# CheckTCPMemory This is a simple Nagios/Sensu check that checks that the current TCP memory usage is below the maximum allowed in the Linux kernel. This will find leaking TCP sockets. ## Installation Add this line to your application's Gemfile: ```ruby gem 'check_tcp_memory' ``` And then execute: $ bundle Or install it yourself as: $ gem install check_tcp_memory ## Usage ``` $ check_tcp_memory -h Usage: check_tcp_memory -w <warn percent> -c <critical percent> -w, --warn-percent PERCENT Warning when percentage of total TCP memory is over this threashold. Default: 50% -c, --crit-percent PERCENT Critical when percentage of total TCP memory is over this threashold. Default: 60% -h, --help Show this message --version Show version ``` ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/Altiscale/check_tcp_memory.
