InterSystems: The power behind what matters   

Maximum size of the messages log file.
[Startup]    MaxConsoleLogSize=n
The value n is the maximum size of the InterSystems IRIS console file, in megabytes. The console file is messages.log in the InterSystems IRIS system management directory, or the alternate filename.log named by the second piece of the console parameter in the [config] section.
After the console file reaches the size limit of n megabytes, the next InterSystems IRIS startup renames the existing filename.log to filename.old_Date and creates a new, empty InterSystems IRIS console file called filename.log.
Range of Values
1–500 megabytes. The default is 5 megabytes.
Management Portal
On the page System Administration > Configuration > Additional Settings > Startup, in the MaxConsoleLogSize row, select Edit. Enter a number of megabytes.
