boillog

Before cooking, one has to boil something.

BoilLog is a Go package that provides a simple, yet flexible, logging library designed to integrate with Go applications. It supports environmental configuration and includes basic performance profiling and metrics features.

Features

• Environmental Configuration: Customize log location, application name, profiling preference, log level output, and metrics output through environment variables.
• Boilerplate Logging: Simplified logging interface to log messages with minimal setup.
• Performance Profiling: Optional performance profiling to measure and output the execution time of code blocks.
• Memory Usage Metrics: Optional memory usage tracking for performance analysis.

Installation

To install BoilLog, use go get to retrieve the package:

go get github.com/APoniatowski/boillog

Make sure to import the package with:

import "github.com/APoniatowski/boillog"

Usage

Setting Environment Variables

Set the following environment variables to configure BoilLog:

• PROFILER: Set to true to enable performance profiling (default: false).
• METRICS: Set to true to enable memory usage metrics (default: false).
• LOGLOCATION: The directory where log files will be stored (default: /var/log/).
• APP_NAME: The name of the log file (default: boiler.log).

Logging Functions

LogIt

Use LogIt to log messages easily. It takes a log function name, log type, and message as parameters:

boillog.LogIt("MyFunction", "INFO", "This is an informative message.")

Profiling and Metrics

Use TrackTime to measure the execution time of functions and optionally track memory usage:

defer boillog.TrackTime("TaskName", time.Now())
// ... code to profile ...

When PROFILER is set to true, this function will output the elapsed time for the task. When METRICS is set to true, it will also output the memory usage for the task.

Environment Variables

• METRICS: Controls whether memory usage metrics are reported (default: false).
• PROFILER: Controls whether execution time is reported (default: false).
• LOGLOCATION: Sets the directory for log files (default: /var/log/).
• APP_NAME: Sets the name of the log file (default: boiler.log).
