Log Analyzer

This Rust project analyzes log files to provide insights into their content. It can perform the following tasks:

• Count the total number of lines in a log file.
• Count the occurrences of specific keywords within the log file.
• Identify and extract IP addresses from the log file.

Project Structure

log-analyzer/
├── Cargo.lock
├── Cargo.toml
├── src/
│   └── main.rs
└── test_log.log

• Cargo.lock: Auto-generated file that specifies the exact versions of dependencies used.
• Cargo.toml: Project configuration file that defines dependencies.
• src/main.rs: The main Rust source code file.
• test_log.log: A sample log file for testing.

Features

• Line Counting: Efficiently counts the total number of lines in a given log file.
• Keyword Search: Allows you to specify keywords and counts their occurrences throughout the log file.
• IP Address Extraction: Identifies and lists all IP addresses found within the log file.

Getting Started

Prerequisites

• Rust and Cargo installed. You can follow the instructions on the official Rust website to install them: https://www.rust-lang.org/tools/install

Building the Project

1. Clone the repository:

bash
    git clone <repository-url>
    cd log-analyzer
    

2. Build the project:

bash
    cargo build --release
    

Running the Project

1. Run the following command:

bash
   cargo run --release <path-to-log-file> <keyword1> <keyword2> ...
   

The program will print:

• The total number of lines
• The number of occurrences of the keywords
• A list of the ip addresses

For example, to analyze test_log.log for the keywords "error" and "warning":

bash
   cargo run --release test_log.log error warning
   

Example Usage

Assume test_log.log contains the following:

2023-10-27 00:00:00 INFO: System started. IP: 192.168.1.1
2023-10-27 00:00:05 WARNING: Low disk space. IP: 10.0.0.1
2023-10-27 00:00:10 ERROR: Failed to connect. IP: 8.8.8.8
2023-10-27 00:00:15 INFO: System is running.
2023-10-27 00:00:20 ERROR: File not found. IP: 172.16.0.1

Running:

bash
cargo run --release test_log.log error warning

Will output:

Total lines: 5
Occurrences of 'error': 2
Occurrences of 'warning': 1
IP Addresses found: ["192.168.1.1", "10.0.0.1", "8.8.8.8", "172.16.0.1"]
