Detailed Description

Numbers designating the level of logging output.

Priorities TRACE to VERBOSE are appropriate when all parallel processes contribute log messages. INFO and above must not clutter the output of large parallel runs. STATISTICS can be used for important measurements. PRODUCTION is meant for rudimentary information on the program flow. ESSENTIAL can be used for one-time messages, say at program startup.
