pyng
Pyng is a bare-bones uptime monitor relying on a Telegram bot for notifications.
It requires Python 3 and the requests module.
Getting started
In order to use pyng, you first need to vitit telegram.me/botfather and type /newbot to create a bot. You should get a reply that asks you to choose a name for your bot. You can name it whatever you want. BotFather will then ask you to pick a username for your bot. Bot usernames have to end in bot. From now on I'll refer to it as <your-bot-username> BotFather will now send you a "Congratulations" message, including your bot's token. I'll refer to that as <your-bot-token>.
Visit t.me/<your-bot-username>, or search for @<your-bot-username> in any Telegram client to start a conversation with your bot. Press the /start button at the bottom of the chat window.
Now visit https://api.telegram.org/bot<your-bot-token>/getUpdates. Try to locate this section of the JSON-formatted text:
"chat":{"id":XXXXXXXXX,
I'll refer to that number as <your-chat-id>.
Now open pyng.py with your favorite editor and replace these constants with your info:
SITE = '<url-of-the-site-you-want-to-monitor>'TOKEN = '<your-bot-token>'CHAT_ID = '<your-chat-id>'
That's it! Now you need to find a way to run pyng periodically. I've scheduled a cron job to run it every minute, like this:
* * * * * python3 /path/to/pyng/pyng.py
Now pyng will inform you every time your site goes down and when it comes back up!
