HP UX IPFilter Software manual Traps Measurement Report Description

Table 33 Information in scgprof Measurement Report: Children Listings (continued)

Column	Description
Children	Name of this child function.
Cycle	Cycle that this child is a member of, if any.
	The cycle as a whole is listed with the same fields as a function entry. Beneath it are listed
	the members of the cycle, and their contributions to the time and call counts of the cycle.
	Above it are listed the non-member functions that called the different members of this cycle,
	the number of hits propagated to every one of these callers, and the call counts for every
	one of these callers from outside the cycle.

*Static-only parents and children are indicated by a call count of 0.

**This field is omitted for parents, or children, in the same cycle as the function. If the function, or child, is a member of a cycle, the propagated times and propagation denominator represent the self time and descendant time of the cycle as a whole.

traps Measurement Report Description

Available only on Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processor systems.

With the traps measurement, produced by the traps measurement configuration file, HP Caliper collects and reports a profile of traps, interrupts, and faults.

The trap profile is produced by statistical sampling of the execution trace buffer (ETB) configured to capture all changes to/from privilege level 0. By default, the traps measurement samples the ETB at every 1,000 CPU cycles, with a variation of 5 percent, and a threshold of 0.

You can change the sampling rate, sampling variation, and threshold with the -speriod option. You should not change the default event (CPU_CPL_CHANGES.LVL0) or the privilege level mask (all).

You can use the --traps-reportedoption to specify which traps, interrupts, and faults are reported. By default, the top 6 traps, interrupts, and faults are reported.

At collection time, information about all 34 traps, interrupts, and faults is collected. The

--traps-reportedoption only dictates what is reported. You can get a report on different traps, interrupts, and faults from the same database, using different caliper report runs.

You can specify the names of from 1 to 6 comma-separated traps, interrupts, and faults. Possible names that you can choose for reporting are:

32INCPT	IA32 Intercept
32INRPT	IA32 Interrupt
ADTLB	Alternate data translation lookaside buffer fault
AITLB	Alternate instruction translation lookaside buffer fault
BREAK	Break instruction fault
DACCS	Data access bit fault
DARGHT	Data access rights fault
DBIT	Data dirty bit fault
DEBUG	Debug fault
DFPREG	Disabled floating-point register fault
DKEY	Data key miss fault
DNTLB	Data nested translation lookaside buffer fault
DTLB	Data translation lookaside buffer fault
FPFLT	Floating-point Fault
FPTRP	Floating-point Trap
GEXCP	General exception:
