A simple script to send Monit alerts using Telegram bot.

By default, Monit only sends alert notifications via email. But we can also set [a hook to execute a script](https://mmonit.com/monit/documentation/monit.html#action). When executing the script, Monit sets a few environment variables about the alert.

This tiny script transforms those variables into a text message and pipes them to Telegram using a bash script for delivery.

This script is inspired by [Monit2Twilio](https://github.com/alexdunae/monit2twilio).

## Create Telegram Bot

If you don't have a Telegram Bot, just [create one](https://core.telegram.org/bots#create-a-new-bot). 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](https://core.telegram.org/bots/api#getupdates) function of Telegram API.

```ad-command
title: Get Chat ID
~~~bash
curl --silent "https://api.telegram.org/bot{TOKEN}/getUpdates" | jq
~~~
```

 

```ad-code
title: Output
~~~javascript
{
 "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.
