How do you configure ZAP logging

ZAP logs to a file called "zap.log" in the ZAP 'home' directory.

The logging is configured by the log4j.properties file in the same directory.

By default the 'main' logging levels are set to "INFO" by these 2 lines:

log4j.logger.org.parosproxy.paros=INFO
log4j.logger.org.zaproxy.zap=INFO

Changing these to "DEBUG" (and restarting ZAP) will significantly increase the amount of logging performed:

log4j.logger.org.parosproxy.paros=DEBUG
log4j.logger.org.zaproxy.zap=DEBUG
