long ago i recall a library the collected process usage, memory and
such, in a platform independent way (at least across unices). does
anyone else recall this lib?

gem install sys-proctable

Works on MS Windows, too.

Yes, they left a bunch of that stuff out, or don’t supply it via the
BSD-ish interfaces they’ve got.

Also, some limits you set will have no effect, notably the various
memory size ones.

good to know. now i’m using this, which uses the same shell over and
over rather than starting a new one:

cfp:~ > cat a.rb
require ‘session’ # gem install session

module Process
def self.size pid = Process.pid
@sh = Session.new
@sh.execute “ps wwwaux -p #{ pid }”, :stdout => stdout=[]
vsize, rsize = stdout.last.split(%r/\s+/)[4,2]
end
end

p Process.size

cfp:~ > ruby a.rb
[“31052”, “3388”]
