# A nagios/icinga plugin for sending alerts to Slack. See more documentation on the team services page at:
# https://my.slack.com/services/new/nagios
#
# Requires these perl modules:
# HTTP::Request
# LWP::UserAgent
#
# I am not a perl programmer. Beware.
#
# An example Nagios config:
#
# define contact {
#       contact_name                             slack
#       alias                                    Slack
#       service_notification_period              24x7
#       host_notification_period                 24x7
#       service_notification_options             w,u,c,r
#       host_notification_options                d,r
#       service_notification_commands            notify-service-by-slack
#       host_notification_commands               notify-host-by-slack
# }
#
# define command {
#       command_name     notify-service-by-slack
#       command_line     /usr/local/bin/slack_nagios.pl -field slack_channel=#alerts
# }
#
#define command {
#       command_name     notify-host-by-slack
#       command_line     /usr/local/bin/slack_nagios.pl -field slack_channel=#alerts
