Top 10 Logging Libraries in 2017

Logging is a fundamental part of applications, and every application has a different flavor of logging mechanism. An application log is a file of events that are logged by a software application. It contains errors, informational events, and warnings.

  • Logs save many valuable hours for both the support team or developers.
  • As users execute programs at the front end, the system invisibly builds a vault of event information (log entries) for system administrators and the support team.

Logging usually involves writing text messages to log files or sending data to monitoring applications. There are many logging libraries/frameworks which take few minutes to setup and start logging solution for your projects.

In this article, we will discuss the top 10 Logging libraries, or you can say the most useful libraries which are used in 20107
