Server online-status check with reporting to telegram

This simple script uses netcat to check if - for instance - a webserver is running on a server. If the service is not running, it utilizes the telegram bot API for sending a message to inform the operator of the server.

How to

1. Register the bot

Go to the BotFather bot-account and create a bot by writing /newbot. Then, copy the token.

2. Find your chat-id

Send a message to you newly created bot (you can find the link to your bot in the success message sent by BotFather).
