Default Model Logger

This instrument intercepts the log messages and sends them to a named file. After the file reaches a maximum size, it is backed up. The number of backups can be configured. By default, this instrument attaches to all the models in the runtime. When configured programmatically, you can specify which log streams go to which file. In the IDE, all the streams go to a single file.


  • MaxFileSize: in megabytes before the file is backed up and a new file created.
  • NumberOfBackups: the number of backups to retain.
  • all: what filename to send all the streams to.
