Installation

Installation and Setup

Notes

The ruby executables are install in path similar to /opt/sensu/embedded/lib/ruby/gems/2.0.0/gems/sensu-plugins-mysql-0.0.4/bin

Troubleshooting

When used in chef, if the dependencies are missing, an error may abort the chef-client run:

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

This may be fixed by installing the mysql client library before the plugin:

# http://serverfault.com/questions/415392/install-mysql-gem-for-use-in-chef-client
package "libmysqlclient-dev" do
  action :install
end

sensu_gem 'sensu-plugins-mysql' do version '0.0.4' end
