## Logwatch Telegram Bot

This repository includes a guide to send the logwatch results to your Telegram Bot.

 

---

 

## Installing

 

### Prerequisites

The following need to be installed:

-   Logwatch
-   Curl

See `Related Links` for more information about how to install and configure logwatch.

 

### Setting up

#### In Telegram

Create a Telegram Bot in order to obtain the `BOT TOKEN` ([More info](https://core.telegram.org/bots#6-botfather)).

Start a conversation with your new Telegram Bot and obtain the `CHAT_ID`. You can obtain the `CHAT_ID` using the telegram API:

```ad-command
~~~bash
curl https://api.telegram.org/bot<BOT TOKEN>/getUpdates
~~~
```

Replace both of them in the [[#Logwatch sh]] script.

&emsp;

#### In your server

Create (if not already created) the `/root/logwatch_bot/logs` and `/var/cache/logwatch/` folders.

Copy the `logwatch.sh` script in `/root/logwatch_bot` folder. Ensure it has execution permissions.

Edit the crontab.

```ad-command
~~~bash
crontab -e
~~~
```

Add the following line to send the logwatch results every day at 8.00 AM.

```ad-command
title: cronjob
~~~bash
0 8 \* \* \* /bin/bash /root/logwatch\_bot/logwatch.sh
~~~
```

&emsp;

### Logwatch.sh

```ad-code
title: logwatch.sh
~~~bash
#!/bin/bash

curl -F chat_id="$chat_id" -F document=@"/root/logwatch_bot/logs/$day-logwatch.txt" https://api.telegram.org/bot$token/sendDocument >/dev/null 2>&1
~~~
```
