FusionLogger-Python

FusionLogger-Python is a centralized logging framework that provides configurable log levels and dynamic scopes for fine-grained control over application logging. It features structured log records, flexible template-based formatting via tokens, and a fluent builder for easy logger configuration.

Features

• Configurable Log Levels: Supports DEBUG, INFO, WARNING, and CRITICAL levels.
• Dynamic Scopes: Easily set and clear logging scopes for contextual logging.
• Flexible Formatting: Customizable output format via token-based formatting; define log formats and datetime formats through string parameters in the formatter constructor.
• Dual Logging Outputs: Supports both console and file logging (file mode: append).
• High Performance: Capable of processing approximately 3000 log messages per second.

Requirements

• Python Versions:
  • Developed under Python 3.12
  • Linted with PyLint under Python 3.8, 3.9, and 3.10
• External Dependencies: None

Installation

Install FusionLogger-Python via pip:

pip install fusion_logger_python

Usage

A simple usage example can be found in the provided TestBenchmark.py file. Here is a brief example of how to initialize and use the logger:

from fusion_logger_python import FusionLoggerBuilder, FusionLogLevel

# Build and configure the logger
logger = FusionLoggerBuilder()
.set_name("MyAppLogger")
.set_min_level(FusionLogLevel.DEBUG)
.write_to_file("app.log")
.build()

# Log messages at different levels
logger.debug("This is a debug message.")
logger.info("This is an info message.")
logger.warning("This is a warning message.")
logger.critical("This is a critical error message.")

Configuration

• Logging Levels:
  Set the minimum output level (e.g., DEBUG, INFO, WARNING, CRITICAL) using the fluent builder.

• Output Formats:
  Specify custom log output formats by passing a format string to the FusionLogFormatter constructor.
  Additionally, provide a custom datetime format string (using datetime.strftime() formatting) if desired.

• File Logging:
  The logger writes log entries to files in append mode. Simply add file paths via the builder methods.

Provided Components

• FusionLogger: Core logging class handling log message creation and processing.
• FusionLoggerBuilder: Fluent builder for easy and chainable logger configuration.
• FusionLogProcessor: Singleton-based processor for handling log records (work in progress for thread safety).
• FusionLogFormatter: Component to format log records based on templates.
• FusionLogRecord: Structured container for all log entry metadata.
• FusionLogLevel: Enum defining available log severity levels.

Performance & Best Practices

For best performance, initialize the logger during application startup. The token-based formatting approach is optimized for high throughput, achieving roughly 3000 messages per second. Note that while the processor's singleton implementation is designed for thread-safe operations, full thread safety is still a work in progress.

Known Issues
