Write to the messages.log file, the operator messages log.
Background Information
InterSystems IRIS reports general messages, system errors, certain operating system errors, and network errors through an operator console facility. On Windows, there is no operator console as such and all console messages are sent to the messages.log file in the InterSystems IRIS system manager directory (install-dir/mgr). For InterSystems IRIS systems on UNIX® platforms, you can send operator console messages to the messages.log file or the console terminal.
For more information, see Monitoring Log Files in the chapter “Monitoring InterSystems IRIS Using the Management Portal” in the Monitoring Guide.
The name of this file is configurable; see Advanced Memory Settings in the Additional Configuration Settings Reference.
