Hello: We measure "disk IO" for all Windows machines in our system today. The counters under "Logical Disk" will give you everything you need. I believe the ones you are interested in are: Physical Disk(Total_)/Disk Reads\sec -> That is read IOPS Physical Disk(Total_)/Disk Writes\sec -> That is writte IOPS You can also get statistics per disk instead of totals: Physical Disk(C:)/Disk Reads\sec Physical Disk(O:)/Disk Reads\sec ... Other counters which are interesting to look at: Physical Disk(Total_)/Disk Read Bytes\sec -> Read Bandwidth Physical Disk(Total_)/Disk Writes Bytes\sec -> Write Bandwidth Physical Disk(Total_)/Disk sec\read -> Read latency Physical Disk(Total_)/Disk sec\write -> Write latency Hope this helps. //Marco <div class="gmail_quote">On Thu, Jun 11, 2009 at 6:08 PM, Frater, Greg J <<a href="mailto:GJFRATER@bechtel.com">GJFRATER@bechtel.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi All, We just started monitoring IO on our Windows servers. We measure two PerfMon counters (using the nsclient++ agent). System\File Control Operations/sec Description: File Control Operations/sec is the combined rate of file system operations that are neither reads nor writes, such as file system control requests and requests for information about device characteristics or status. This is the inverse of System: File Data Operations/sec and is measured in number of operations perf second. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval. System\Data Operations/sec Description: File Data Operations/ sec is the combined rate of read and write operations on all logical disks on the computer. This is the inverse of System: File Control Operations/sec. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval. I'm not sure what good thresholds are for these, currently we have a warning at 10000 and critical at 20000 on our test servers. We've had a couple of servers cross those thresholds but I don't have a good sense for what they should be yet. I've never seen any documentation regarding what a Windows box can do (in terms of IO). >From a command line they look like this: check_nrpe -H $HOSTADDRESS$ -c CheckCounter -a "\\System\\File Data Operations/Sec" ShowAll MaxWarn=10000 MaxCrit=20000 Regards, -greg <div><div></div><div class="h5"> -----Original Message----- From: Curtis LaMasters [mailto:<a href="mailto:curtislamasters@gmail.com">curtislamasters@gmail.com</a>] Sent: Tuesday, June 09, 2009 8:15 PM To: Anthony Montibello Cc: Andreas Ericsson; <a href="mailto:Nagios-users@lists.sourceforge.net">Nagios-users@lists.sourceforge.net</a> Subject: Re: [Nagios-users] disk IO for windows?
