Capistrano::Logger

Show your logs with Capistrano.

Add this line to your application's Gemfile:

gem 'capistrano-logger', group: :development, github: 'ashlinchak/capistrano-logger'

or:

gem 'capistrano-logger', group: :development

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-logger

Require in Capfile to use it:

require 'capistrano/logger'

Add configuration options for your deployment environment (if you need to change default behavior):

# production.rb

set :logger_default_file, "#{deploy_to}/shared/log/puma_error.log" # default <release_path>/log/<rails_env>.log

set :logger_lines, 500 # default 100

set :logger_file_aliases, {
      puma_err: "#{deploy_to}/shared/log/puma_error.log",
      nginx_err: '/var/log/nginx/error.log'
}

Show last 100 lines from the production.log:

$ bundle exec cap production logger:show

Show last 50 lines from the puma_error.log using logger_file_aliases setting:

$ bundle exec cap production logger:show LINES=50 ALIASE=puma_err

Show last 50 lines from the target file on the server:

$ bundle exec cap production logger:show LINES=50 FILE=/var/log/mysql.log
