Change the *.logger.* variable to the new logging level.
In decreasing level of detail, the valid values are ALL (for all messages), DEBUG, INFO, WARN, ERROR, FATAL, and OFF (for no messages). The services or data loaders only log messages of the same or lower level of detail as specified by the *.logger.* variable. Therefore, if you change the log level to ERROR, the service or data loaders will only log ERROR and FATAL messages.
For example, to change the loader controller log files to the ERROR log level:
# Loader controller ("plc") configuration
log4j.logger.com.platform.perf.dataloader=ERROR com.platform.perf.dataloader
