Puma plugin that allows you to define dynamically calculated process titles (tag option) for your workers inside your puma's config.

Installation

gem install puma_dynamic_tags

or:

# Gemfile
gem "puma_dynamic_tags"

bundle install

Usage

Setup your puma application:

# config.ru

# (Sinatra example)
require "sinatra"
run Sinatra::Application

Enable dynamic_tags plugin and configure dynamic tag option:

# config/puma.rb
plugin "dynamic_tags"

# and now you can use dynamic tags:

tag do
  "some_dynamic_result: #{Time.now}" # your dynamic code
end

and then:

# run your puma in your favorite mode
bundle exec puma -t 8:32 -w 3

and then (check your process titles):

puma 5.6.4 (tcp://0.0.0.0:9292) [some_dynamic_result: 2022-04-08 03:01:04 +0300] # (main claster process)
puma: cluster worker 2: 38624 [some_dynamic_result: 2022-04-08 03:02:50 +0300] # <--- dynamic process title
puma: cluster worker 1: 38624 [some_dynamic_result: 2022-04-08 03:02:50 +0300] # <--- dynamic process title
puma: cluster worker 0: 38624 [some_dynamic_result: 2022-04-08 03:02:50 +0300] # <--- dynamic process title

and then (run phase-restart in order to make sure that your workers have a new titles):

puma 5.6.4 (tcp://0.0.0.0:9292) [some_dynamic_result: 2022-04-08 03:01:04 +0300] # (main claster process)
puma: cluster worker 2: 38624 [some_dynamic_result: 2022-04-08 03:03:25 +0300] # <--- each title has been recalculated
puma: cluster worker 1: 38624 [some_dynamic_result: 2022-04-08 03:03:25 +0300] # <--- each title has been recalculated
puma: cluster worker 0: 38624 [some_dynamic_result: 2022-04-08 03:03:25 +0300] # <--- each title has been recalculated

Profit!
