What possible reasons can Sidekiq prevent from processing jobs in the queue? The queue is full. The log file sidekiq.log indicates no activity at all. Thus the queue is full but the log is empty, and Sidekiq does not seem to process items. There seem to no worker processing jobs. Restarting Redis or flush it with FLUSHALL or FLUSHDB has no effect. Sidekiq has been started with
bundle exec sidekiq -L log/sidekiq.log
and produces the following log file:
2013-05-30..Booting Sidekiq 2.12.0 using redis://localhost:6379/0 with options {}
2013-05-30..Running in ruby 1.9.3p374 (2013-01-15 revision 38858) [i686-linux]
2013-05-30..See LICENSE and the LGPL-3.0 for licensing details.
2013-05-30..Starting processing, hit Ctrl-C to stop
How can you find out what went wrong? Are there any hidden log files?
The reason was in our case: Sidekiq may look for the wrong queue. By default Sidekiq uses a queue named "default". We used two different queue names, and defined them in config/sidekiq.yml
# configuration file for Sidekiq
:queues:
- queue_name_1
- queue_name_2
The problem is that this config file is not automatically loaded by default in your development environment (unlike database.yml or thinking_sphinx.yml for instance) by a simple bundle exec sidekiq command. Thus we wrote our jobs in two certain queues, and Sidekiq was waiting for jobs in a third queue (the default one). You have to pass the path to the config file as a parameter through the -Cor --config option:
bundle exec sidekiq -C ./config/sidekiq.yml
or you can pass the queue names directly (no spaces allowed here after the comma):
bundle exec sidekiq -q queue_name_1,queue_name_2
To find the problem out it is helpful to pass the option -v or --verbose at the command line, too, or to use :verbose: true in the sidekiq.yml file. Everything which is defined in a config file is of course useless if the config file is not loaded.. Therefore make sure you are using the right config file first.
If you have a config/sidekiq.yml check that all the queues are defined there, check this sample file: https://github.com/mperham/sidekiq/blob/master/examples/config.yml
If you are passing queue names in the command line or Procfile, something similar to
bin/sidekiq -q queue1 -q queue2
bundle exec sidekiq -q queue1 -q queue2
check that all your queues are defined there.
In case you are not sure about the names of your queues, you can figure it out with the following script:
require "sidekiq/api"
stats = Sidekiq::Stats.new
stats.queues
# {"production_mailers"=>25, "production_default"=>1}
Then, you can do things with the queues:
queue = Sidekiq::Queue.new("production_mailers")
queue.count
queue.clear
It took me hours to find out that I had set config.active_job.queue_name_prefix = "xxxxx_#{Rails.env}". The queue names in the settings look the same, but sidekiq looks for the queue with prefix.
Wrong setting
app/jobs/my_job.rb
class MyJob < ApplicationJob
queue_as :default
end
config/sidekiq.yml
:queues:
- default
Correct setting
app/jobs/my_job.rb
class MyJob < ApplicationJob
queue_as :default
end
config/sidekiq.yml
:queues:
- xxxxx_development_default
- xxxxx_production_default
My problem was I had a configure_server but not configure_client in my initialiser, you must have both:
Sidekiq.configure_server do |config|
config.redis = { url: ENV.fetch('SIDEKIQ_REDIS_URL', 'redis://127.0.0.1:6379/1') }
end
Sidekiq.configure_client do |config|
config.redis = { url: ENV.fetch('SIDEKIQ_REDIS_URL', 'redis://127.0.0.1:6379/1') }
end
In my case, sidekiq was fine in development, but stuck in staging. It was human error on the capistrano's deploy configuration. I set the path for sidekiq.yml incorrectly in the Capfile (shared instead of current).
It failed silently:
# Capfile
# WRONG:
set :sidekiq_config, -> { File.join(shared_path, 'config', 'sidekiq.yml') }
^^^^^^^^^^^
# RIGHT:
set :sidekiq_config, -> { File.join(current_path, 'config', 'sidekiq.yml') }
flushing redis worked for me.
WARNING: THIS WILL REMOVE ALL DATA IN YOUR REDIS DATABASE.
redis-cli flushall
I was banging my head against a brick wall on this for a while, my issue was that sidekiq required a newer version of redis-server. I ran "bundle exec sidekiq" and that revealed the error. Once I updated to a newer version of redis-server it was fine.
I just had this issue. Turns out I had made a syntax error in my sidekiq.yml
Spent at least two hours on this as well because queues and configuration and web UI were all fine ... the jobs were just not processed.
My issue was that the sidekiq-server was not running in my docker-compose setup even though it should have been started in the command-section here:
sidekiq:
depends_on:
- 'proddb'
- 'redis'
build: rails-app
--> command: bundle exec sidekiq --environment ${RAILS_ENV} -C config/sidekiq.yml
volumes:
- './rails-app:/project'
- '/project/tmp' # don't mount tmp directory
environment:
- REDIS_URL_SIDEKIQ=${REDIS_URL_SIDEKIQ}
networks:
- backend
My problem was I did not config my initializers/sidekiq.rb properly but even with the correct config, sidekiq was still not running enqueued jobs. I had to run spring stop on top of that and restarted everything and it solved my issue.
I encountered a similar problem wherein the logs would show entries such as INFO Rails : queueing TestWorker (TestWorker). However, the jobs would never get processed, and none of the answers in this question solved the issue.
The tl;dr to my solution is that Sidekiq's Testing Client was getting unexpectedly triggered.
I eventually deduced that there is some "magic" going on underneath the surface that makes it difficult to discretely determine where/when/how the above testing trigger was getting configured, based on the following anecdote...
Running bundle exec sidekiq -C config/sidekiq.yml -e development had the result that Sidekiq::Testing.fake? == true
However, running bundle exec sidekiq -C config/sidekiq.yml -e development_2 had the result that Sidekiq::Testing.fake? == false
^ The only difference between these 2 commands is that I renamed the development environment in sidekiq.yml to development_2, i.e. the same/equivalent environment was running with both commands (at least, presumably it would be the same environment if it wasn't for this inane "magic" under the hood).
I updated sidekiq.rb to explicitly toggle Sidekiq::Testing via the following:
sidekiq_testing_fake = false # set this using env var, etc.
if sidekiq_testing_fake
Sidekiq::Testing.fake!
elsif Sidekiq.constants.include?(:Testing)
Sidekiq::Testing.disable!
end
My issue was that I had both a redis-server running and Redis.app's redis-server running, I killed the redis-server (and kept the Redis.app one)
Im using apn_sender for rails 3 and i have been able to install the gem and get it working just fine by using
rake apn:sender
I have tried to get it started in production mode on a ubuntu box by starting the daemon and it does not seem to work. When i type
script/apn_sender --environment=production --verbose start
I dont see anything. No log present.
when i try to type
script/apn_sender status
It returns with
apn_sender: no instances running
Just trying to understand why it is not running.
i just solved this problem. Try to create a file called 'script' in generators/apn_sender/templates . .
Put this in your script file
# !/usr/bin/env ruby
# Daemons sets pwd to /, so we have to explicitly set RAILS_ROOT
RAILS_ROOT = File.expand_path(File.join(File.dirname(__FILE__), '..'))
require 'rubygems'
require 'apn'
require 'apn/sender_daemon'
APN::SenderDaemon.new(ARGV).daemonize
bash 'rails g apn_sender' in your terminal and will create 'script/apn_server' with same content as above
After that bash this code
./script/apn_server --environment=production --verbose start
it will create log/apn_sender.log . Try running
APN.notify('token',{:alert => '#' , :badge => 1})
or else in rails c to confirm if it works or not , and of course
rake apn:sender
Hope it will help :)
EDIT
You have to install redis and configure
I'm struggling to get delayed_job working under rails 3.0.9 (ruby 1.9.2). The only way I have succeeded to run is to tape manualy the command rake jobs:work.
But I want that to be automatically started when the rails application is starting.
I have installed monit under ubuntu and I configured it to launch a file located in my app. This fails looks like:
check process delayed_job with pidfile /home/me/myapp/tmp/pids/delayed_job.pid
start program = "/home/me/myapp/script/delayed_job start"
stop program = "/home/me/myapp/script/delayed_job stop"
And I added the environment setting in the delayed_job script file:
#!/usr/bin/env ruby
ENV['RAILS_ENV'] = "development"
require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize
When I run the command "sudo monit start delayed_job" I get the following error:
/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- bundler/setup (LoadError)
So I guess it is because sudo is using a wrong version of ruby environment
I tried then the solution of:
rvm monit delayed_job
by adding rvm -S in the start program / stop program lines.
But it still failing with the error : rvm command not found
my rvm dir is located in my home dir /home/me/.rvm
I tried to find workarounds in (sudo changes PATH - why?) to change the PATH environment variable by adding
/usr/bin/env PATH=/home/me/.rvm/bin:$PATH
The command "sudo monit start delayed_job" succeeded! and the worker started.
But the issue is: When I launch sudo /etc/init.d/monit start and when I look to the syslog I still get 'delayed_job' failed to start
So I don't know how to investigate more, how to get more verbose errors for monit.
I have finally succeeded to solve this issue.
I modified the monit file like this:
check process delayed_job with pidfile /home/me/myapp/tmp/pids/delayed_job.pid
start program = "/bin/su - me -c 'cd /home/me/myapp/; script/delayed_job start'"
stop program = "/bin/su - me -c 'cd /home/me/myapp/; script/delayed_job stop'"
I have also downgraded the daemons gem because it seems that there are problems with the latest version. So I'm using now daemons v 1.0.10
I also modified the rights of the log file /home/me/myapp/log/delayed_job.log, because it seems that is was created before my root and my user had no access to it (I had problems to test the command "script/delayed_job start" with "me" user)
This i s the only line that worked for me that read the ENV properly
start program = "/usr/local/rvm/bin/rvm-shell -c 'cd /var/www/[APP]/current/; RAILS_ENV=production bundle exec bin/delayed_job start'"
Hope it helps!
I have a shell script (/home/user/send_report.sh) that runs my rake task:
cd /home/user/rails/app
/home/user/.rvm/gems/ruby-1.9.2-p136/bin/rake report:send
When I run it in console sh /home/user/send_report.sh it works properly.
I am trying to make a cron task with my script: */10 * * * * sh /home/user/send_report.sh, but nothing happens! Rake task should send mail, but this does not happen.
Content of /var/log/cron.log:
Jun 2 21:40:01 ubuntu CRON[1253]: (user) CMD (sh /home/user/send_report.sh)
Jun 2 21:40:01 ubuntu CRON[1251]: (user) MAIL (mailed 240 bytes of output but got status 0x0001#012)
Please, help me to get the working rake script with crontab.
Apart from the fact that you should use /bin/sh, i don't see anything wrong on the cron job. When you run manually, you get the email as you said right ? It does not only work when you do it with cron ? It seems that it could be a misconfiguration of the email server or maybe that the mail server port is blocked ?
Problem was that RVM single-user installation doesn't supports cron tasks. Installed RVM as multi-user and crontab worked properly.
I have set up a cron job, using the great whenever gem.
every 1.minute do
runner "PeerReview.start_feedbacks"
end
I set up the cron job with:
whenever --set environment=development --update-crontab
The crontab file looks fine, it shows:
* * * * * /bin/bash -l -c 'cd /path_to_app/ && script/rails runner -e development '\''PeerReview.start_feedbacks'\'' >> log/cron_log.log 2>&1'
If I execute the runner, it works fine, however, the cron job doesn^t seem to work (also I don't see a log being created).
What am I missing?
(I'm working on Mac OS X, 10.6.6)
update
I think I identified the problem: The path name contains spaces, and this wasn't handled correctly by the whenever gem, the crontab was filled incorrectly (the needed backslashes are missing), so the cronjobs are executed, but the path for the command is wrong.
All above was correctly done.
The rails app was in a directory with spaces in the path names, those spaces were not escaped by the whenever gem, when setting up the crontab.
