lita-nagios

Build Status Coverage Status

lita-nagios is a handler for Lita that allows interaction with Nagios monitoring solution. It listens for notifications on a HTTP endpoint and uses nagiosharder to send commands to the Nagios instance.

Note: Colors in notifications are not enabled yet, because it relies completely on the adapter and no abstraction layer is implemented nor designed as of now.

Add lita-nagios to your Lita instance's Gemfile:

gem "lita-nagios"
