Glog
glog is a C++ logging framework designed for recording application events and system diagnostics. It provides a stream-based interface for capturing debugging information and managing system event persistence.
The library includes a stack trace logger that captures execution call stacks and resolves memory addresses into readable function names. It also features a dedicated error handling module to manage system shutdown and reporting during fatal failures.
Log lifecycle management is handled through automatic rotation and deletion of old files to prevent disk space exhaustion. The framework supports custom log routing and output configuration, allowing messages to be directed to specific destinations via filtering flags and custom sinks.
Features
- C++ Logging Libraries - Provides a high-performance logging framework specifically designed for recording diagnostic events in C++ applications.
- Event Logging - Provides utilities for tracking and logging application events using stream-based tools and macros.
- Stream-Based Interfaces - Provides a stream-based logging interface using C++ operator overloading for formatted message buffering.
- Runtime Call-Stack Capturers - Captures active execution frames and resolves raw memory addresses into human-readable function names.
- Fatal Log Cleanup - Executes specific cleanup and final log flushing sequences triggered by fatal logging events prior to system exit.
- Fatal Error Handlers - Implements a dedicated failure handler for managing system shutdown and reporting during critical errors.
- Fatal Failure Sequences - Ships a dedicated failure handler to manage system shutdown and reporting during critical errors.
- Application Log Routing - Directs different categories of internal log messages to multiple destinations using configurable filters and sinks.
- Log Configuration - Includes settings for defining log severity levels, filtering rules, and output destinations for system diagnostics.
- Log Message Filtering - Controls the visibility of log messages at runtime using globally configurable integer thresholds and flags.
- Log Rotation Utilities - Provides utilities for automatically splitting and deleting old log files to maintain a fixed disk space footprint.
- Log Sinks - Implements pluggable log sinks that allow log output to be routed to arbitrary memory locations or files.
- Diagnostic and Error Reporting - Captures detailed stack traces and execution flows to diagnose the cause of application crashes and fatal failures.
- Log Lifecycle Management - Implements controlled removal and rotation of diagnostic log entries to prevent disk space exhaustion.
- Logging Frameworks - Standard C++ logging module.
