Script to post Shinken service notifications into a Slack channel

slack_shinken_services.sh

#!/bin/bash

# This script is used by Shinken to post alerts for services into a Slack channel
# using the slackcli command line. Create the channel, 
# and integration first and then add this notification script in your
# Shinken configuration.
#
# You have to set enable_environment_macros=1 in the shinken.cfg configuration file.
#
# All variables that start with NAGIOS_ are provided by Shinken as 
# environment variables when a notification is generated.
# A list of the env variables is available here: 
#   http://shinken.readthedocs.org/en/latest/05_thebasics/macrolist.html
