CXperf Performance Monitoring Support
This release supports the CXperf performance monitoring utility. CXperf is an optional
product that is scheduled to be available on the HP-UX Application Release 03/2001 and
later releases. This support includes a low-latency interface for monitoring performance.
The interface does not significantly alter the performance of processes that are not being
monitored.
CXperf support includes the ability to gather the following metrics on a per-thread basis:
• Cache latency
• Context switches
• Instruction and data TLB misses
• Instruction cache misses and data cache misses
• Instruction count
• Migrations
• Page faults
• Thread compute (CPU) time
• Wall Clock time
CXperf support provides for per-thread performance counters and a mechanism for
inheriting performance monitors in child processes created via fork. For details, refer to
the cxperf (1) manpage.
