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:

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.
