CXperf Performance Monitoring Support

The HP-UX 11.0 Extension Pack supports the CXperf performance monitoring utility. 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(2). For details refer to the cxperf(1) manpage.

CXperf is an optional product.
