Detecting if a process is a runaway if so execute some combination of notify and killing it

Email system utilization statistics in the state prior to correcting the runaway process or starting a dead one

Linux, Ruby, RubyGems Cron (Or some other scheduler)

Tested with:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
ruby 1.9.3p429 (2013-05-15) [x86_64-linux]
rubygems version 1.8.23
rubygems version 2.0.3

$ gem install processwatch

Create a file setup.rb

require 'processwatch'
  include Processwatch_setup
    setup

Run the setup.rb

ruby setup.rb

Configure the configuration files locate in /usr/local/processwatch/conf/

Note you can have multiple services monitored for restart. See example restart configuration file restart_ssh You can add more restart processes with the naming convention restart_uniqueappname (note prefix restart_)

The processwatch executable is /usr/local/processwatch/processwatch.rb you will want to set it on a cron like:

*/5 * * * * /usr/bin/ruby /usr/local/processwatch/processwatch.rb
