Suggestion for Named Process

Suggestion for Named Process

[Bob McKinven]

Hi,

When running multiple rails apps on the same server it can become a pain identifying which 'unicorn_rails master’ process is running which app (can’t always tell from the user).

My suggestion is for a --name option to allow each process to be named individually.

E.g.  "unicorn_rails —name tiddles_unicorn -D” would show  “tiddles_unicorn master” & “tiddles_unicorn worker[1]” when using PS

I can be cc’d at bob@gigglemania.co.uk.

Cheers.

Bob

I suggest using -c to point to a location specific to the app:

	unicorn -c /path/to/tiddles/unicorn.conf.rb

Having too many options adds to confusion, and changing the executable
name part of the process title can also break tools like killall.

I also end up using something like this quite often (and even without
bundler, just using RubyGems only):

I always recommend using the absolute path for -c, it's less confusing,
especially with options like working_directory and  SIGUSR2 upgrades

(Also, be sure to keep the mailing list Cc:-ed so others can follow).
