There are two environment variables that set several debug settings. The "RSYSLOG_DEBUGLOG" (sample: RSYSLOG_DEBUGLOG="/path/to/debuglog/") +writes (allmost) all debug message to the specified log file in addition to stdout. Some system messages (e.g. segfault or abort message) are not written to the -file as we can not capture them.

LogFuncFlow - print out the logical flow of functions (entering and exiting them)
PrintFuncDB - print the content of the debug function database whenever debug information is printed (e.g. abort case)!
PrintAllDebugInfoOnExit - print all debug information immediately before rsyslogd exits (currently not implemented!)
PrintMutexAction - print mutex action as it happens. Useful for finding deadlocks and such.
NoLogTimeStamp - do not prefix log lines with a timestamp (default is to do that).
NoStdOut - do not emit debug messages to stdout. If RSYSLOG_DEBUGLOG is not set, this means no messages will be displayed at all.
