efficient-logging

C++ logging library. It is powerful, supports asynchronous low latency, extendable, light-weight, fast performing, thread and type safe and consists of many built-in features. It provides ability to write logs in your own customized format. It also provide support for logging your classes, third-party libraries, STL and third-party containers etc.

zilog: Zero Impact Log, it allows your program to drop low priority logs to ensure a required capacity when CPUs are busy, it also provides a much higher log capacity than other log libraries, because, It is a high performance, asynchronized, thread-safe (uses atomic API to synchronize) log library for C/C++, it directly dumps argument list rather than printing formatted string. Currently, it supports 64bit Linux only, for C++ it doesn't support "<<" operation, only supports printf arguments format.
