Website Monitoring Service

This project provides an automated service for monitoring websites, checking their HTTP status codes, and sending notifications when websites are down. The service is installed as a Systemd service and runs in the background, periodically checking the status of websites listed in a configuration file. Features

- Monitor multiple websites for availability.
- Log the status of websites to a log file.
- Send notifications (via Telegram or other methods) when a website is down.
- Installed as a Systemd service for automatic startup and management.
- Configurable via a JSON file to easily add and manage URLs.

Prerequisites

- Linux-based system with Systemd support.
- curl installed (for website monitoring).
- jq installed (for parsing JSON configuration).
- Telegram bot setup (if using Telegram notifications).

Installation

To install and set up the website monitoring service, follow these steps:

1. Clone or download the project files

Download the installation script install_monitor_service.sh and place it on your system.

2. Make the installation script executable

chmod +x install_monitor_service.sh

3. Run the installation script

Execute the script to install the service, configuration files, and necessary setup:

sudo ./install_monitor_service.sh

This will:

- Install the website monitoring script.
- Create the sites.json configuration file.
- Set up a Systemd service for the monitoring process.
- Start the service and enable it to run at boot.

4. Customize the configuration file

Edit the sites.json file located at /etc/website-monitor/sites.json to include the websites you want to monitor:

{
    "urls": [
        "https://example.com",
        "https://example.org"
    ]
}

You can add as many URLs as you like to the list.

5. Configure Telegram notifications (optional)

If you want to receive Telegram notifications when a website is down, you'll need to:

- Set up a Telegram bot and get the bot token.
- Set your Telegram chat ID.

Add the token and chat ID to the monitoring script (website_monitor.sh).

Managing the Service

After installation, the monitoring service will automatically start. You can manage the service with the following Systemd commands: Check the status of the service:

sudo systemctl status website-monitor

View logs

Logs are stored in /var/log/website-monitor.log. You can view them with:

sudo tail -f /var/log/website-monitor.log

Restart the service

To restart the monitoring service:

sudo systemctl restart website-monitor

Disable the service

If you want to stop the service from starting at boot:

sudo systemctl disable website-monitor

Manual website check via Telegram (optional)

You can manually check the status of a website by sending a /check command to the Telegram bot. The bot will respond with the HTTP status and description for the provided URL.
