4. Fremgangsmåde ifølge krav 1, hvor sporingen omfatter at opdatere en eller flere tællere, og hvor den ene eller flere tællere er specifikke for PCI-funktionen og reflekterer input-/output-trafik associeret med PCI-funktionen.
5. Fremgangsmåde ifølge krav 1, hvor fremgangsmåden endvidere omfatter automatisk at præsentere den sporede information for en bruger hvor sporingen omfatter at opdatere en eller flere tællere, og hvor den automatiske præsentation omfatter periodisk at opdatere en styringsblok tilgængelig for brugeren med værdier fra den ene eller flere tællere.
6. Fremgangsmåde ifølge krav 1, hvor fremgangsmåden endvidere omfatter at bestemme hvorvidt sporing skal udføres for PCI-funktionen, hvor sporing aktiveres på en perfunktionsbasis, og at udføre sporingen som reaktion på bestemmelsen af at sporingen skal udføres.
7. System omfattende organ indrettet til at udføre alle trinnene i fremgangsmåden ifølge et hvilket som helst af de foregående krav.
8. Computerprogram omfattende instruktioner til udførelse afalle trinnene i fremgangsmåden ifølge et hvilket som helst af de foregående fremgangsmådekrav, når computerprogrammet udføres på et computersystem.
