Script for telegram notification

[psztoch]

Describe the solution you'd like

Ready for use script /etc/icinga2/scripts/telegram-host-notification.sh and
/etc/icinga2/scripts/telegram-service-notification.sh.

Updated /etc/icinga2/conf.d/commands.conf.

Is your feature request related to a problem? Please describe.

I believe that Telegram is so popular that it is worth including this script in the official distribution along with "object NotificationCommand".

Telegram is indeed very nice but here are some things to consider

• messages by bots do not include end-to-end encryption
• you are trusting a third party with no Data Processing Agreement with you alert data.
• If you are not paying for it you are the product, not the customer

I would second @moreamazingnick's opinion. Personally I would not use Telegram for sensitive information, or anything at all.

Furthermore, there are already lots of notification plugins out there. Please use some of those scripts, as adding this additional maintenance to the main Icinga 2 repository should not be worth the effort.

A plugin for several of the most popular messengers should be in the main repo and standard package.
The lack of a plugin for Telegram is a problem that is definitely worth solving.
Icinga has great monitoring but poor reporting and average notifications.
