Today I got curious about a simple question: was my iSCSI targetmachine actually running at its full potential read speed?

The machine exports individual disks to its clients, so measuringsingle disk performance wouldn't give me the answer. Summing up IOacross all the disks would have given me a number, but so would justgetting the network bandwidth utilization; if the machine was saturatingits gigabit link, it was clearly running as fast as it could.

There doesn't seem to be a program that will directly

More and more, Solaris 10 strikes me as being much like Ubuntu 6.06: asystem with plenty of big ideas but only half finished implementations.Today's half implemented idea is fmd , the new fault manager daemon .

One of the things I expect out of a fault monitoring system is that itshould not report things as faulted when they are now fine, especiallynot with scary messages that get dumped on the console at every boot(it's acceptable to report them as faulted and now

Before you rise in righteous indignation, let me say that that doesn'tmean that you can't write programs in the Bourne shell; you can writeprograms in anything that's Turing-complete if you try hard enough.It's just that you shouldn't.

The problem with writing programs in the Bourne shell is the same aswriting programs in any other highly constrained language: your programs come out all but unreadablebecause they are spending most of their time getting around the inherentlimitations of their
