Custom JobScheduler Log File Locations
The default location for JobScheduler log files is the ${SCHEDULER_DATA}/logs folder, which is set by the log_dir parameter in the ${SCHEDULER_DATA}/config/factory.ini file.
Administrators are, however, free to specify an alternative location for their JobScheduler log files. In this situation, to ensure that the JOC Cockpit is able to find the alternative log file location, we recommend that administrators do not change the log_dir parameter in the factory.ini file but create a SymLink pointing to the new log directory in place of the default folder specified by the log_dir parameter. The JOC cockpit will then look at the default log file location and follow the SymLink to the new location.
Note that on some Unix systems a SymLink in the ${SCHEDULER_DATA}/logs folder may lead to another location such as /var/logs/sos.
