xperf and xcxperf
The xperf and xcxperf utilities enable you to monitor performance and resource utilization
for individual systems. By default, xperf displays enhanced statistics for the processor types
listed in
Table 1-1 (page 20) , and generic statistics for all other processor types.
The xcxperf utility is the HP XC variant of xperf. It uses components of HP XC software and
may not function properly on systems without HP XC software. By default, xcxperf displays
generic statistics for the processor types listed in
Table 1-2 (page 20) .
Figure 1-2 shows an xperf display for an Itanium system. Table 1-4 lists a summary of the
statistics that xcxperf and xcxperf display, and Chapter 7 (page 75) contains detailed lists of
the statistics that xperf and xcxperf report.
