SCF
SCF
The Subsystem Control Facility (SCF) interface to the Expand subsystem provides
several commands to help you determine the normal operation of Expand line-handler
processes.
The SCF STATS command displays Layer 4 and Layer 2 statistical information. The
SCF STATUS command displays information about the status of an object, such as its
state (STOPPED, STARTING, or STARTED).
The SCF LISTDEV command is useful for identifying system components and devices
including Expand line-handler processes and the network control process ($NCP). By
using the TYPE identifier in the SCF LISTDEV command, you can display specific
information about Expand subsystem components. Table 21-1 lists the TYPE identifiers
you can use to show information about Expand subsystem components and related
subsystems.
Additional information about Expand SCF commands is provided in Section 19,
Managing the Network. Syntax information for SCF commands is provided in
Section 15, Subsystem Control Facility (SCF) Commands.
Measure
Measure is an HP tool for monitoring the performance of NonStop S-series servers. In
an Expand network, Measure determines if the network is contributing to a
performance problem. Additional information about Measure is provided in Section 20,
Tuning.
Measure is described in the Measure User’s Guide.
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
