Server Monitor

Server Monitor is a lightweight command-line application written in Rust that allows you to monitor the uptime of various servers and applications. It periodically pings the specified servers and displays their status in an easy-to-read table format.

Features

• Monitors the availability of multiple servers and applications.
• Displays the current status of each server along with the last checked timestamp.
• Supports custom intervals for checking server status.
• Color-coded status indicators for active (green) and inactive (red) servers.

Prerequisites

• Rust programming language installed on your machine. You can install it from rust-lang.org.
• Access to the ping command on your operating system (available on most systems).

Installation

1. Clone this repository:

   git clone https://github.com/yourusername/server-monitor.git
   cd server-monitor

2. Build the project:

   cargo build --release

3. The compiled binary will be located in the target/release directory.

Usage

You can run the server-monitor application by executing the compiled binary with the desired arguments. The basic syntax is:

./target/debug/service_monitor --servers server1,app1 server2,app2 --interval <seconds>

Arguments

• --servers (or -s): A list of servers and application names in the format server,app. You can specify multiple pairs. If this argument is omitted, default servers will be monitored.

• --interval (or -i): Sets the interval in seconds for refreshing the status. The default value is 180 seconds.

Example

To monitor Google DNS servers:

./target/debug/service_monitor --servers 8.8.8.8,Google DNS --interval 55

Default Servers

If no servers are specified, the application will monitor the following default servers:

• chat.com - ChatGPT Application: will display inactive b/c sign in reqired
• dns.google - Google DNS Service
• jsonplaceholder - API example

Output Format

The application displays the server statuses in a table format:

+-----------------+----------------------+-------------------------+----------------------+
| Server          | App                  | Result                  | Last Checked         |
+-----------------+----------------------+-------------------------+----------------------+
| chat.com        | Chat Application     | Inactive ●              | 2024-11-30 16:43:17  |
| 192.4.5.11      | Example App          | Unknown ●               | 2024-11-30 16:43:22  |
| jsonplacehol... | REST Api Example     | Active ●                | 2024-11-30 16:43:23  |
| dns.google      | Google DNS Service   | Active ●                | 2024-11-30 16:43:23  |
