Problem of the Disk Latency Analysis in PAL report

Jan 21, 2011 at 1:09 AM

I have  a server that its logical volumes are that:

- HarddiskVolume2
- W:
- V:
- U:
- O:
- N:
- K:
- G:
- D:
- C:

I use the default QuickSystemOverview.xml to generate the report, I have found that the volumn V: and W: were missing in the chart in LogicalDisk Read Latency Analysis, LogicalDisk Write Latency Analysis, PhysicalDisk Read Latency Analysis and PhysicalDisk Write Latency Analysis, but the Overall Counter Instance Statistics could list the V: and W: as below:

 

Condition \LogicalDisk(*)\Avg. Disk sec/Read Min Avg Max Hourly Trend Std Deviation 10% of Outliers Removed 20% of Outliers Removed 30% of Outliers Removed
OK HarddiskVolume2 0 0 .007 0 .001 0 0 0
Greater than 15ms logical disk READ response times /W: 0 .001 .018 0 .003 0 0 0
Greater than 25ms logical disk READ response times /V: 0 .003 .144 0 .014 0 0 0
Greater than 25ms logical disk READ response times /U: 0 .009 .131 0 .016 .005 .004 .002
OK /O: 0 .001 .015 0 .003 0 0 0
Greater than 25ms logical disk READ response times /N: 0 .003 .107 0 .012 0 0 0
Greater than 25ms logical disk READ response times /K: 0 .002 .142 0 .013 0 0 0
Greater than 25ms logical disk READ response times /G: 0 .003 .094 0 .011 0 0 0
OK /D: 0 0 .011 0 .001 0 0 0
Greater than 15ms logical disk READ response times /C: 0 .003 .021 0 .005 .001 .001 0


Is it any limitation about generating the chart? like the number of voulmn? Please help. Thank you.

Forgot to mention, it is the PAL v2.0

The chart and the stats should both have all of the counter instances.

It is odd to see the forward slash in front of the logical disk letters unless you manually removed the computer name. If the problem persists, then please send me your performance counter log (*.blg). My email address is clinth@microsoft.com. Thank you.
