org.apache.synapse.mediators.builtin.LogMediator
Logs the specified message into the configured logger. The log levels specify which attributes would be logged, and is configurable. Additionally custom properties may be defined to the logger, where literal values or expressions could be specified for logging. The custom properties are printed into the log using the defined separator (\n, "," etc)
