Monitoring FTAM Performance
Many factors influence the system performance of OSI/FTAM, including the state of an
object, the number of FTAM processes configured, and the location of a process swap
file. This section provides instructions for system managers using SCF to tune system
performance and maintain maximum throughput. Descriptions and examples are
provided to illustrate the following system maintenance tasks:
•

Monitoring Statistics on page 5-7

You can monitor performance using various hardware and software tools, either through
operator-initiated actions or program-initiated actions. Hardware monitoring is
performed using response-time monitors, line monitors, and other hardware monitors to
determine what is happening in the processor or on the communications lines. Software
monitoring tools include traces, SCF, DSM, console messages, Measure, ViewSys, event
messages, and Inspect. Note that the software monitoring tools may, themselves,
negatively affect performance because they use resources that would otherwise be
available to your applications.
This section focuses on the use of SCF for performance monitoring of Tandem FTAM
processes—initiators, responders, and APLMGR. However, the underlying TAPS, TSP,
and NSP processes can also affect the performance of your FTAM application. For
information on performance monitoring of lower-layer processes, see the OSI/AS
Configuration and Management Manual. That manual also provides useful general
guidelines in addition to the guidelines presented here.
In addition to using SCF, you can use the Measure utility to collect and display
performance statistics for Tandem NonStop systems. Measure allows you to determine
information such as process, processor, and disk usage. For more information on how to
use Measure for performance monitoring, see the Measure User’s Guide.
Note. The D43 product version of OSI/FTAM is nativized to take advantage of the features of
RISC processors. This improves its performance in terms of end-to-end throughput and
percentage of CPU utilization.
