| # This script is used by Nagios to post alerts into a Slack channel | |
| # using the Incoming WebHooks integration. Create the channel, botname | |
| # and integration first and then add this notification script in your | |
| # Nagios configuration. | |
| # | |
| # All variables that start with NAGIOS_ are provided by Nagios as | |
| # environment variables when an notification is generated. | |
| # A list of the env variables is available here: | |
