This modify from https://github.com/matriphe/monit2telegram/ and custom it for personal needs. So only made for ping and url/http/https checking.

Requirements

• Bash
• CURL
• jq
• Telegram Bot

Create Telegram Bot

If you don't have a Telegram Bot, just create one. By using a Telegram bot you don’t have to use a real Telegram client or reuse your Telegram account.

Getting Bot Token

You will get a Telegram Bot Token after bot created. Keep this token, we will use it later. The bot token is looked like this.

123456789:aBcDeFgHiJkLmN-OpQrStUvWXyZ12345678

Getting Chat ID

To send messages to a Telegram chat, you must first needs to start a chat with the bot. Clicking on the bot link after creation should be enough, it will automatically send a message of /start to the bot.

To get the Chat ID from Telegram bot, execute this command using getUpdates function of Telegram API.

$ curl --silent "https://api.telegram.org/bot{TOKEN}/getUpdates" | jq
{
  "ok": true,
  "result": [
    {
      "update_id": 17082016,
      "message": {
        "message_id": 17,
        "from": {
          "id": 22031984,
          "first_name": "User"
        },
        "chat": {
          "id": 22031984,
          "first_name": "User",
          "type": "private"
        },
        "date": 1471402800,
        "text": "Hello from the other side~"
      }
    }
  ]
}

In this example the Chat ID to look out for is 22031984. Replace {TOKEN} with your Telegram bot token.
