiq::Client.registered_workers

# See queues
Sidekiq::Client.registered_queues

# See all jobs for one queue
Sidekiq.redis { |r| r.lrange "queue:app_queue", 0, -1 }

# See all jobs in all queues
Sidekiq::Client.registered_queues.each do |q|
  Sidekiq.redis { |r| r.lrange "queue:#{q}", 0, -1 }
end

# Remove a queue and all of its jobs
Sidekiq.redis do |r| 
  r.srem "queues", "app_queue"
  r.del  "queue:app_queue"
end

不幸的是，删除特定的工作要困难得多，因为您必须复制其确切的值：

# Remove a specific job from a queue
Sidekiq.redis { |r| r.lrem "queue:app_queue", -1, "the payload string stored in Redis" }

您可以通过redis-cli

更轻松地完成所有这些操作

$ redis-cli
> select 0 # (or whichever namespace Sidekiq is using)
> keys * # (just to get an idea of what you're working with)
> smembers queues
> lrange queues:app_queue 0 -1
> lrem queues:app_queue -1 "payload"

Answer 3

如果有任何预定的工作。您可以使用以下命令删除所有作业：

Sidekiq::ScheduledSet.new.clear

如果您要删除所有作业的队列，可以使用以下命令：

  Sidekiq::Queue.new.clear

重试作业也可以通过以下命令删除：

Sidekiq::RetrySet.new.clear

Answer 4

有一个用于访问有关工人，队列和工作的实时信息的API 访问https://github.com/mperham/sidekiq/wiki/API

Answer 5

解决方法是使用测试模块（需要'sidekiq / testing'）并排空工作人员（MyWorker.drain）。

Answer 6

如果你想清除sidekiq重试队列，就是这样：Sidekiq::RetrySet.new.clear

Answer 7

$ redis-cli
> select 0 # (or whichever namespace Sidekiq is using)
> keys * # (just to get an idea of what you're working with)
> smembers queues
> lrange queue:queue_name 0 -1 # (queue_name must be your relevant queue)
> lrem queue:queue_name -1 "payload"

Answer 8

默认队列中有“工人”被绞死，我可以通过网络界面看到它们。但如果我使用Sidekiq :: Queue.new.size

，它们无法从控制台获得

irb(main):002:0> Sidekiq::Queue.new.size
2014-03-04T14:37:43Z 17256 TID-oujb9c974 INFO: Sidekiq client with redis options {:namespace=>"sidekiq_staging"}
=> 0

使用redis-cli我能够找到它们

redis 127.0.0.1:6379> keys *
    1) "sidekiq_staging:worker:ip-xxx-xxx-xxx-xxx:7635c39a29d7b255b564970bea51c026-69853672483440:default"
    2) "sidekiq_staging:worker:ip-xxx-xxx-xxx-xxx:0cf585f5e93e1850eee1ae4613a08e45-70328697677500:default:started"
    3) "sidekiq_staging:worker:ip-xxx-xxx-xxx-xxx:7635c39a29d7b255b564970bea51c026-69853672320140:default:started"
    ...

解决方案是：

irb(main):003:0>  Sidekiq.redis { |r| r.del "workers", 0, -1 }
=> 1

同样在Sidekiq v3中有一个命令

Sidekiq::Workers.new.prune

但由于某种原因，那天它对我不起作用

Answer 9

清除所有sidekiq队列的Rake任务：

namespace :sidekiq do
  desc 'Clear sidekiq queue'
  task clear: :environment do
    require 'sidekiq/api'
    Sidekiq::Queue.all.each(&:clear)
  end
end

用法：

rake sidekiq:clear

是否有控制台命令来查看队列中的什么以及清除Sidekiq中的队列？
