This chapter describes how to use the NMS configuration manager (NMMGR) to create or modify a configuration file for logging. Basic information about NMMGR is contained in Using the Node Management Services Utilities (32022-61005); if you are not familiar with NMMGR, you should read that manual before continuing. Note that the logging configuration is completely HP 3000 dependent and has no corresponding remote system configuration.
Once you have configured the SNA node, you must configure logging. Logging records events such as errors and console commands, and is configured according to subsystems. Within each subsystem, different classes of events (such as internal errors) exist. You specify where you want logging recorded for each of the classes in the subsystem: to a disk file, the HP 3000 console, or the logon device of a UserName.AccountName. If you configure a logging class so that logging is recorded to a UserName.AccountName, that user will receive logged messages any time that UserName.AccountName has an active session.
These topics are covered in this chapter:
Configuration file validation
Configuring logging
"HP-IBM Configuration" screen
"IBM Logging Configuration (1)" screen
"IBM Logging Configuration (2)" screen
"IBM Logging Configuration (3)" screen
Enabling users for a specific subsystem and class
Table 3-1 provides a summary of the logging classes for which configuration is described in this chapter, and guidelines for those configurations. For more information about logging, see chapter 5 of this manual.

 | NOTE: If very high volumes of logging are recorded to the console or a set of users, system performance might degrade. So, the Hewlett-Packard recommended configuration should be followed unless you are advised otherwise by your Hewlett-Packard support contact. |
