If you want to see what arguments are being passed to Sidekiq jobs you can set the SIDEKIQ_LOG_ARGUMENTS [environment variable] (https://docs.gitlab.com/omnibus/settings/environment-variables.html) to 1 (true).
Example:
gitlab_rails['env'] = {"SIDEKIQ_LOG_ARGUMENTS" => "1"}Please note: 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).
