The logging facilities in JMon are provided by Log4j, a publicly available logging library for Java. These logging facilities are included in
com.apama.util.Logger. See the
API Reference for Java (Javadoc).
Full documentation for Log4j 2 can be found at
https://logging.apache.org/log4j/2.x/.
It is recommended that you do not use the
FATAL or
CRIT log levels provided by the
Logger class, which are present only for historical reasons. It is better to use
ERROR for all error conditions regardless of how fatal they are, and
INFO for informational messages. By default, the JMon classes log at
WARN level. See
Setting correlator and plug-in log files and log levels in a YAML
configuration file for information about configuring log levels in the correlator.
To ensure that the correlator can serialize logging behavior, specify that instances of Logger are static.
