Good ole sar and friends have been ported to Linux. Sebastian Godard did the work and bundled it up with a grundle of other stuff in sysstat: http://perso.wanadoo.fr/sebastien.godard/ I don't think it is quite the same as the sar we know and love from the various *nixen, but perhaps it will prove useful. I know there are some kernel patches floating about that improve the quality of performance monitoring.
