+# Sidekiq debugging

+## Log arguments to Sidekiq jobs
+
+If you want to see what arguments are being passed to Sidekiq jobs you can set
+the SIDEKIQ_LOG_ARGUMENTS environment variable.
+
+```
+SIDEKIQ_LOG_ARGUMENTS=1 bundle exec foreman start
+```
+
+It is not recommend to enable this setting in production because some Sidekiq
+jobs (such as sending a password reset email) take secret arguments (for
+example the password reset token).
