Send lightweight notifications from scripts
Sometimes you might need to notify someone from a script. Traditionally, this was done by sending emails. However, sometimes e-mails might end up being too much noise if you send them to everybody involved, so that's where this small utility comes in: It allows you to push notifications into some channel on your internal chat system (at the moment, only Slack is supported).
Create a config file (per default /etc/sendmsg.yml) containing the backend to use and it's configuration, like this:
backend: slack
webhook: https://hooks.slack.com/services/something/secret/changeme
Afterwards, you can send notifications using the simple frontend like this:
# ./sendmsg simple -help
Usage of simple:
-body string
The body of the message to send
-cfg string
Path to sendmsg config (default "/etc/sendmsg.yml")
-color string
The color of the message to send
-fields value
A comma seperated list of fields (name:text) to be added
-head string
The header of the message to send (required)
-title string
The title of the message to send (required)
-title_url string
The url of the title of the message to send
Additionally, there are the icingaHost and icingaService frontends that are designed to be drop-in replacements for the normal Icinga2 mail notification scripts. You just do e.g. sendmsg icingaService "$@" in /etc/icinga2/scripts/mail-service-notification.sh and sendmsg will parse and format all fields automatically.
