One of the promises of SDN is automated tooling for operational teams and with the NSX API I was quickly able to deliver. nsxchecker accepts a NSX lswitch UUID or a neutron_net_id.

Lots of OpenStack components use a message broker and the most commonly used one among operators is RabbitMQ.

I recommend watching it for OpenStack specific monitoring and a little context around this post. In this post I am going to discuss how the sausage gets made - how the underlying Nagios configuration is managed....
