Default: 0
    

ForceContextLogLevelAndTraceStatus¶

Force log level and trace status of contexts to not exceed “ContextLogLevel” and “ContextTraceStatus”. If set to 1 (ON) whenever a context registers or changes the log-level it has to be lower or equal to ContextLogLevel.

Default: 0
    

InjectionMode¶

If set to 0, the injection mode (see here) is disabled.

Default: /tmp
    

OfflineTraceFileSize¶

This value defines the max size of a offline trace file, if offline trace is enabled. This value is defined in bytes. If the files size of the current used log file is exceeded, a new log file is created.

Default: 1000000
    

OfflineTraceMaxSize¶

This value defines the max offline Trace memory size, if offline trace is enabled. This value is defined in bytes. If the overall offline trace size is excedded, the oldest log files are deleted, until a new trace file fits the overall offline trace max size.
