OSC / moab-ruby

Very basic ruby gem that interfaces with Adaptive Computing's scheduler Moab

Moab

Ruby wrapper for the Moab binaries. It uses the XML output of Moab for easy parsing.

Installation

Add this line to your application's Gemfile:

gem 'moab'

And then execute:

$ bundle

Or install it yourself as:

$ gem install moab

Usage

This gem provides a simple interface to the Moab binaries returning the results in XML format. You first need to define a scheduler server:

require 'moab'

# Define a scheduler server using the default environment
oakley = Moab::Scheduler.new(host: 'oak-batch.osc.edu')

# Define a scheduler server with custom environment
oakley = Moab::Scheduler.new(
  host: 'oak-batch.osc.edu',
  lib: '/opt/moab/lib',
  bin: '/opt/moab/bin',
  moabhomedir: '/var/spool/moab'
)

You can now call any Moab binaries for this given scheduler server:

# Call `mrsvctl` for this Moab server
oakley.call("mrsvctl", "-q", "ALL").xpath("//rsv/@Name").first.value
#=> "my_rsv.832749"

# Call `showq` for this Moab server
oakley.call("showq").xpath('//queue[@option="active"]/@count').first.value.to_i
#=> 639
