Detailed Description

Provides logging for bmv2.

Log messages follow the following pattern: <time> bmv2 <msg level> <thread id> <MSG>

Usage:

Logger::get()->info("Hi");
Logger::get()->debug("This is bmv2 amd my name is {}", name_str);
Logger::get()->error("An error? never!");

However, the preferred way to log messages is using the logging macros:

• BMLOG_DEBUG(), or BMLOG_DEBUG_PKT() for messages regarding a specific packet
• BMLOG_TRACE(), or BMLOG_TRACE_PKT() for messages regarding a specific packet
