rails puma - command without config file - path to error log?

Question

I am running puma like this:

puma -e production -b unix://blahblah.sock 

setting up configs etc going to take a little more time, so I want to put into production using this. Ofcourse, using nginx.

Where can I find error logs ?

Or any other command to include for error logs to work ?

It's a good practice to create config/puma.rb file, where you can manage related configuration settings.

Set up puma

Puma can be configured just by providing command-line arguments, but it's more convenient to bake the configuration settings into a configuration file and then provide that file with a single -C command line directive. A simple puma.rb that works with MRI Ruby is:

#!/usr/bin/env puma

# start puma with:
# RAILS_ENV=production bundle exec puma -C ./config/puma.rb

application_path = Rails.root
railsenv = 'production'
directory application_path
environment railsenv
daemonize true
pidfile "#{application_path}/tmp/pids/puma-#{railsenv}.pid"
state_path "#{application_path}/tmp/pids/puma-#{railsenv}.state"
stdout_redirect
"#{application_path}/log/puma-#{railsenv}.stdout.log",
"#{application_path}/log/puma-#{railsenv}.stderr.log"
threads 0, 16
bind "unix://#{application_path}/tmp/sockets/#{railsenv}.socket"
