Logging

Brian uses the standard Python logging package to generate information and warnings. All messages are sent to the logger named brian or loggers derived from this one, and you can use the standard logging functions to set options, write the logs to files, etc. Alternatively, Brian has four simple functions to set the level of the displayed log (see below). There are four different levels for log messages, in decreasing order of severity they are ERROR, WARN, INFO and DEBUG. By default, Brian displays only the WARN and ERROR level messages. Some useful information is at the INFO level, so if you are having problems with your program, setting the level to INFO may help.

brian.log_level_error()

Shows log messages only of level ERROR or higher.

brian.log_level_warn()

Shows log messages only of level WARNING or higher (including ERROR level).

brian.log_level_info()

Shows log messages only of level INFO or higher (including WARNING and ERROR levels).

brian.log_level_debug()

Shows log messages only of level DEBUG or higher (including INFO, WARNING and ERROR levels).
