Logging Levels
Logging levels determine how much debug information is stored in the platform.log file for each
package. Levels are set through use of a hexadecimal number between 0x0000 and 0xFFFF. 0x0000 is
the lowest level, and switches off logging for a particular package. 0xFFFF is the highest logging level.
Note We strongly recommend that you set all packages to log level 0x0000 in a live network. Set them to
higher levels only when you debug on an offline network.
Setting Logging Levels
The set-log MML command dynamically alters the log level setting during the execution of the system.
However, the set-log MML command does not affect the logging level of any current MML processes.
For more information about the set-log command, see Appendix A, “MML User Interface and Command
Reference.”
Note The enabling of logging severely impacts HSI performance. We recommend the HSI be running at less
than 2 calls per second when you enable logging. Logging will be automatically disabled when the HSI
enters overload level 3. You can reenable logging when the HSI exits overload.
