L2dcache,l2icache, L2icache, L3cache | HP UX IPFilter Software

	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
