97 Higher log level numbers imply the most verbosity (expect higher tracing
98 throughput). Log levels 0 through 6 and log level 14 match
99 <a href="http://man7.org/linux/man-pages/man3/syslog.3.html" class="ext">syslog</a>
100 level semantics. Log levels 7 through 13 offer more fine-grained
101 selection of debug information.
