lograffe is a structured logger for modern C++. It is inspired by logrus and zap, similar libraries for the Go programming language.
lograffe's focus is on being a really fast and reliable structured logger. If you need a traditional logger with printf-like syntax, lograffe probably is not for you.
- header-only library
- convenient syntax for structured logging
- least possible overhead when a log level is not active
- for server applications: per-request log levels and sinks, also for multi-threaded processing within one request
- pluggable JSON, logfmt output formats
- default log level changeable at runtime
- zero-overhead custom log levels
