How to find Sidekiq is running or not

Question

In one of my project i am using Sidekiq

Is there any inbuilt Sidekiq console method/method that helps me to find whether sidekiq is running or not.

My requirement is kind of a pre check condition where if Sidekiq is not running i will raise a error.

I tried using the grep like

'ps -ef | grep sidekiq'  

but it's not solving my purpose.

The method i am looking for should be something like:

Sidekiq.is_running?  

Thanks in advance.

I also Tried

Sidekiq not running

1.9.3p392 :021 > system 'ps aux | grep sidekiq' ankitgupta      6683   0.0  0.0  2432768    600 s001  R+   11:47AM   0:00.00 grep sidekiq ankitgupta      6681   0.0  0.0  2433432    916 s001  S+   11:47AM   0:00.01 sh -c ps aux | grep sidekiq  => true 

Sidekiq is running

1.9.3p392 :022 > system 'ps aux | grep sidekiq' ankitgupta      6725   0.0  0.0  2432768    600 s001  S+   11:57AM   0:00.00 grep sidekiq ankitgupta      6723   0.0  0.0  2433432    916 s001  S+   11:57AM   0:00.00 sh -c ps aux | grep sidekiq ankitgupta      6707   0.0  1.3  3207416 111608 s002  S+   11:56AM   0:07.46 sidekiq 2.11.2 project_name [0 of 25 busy]    => true  

It is always returning true.. I want to catch the process when it runs

Answer 1

A little trick:

ps aux | grep '[s]idekiq' 

Hope it works

Answer 2

Ideally you can do this directly from ruby itself. Put this in some rake task or standalone script (don't forget to specify Sidekiq connection details)

ps = Sidekiq::ProcessSet.new ps.size # => 2 ps.each do |process|   p process['busy']     # => 3   p process['hostname'] # => 'myhost.local'   p process['pid']      # => 16131 end ps.each(&:quiet!) # equivalent to the USR1 signal ps.each(&:stop!) # equivalent to the TERM signal
