I was trying to add debugging feature and enable local logging for my opengrok project. I had eddited logging.properties file directly under opengrok work folder. And my indexer's first line as [java -Djava.util.logging.config.file=/opengrok/logging.properties]. The indexer was running well, but I did not see any logging file under my designated location. And my logging.properties file as below:
handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler, java.util.logging.StreamHandler, java.util.logging.SocketHandler, java.util.logging.MemoryHandler
.level= ALL
java.util.logging.FileHandler.pattern = ~/log/FileHandler/opengrok%g.%u.log
java.util.logging.FileHandler.limit = 52428800
java.util.logging.FileHandler.count = 3
java.util.logging.FileHandler.level = ALL
java.util.logging.FileHandler.formatter = org.opengrok.indexer.logger.formatter.SimpleFileLogFormatter
java.util.logging.ConsoleHandler.pattern = ~/log/ConsoleHandler/opengrok%g.%u.log
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = org.opengrok.indexer.logger.formatter.SimpleConsoleFormatter
java.util.logging.StreamHandler.pattern = ~/log/StreamHandler/opengrok%g.%u.log
java.util.logging.StreamHandler.level = ALL
java.util.logging.StreamHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SocketHandler.pattern = ~/log/SocketHandler/opengrok%g.%u.log
java.util.logging.SocketHandler.level = ALL
java.util.logging.SocketHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.MemoryHandler.pattern = ~/log/MemoryHandler/opengrok%g.%u.log
java.util.logging.MemoryHandler.level = ALL
java.util.logging.MemoryHandler.formatter = java.util.logging.SimpleFormatter
org.opengrok.level = ALL
