Dspec, L1dcache, L1icache, L2cache, Stall | HP UX Caliper Software

dspec	Provides metrics on the effectiveness of data speculation.
fp	Provides information relating to floating-point operation density, execution
	rate, and flush/trap events density.
l1dcache	Provides miss rate information for the L1 data cache.
l1icache	Provides miss and prefetch usage information for the L1 instruction cache.
l2cache	Provides miss rate information for the L2 unified cache.
	If you specify this event set and you are on an Integrity servers dual-core Itanium
	2 or Itanium 9300 quad-core processor system, it is treated as if you specified
	-m l2dcache,l2icache.
l2dcache	Provides miss rate information for the L2 data cache for Integrity servers
	dual-core Itanium 2 and Itanium 9300 quad-core processor systems.
l2icache	Provides miss rate information for the L2 instruction cache for Integrity servers
	dual-core Itanium 2 and Itanium 9300 quad-core processor systems.
l3cache	Provides miss rate information for the L3 unified cache.
overview	Provides a particular set of metrics, depending on whether you are running
	on an Itanium 2, or a dual-core Itanium 2 or Itanium 9300 quad-core processor
	server.
	Provides these metrics for Itanium 2 Integrity servers:
	•	stall
	•	cpi
	•	dispersal
	•	l1icache
	•	l1dcache
	•	l2cache
	•	tlb
	•	fp
	This is the same as specifying -m
	stall,cpi,dispersal,l1icache,l1dcache,l2cache,tlb,fp
	Provides these metrics for Itanium 2 dual-core and Itanium 9300 quad-core
	processor Integrity servers:
	•	stall
	•	cpi
	•	dispersal
	•	l1icache
	•	l1dcache
	•	l2icache
	•	l2dcache
	•	l3cache
	•	tlb
	•	fp
	This is the same as specifying -m
	stall,cpi,dispersal,l1icache,l1dcache,l2icache,l2dcache,l3cache,tlb,fp
queues	Provides bus request queue (BRQ) metrics that may give some insight into
	possible performance problems related to the system bus.
