Home -> Community -> Mailing Lists -> Oracle-L -> RE: DISK IO?
Also, to monitor Disk IO on NT / W2K you need to have the disk counters turned on.
To check if they are on, use the "diskperf" program, which can check a remote computer.
To turn them on if they are currently off, use diskperf to turn on but they won't come on until the server is rebooted.
Note that under NT / W2K, installing the SNMP service will add in a lot more performance counters.

Satar,
Actually the perfomance monitor can accumulate a *lot* of detailed information, far more than you'll every get from vmstat, sar or iostat.
Plus, there's a Perl interface to the perflib.dll that enables you to collect the data anyway you want. It can also be done remotely.
Performance monitoring is one place the M$ didn't skimp.

UNIX:
man iostat
while you're there, checkout:
man vmstat
Windoze 2000:
I think they have something called "Performance
Monitor" in 2000. From what I hear, it isn't helpful.
I think they are trying to resolve the constant system
crashes before they concentrate on "small" things,
such as disk I/O. ;)

Satar
