Problem Check-List Summary
The SCF PROBE PROCESS, $NCP command is useful for displaying the intermediate
nodes in a path and the typical time to each destination node. Example 21-6 shows a
sample display of the SCF PROBE PROCESS, $NCP command.
The (0086) value displayed in this example is calculated in hundredths of seconds
(centiseconds); a time of 0086 is .86 seconds.
Problem Check-List Summary
Table 21-5 summarizes how to use HP utilities to identify network problems.

Utility Information Produced
EMS Events collected by the Event Management Service (EMS) can be
viewed using either the OSM or TSM event viewers.
SCF The Subsystem Control Facility (SCF) catches syntax errors, value
ranges, and incompatible selections in the Expand subsystem
configuration. However, the Expand subsystem usually detects other
types of configuration errors after system load, not when an SCF
command is used.
The SCF LISTDEV or SCF STATUS command can be used to verify
that all Expand line-handler processes are active. You can also use the
SCF LISTDEV command to ensure that the network control process
($NCP) is running.
Measure Measure can be used to make a detailed study of a particular nodes
Expand line-handler processes. You can characterize Expand network
traffic by measuring certain Measure entities.
ASAP The Availability Statistics and Performance (ASAP) monitoring tool
provides graphical and tabular displays of system and network object
performance, object state, and entity threshold information. The
Availability Statistics and Performance Extension (ASAPX) product
integrates and extends ASAP monitoring capabilities to single and
multi-node application environments.
