an experimental log aggregator

Primary LanguageRust

Project Structure

  1. Log Collector:

    • Purpose: Collect logs from various sources (files, stdout, etc.).
    • Components:
      • File Watcher
      • Log Parser
      • Log Shipper

  2. Log Storage:

    • Purpose: Store logs in a scalable and queryable format.
    • Components:
      • Database Schema
      • Database Connection
      • Log Inserter

  3. Query Interface:

    • Purpose: Provide an interface to query and visualize logs.
    • Components:
      • HTTP Server
      • Query Endpoints
      • Query Engine

Todo List

1. Set Up Your Rust Project

  • Create a new Rust project using cargo new log_aggregator.
  • Add necessary dependencies to Cargo.toml (e.g., notify, serde, diesel, actix-web).

2. Log Collection

  • Implement a file watcher to monitor log files for changes.
  • Create a log parser to convert raw log data into a structured format.
  • Develop a log shipper to send parsed logs to the storage component.

3. Log Storage

  • Design a database schema for storing logs.
  • Implement database connection logic.
  • Create a log inserter to save logs into the database.

4. Query Interface

  • Set up an HTTP server using actix-web.
  • Define query endpoints to retrieve logs based on criteria (e.g., timestamp, level).
  • Implement a query engine to execute queries against the log storage.

5. Integration and Testing

  • Integrate all components and ensure they work together seamlessly.
  • Write unit tests for each component.
  • Perform load testing to ensure the system can handle high log volumes.

6. Documentation and Optimization

  • Document the code and architecture.
  • Optimize performance bottlenecks.
  • Implement security measures for query endpoints and log storage.

Detailed Design

Log Collector

  • File Watcher:

    • Monitors log files for changes.
    • Uses the notify crate to watch for file events.

  • Log Parser:

    • Parses raw log data into a structured format (e.g., JSON).
    • Uses the serde crate for serialization.

  • Log Shipper:

    • Sends parsed logs to the storage component.
    • Handles retries and error logging.

Log Storage

  • Database Schema:

    • Defines tables and columns for storing logs.
    • Example: logs table with columns id, timestamp, level, message.

  • Database Connection:

    • Establishes a connection to the database.
    • Uses the diesel crate for ORM.

  • Log Inserter:

    • Inserts parsed logs into the database.
    • Handles batch inserts for better performance.

Query Interface

  • HTTP Server:

    • Sets up an HTTP server using actix-web.
    • Defines routes for querying logs.

  • Query Endpoints:

    • Endpoints to retrieve logs based on criteria.
    • Example: /query?level=INFO&start=2023-10-01T00:00:00Z&end=2023-10-01T23:59:59Z.

  • Query Engine:

    • Executes queries against the log storage.
    • Returns results in a structured format (e.g., JSON).

Final Thoughts

Building a log aggregator from scratch is a complex task, but breaking it down into manageable components and following a structured plan will help you succeed. Good luck with your project!
