Using the Node Management Services (NMS) Utilities (32022-90053)

Introduction
NMDUMP
NMDUMP
The Node Management Services Trace/Log File Analyzer
(NMDUMP) is the NMS utility that you use to format files created by
the logging and tracing facilities. NMDUMP translates the log and
trace files into a format that is easier to read.
Logging and tracing are diagnostic and debugging services provided by
NMS.
Tracing
Tracing records subsystem calls and/or the sequences of module
execution. Tracing is provided at both the user level and at an internal
level. User-level tracing provides a record of data communications
subsystem intrinsic calls. Internal level tracing records internal state
transitions and the sequences of module execution within data
communications subsystems. It should only be used on the
recommendation of an HP service representative.
Logging
Logging records subsystem events for all data communications links. It
records the usage of the communications network resources and serves
as a tool in resolving network problems.
Logging can be performed at three levels: network logging, event
logging, and link level logging. You choose the level of logging for a
particular system through the NMMGR configuration for that system.
For information on using logging and tracing for NS 3000/iX products,
see the NS 3000/iX Operations and Maintenance Reference Manual.
For information on using logging and tracing for HP-to-IBM products,
see the Node Manager’s Guide for each product. For more information
on NMDUMP, see Chapter 7, “NMDUMP,” of this manual.
