What gets entered into logs is up to you. There are two dimensions to what produces log content. The loglevel records ascending levels of operational information from nothing to everything. The logFiltersAccept let you control whether each information type created by each of the process reporting mechanisms is accepted into the logs. The resulting logs meld entries from both dimensions sequentially, and record all the information into log files.
Log Level
The loglevel specifies the depth of detail in standard logging. When set to OFF, no log entries are produced. Each higher level enables log entries triggered for that level, as well as each lower level. Set your preferred log level by uncommenting the line # loglevel= in brms.properties, and then setting the value to exactly one of:
OFF - Turn off all logging
ERROR - Log only errors
WARN - Log all errors and warnings
INFO - Log all info, warnings and errors (Default value)
DEBUG - Log all debug information and all messages applicable to INFO level
TRACE - Equivalent to DEBUG plus some tracing logs
ALL - Maximum detail
Note: The loglevel can be changed using the method ICcServer.setLogLevel(String).
Log Filters
The logFiltersAccept setting lets you include specified types of information emanating from running services in the logs. When the log level is set to INFO or higher, this property acepts logging of information types that are listed. Set your preferred log filters by uncommenting the line # logFiltersAccept= in brms.properties, and then listing functions you want to have in logs as comma-separated values from the following:
RULETRACE - Records performance statistics on rules
DIAGNOSTIC - Records of service performance diagnostics at a defined interval (default is 30 seconds)
TIMING - Records timing events
INVOCATION - Records invocation events
VIOLATION - Records exceptions
INTERNAL - Records internal debug events
SYSTEM - Records low-level errors and fatal events
The default logFiltersAccept setting is: DIAGNOSTIC,SYSTEM
OFF - Turn off all logging
