Is boost logging thread safe?

Is boost logging thread safe?

The lg will refer to the one and only instance of the logger throughout the application, even if the application consists of multiple modules. The get function itself is thread-safe, so there is no need in additional synchronization around it.

What is Boostlog?

Log. Boost. Log is the logging library in Boost. For example, there is a front-end that uses a thread to forward log entries asynchronously. …

What is c++ logger?

Plog is a C++ logging library that is designed to be as simple, small and flexible as possible. It is created as an alternative to existing large libraries and provides some unique features as CSV log format and wide string support.

Is boost log header only?

3 Header-Only Libraries. Most Boost libraries are header-only: they consist entirely of header files containing templates and inline functions, and require no separately-compiled library binaries or special treatment when linking. The only Boost libraries that must be built separately are: Boost.

What is log4cplus?

log4cplus is a simple to use C++ logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration. It is modelled after the Java log4j API.

What is Log4cpp?

Log4cpp is library of C++ classes for flexible logging to files, syslog, IDSA and other destinations. It is modeled after the Log4j Java library, staying as close to their API as is reasonable.

What is logging in coding?

In computing, a log file is a file that records either events that occur in an operating system or other software runs, or messages between different users of a communication software. Logging is the act of keeping a log.

Which Boost is header-only?

Most Boost libraries are header-only: they consist entirely of header files containing templates and inline functions, and require no separately-compiled library binaries or special treatment when linking. The only Boost libraries that must be built separately are: Boost. Chrono.

How do you write a logger in C++?

Getting Started Quickly With C++ Logging

1. Create a simple Visual Studio 2019 project.
2. Install the Boost libraries using the NuGet package manager.
3. Learn how to configure log output formatting.
4. Add custom attributes to our logger.

Is log4cplus thread safe?

log4cplus is a simple to use C++ logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration.

When to use a logger in boost.log?

The logger is the component in Boost.Log you will use most often. While you access back-ends, front-ends, and the core only when you initialize the logging library, you use a logger every time you write a log entry. The logger forwards the entry to the core. The logger in Example 62.1 is of the type boost::log::sources::logger.

Which is the smart pointer in boost.log?

The smart pointer is required to register the front-end in the core: the call to boost::log::core::add_sink () expects a boost::shared_ptr. Because the back-end is a template parameter of the front-end, it can only be configured after the front-end has been instantiated. The back-end determines how this is done.

What is the flush call in boost.log?

Example 62.1 calls boost::log::sinks::asynchronous_sink::flush () at the end of main (). This call is required because the front-end is asynchronous and uses a thread to forward log entries. The call makes sure that all buffered log entries are passed to the back-end and are written.

When to use a source specific logger?

These loggers only provide the ability to store source-specific attributes within themselves and, of course, to form log records. This type of logger should probably be used when there is no need for advanced features like severity level checks.
