Logs

The system logging feature provides a common way to log the log messages across applications. Each log consists of the following components:

  • Timestamp—Shows the date and time of the log creation.

  • Log message—Shows the message of a specific log.

  • Log level—Shows the level of importance of log message.

  • Log tag—Shows the details of module name, component name, and interface name. A log tag is pre-created and passes during logging.
