Network Monitor Tool

This is a Network Monitor Tool that pings a specified host at regular intervals and executes a predefined command if the host becomes unreachable for a given number of consecutive failures.

Features

• Customizable Ping Interval: Specify the interval between pings in milliseconds.
• Max Failure Threshold: Set the maximum number of consecutive ping failures before triggering the command.
• Ping Timeout: Configure the time to wait for a ping response.
• Unprivileged Mode: Option to run ping in unprivileged mode.
• Cooldown Period: Define a cooldown period after the command is executed before starting to ping again.
• Logging: Provides detailed logging with timestamps, errors, and information messages.

Installation

1. Clone the repository:

   git clone <repository-url>
   cd <repository-directory>

2. Build the application:

   go build -o network-monitor

Usage

Run the executable with the required parameters:

./network-monitor [OPTIONS] COMMAND...

Options

• --interval: Interval in milliseconds between pings (default: 3000 ms).
• --max-failures: Maximum number of consecutive ping failures before running the command (default: 5).
• --host: Hostname to ping (IP address recommended, default: 1.1.1.1).
• --timeout: Timeout in milliseconds for each ping (default: 1000 ms).
• --unprivileged: Run ping in unprivileged mode.
• --cooldown: Cooldown period in milliseconds after running the command before pinging again (default: 300000 ms).

Positional Arguments

• COMMAND: The command to execute if the max failures threshold is reached. Pass the command and its arguments as positional arguments.

Example

To ping 8.8.8.8 every 3 seconds and run echo 'Host unreachable' if it fails to ping successfully 5 consecutive times:

./network-monitor --host 8.8.8.8 --interval 3000 --max-failures 5 --timeout 1000 --cooldown 60000 echo Host unreachable

Logging

Logs are printed to the console with timestamps and include information on:

• Successful pings
• Ping failures
• Command execution status and output
