Terracotta Ehcache logs its messages to the console. Integration Server redirects the Terracotta Ehcache log messages to the ehcache.log file located in the Integration Server_directory \instances\instance_name\logs directory.

Terracotta Ehcache logging has a default configuration, but you can change it by modifying the .tc.custom.log4j2.properties file. This file is located in the Integration Server_directory directory. The logging level is set to Warn. When the logging level is set to Warn, it includes all the Fatal, Error, and Warn messages that are logged by Terracotta Ehcache.
