Stdout.log and Stderr.log¶
When FusionReactor starts it begins intercepting java print messages sent to System.out and System.err. System.out write operations go into stdout.log and System.err operations go into the stderr.log.
This will not include print messages which are written by native libraries.
FusionReactor captures the stdout and stderr from the start of the process but while FusionReactor is starting up it only will store up to 500 lines for each log to write into the FR log directory. Once FusionReactor has fully activated all write operations to System.out or System.err will go into the corresponding log file unless turned off in the Log Settings page.
