No, to function properly the Performance Sentry collection service should be set up to run under the LocalSystem (or SYSTEM) account. The LocalSystem (or SYSTEM) account is a built-in account used by many services with an extraordinary level of privileges for accessing local system resources. These include privileges that cannot be granted to any User […]

I’m unable to push a new Data Collection Set (DCS) to a 64 Bit Machine
Situation: Performance Sentry Administration is used to assign Data Collection Sets (DCSs) to machines running the data collection service.

The Registry DCS parameters are written to the Registry key: […]
I do not see a drive letter for some of my logical disks. Instead, I see something that looks like HarddiskDmVolumessystemnameDg0Volume1 instead. What is that all about?
Logical disk information containing “HarddiskVolume…” usually indicates an unformatted partition. Knowledge Base article (Q260834) describes the ‘HarddiskVolume’ label as a volume that has been mounted, but not assigned a drive letter. See http://support.microsoft.com/default.aspx?scid=kb;EN-US;q260834 There is another MS KB entry that specfically discusses “HarddiskDmVolumes” names. See http://support.microsoft.com/?kbid=274311. This It’s type I allowed from do football players […]
I am concerned about the overhead of the diskperf measurements. What does this feature cost?
There is very little overhead involved with the collection of diskperf measurements. We strongly recommend that you enable all disk performance data collection on any system where you care about performance. Even if you don’t care that much about performance, you should turn on Logical Disk reporting at a minimum. The Logical Disk Object contains […]
I see a value of 2.63 in the Ave Disk Queue Length Counter field. How should I interpret this value?
The Ave Disk Queue Length Counter is derived from the product of Avg.Disk sec/Transfer) times Disk Transfers/sec, the average response of the device times the I/O rate. This corresponds to a well-known theorem of Queuing Theory called Little’s Law, which states: N = l * Sr where N is the number of outstanding requests in […]
If I am running multiple instances of SQL Server, how do I figure out which instance of the sqlservr.exe process data maps to which SQL Server instance?
On machines where multiple instances of SQL Server are installed, you will see multiple instances of the sqlservr.exe process running. You will need a procedure for associating the performance data at the SQL Server process level — which provides processor utilization statistics and overall memory consumption — with the SQL Server performance counters for that […]
What do I need to do to monitor my servers running MS Exchange, SQL Server, or IIS?
Everything you need to monitor Windows Servers running MS Exchange, SQL Server, IIS, or any other application is included in Performance Sentry. You only need to assign a Data Collection set (DCS) appropriate to the application that runs on these servers to start gathering data on these applications.

There are several ways to approach this. To help you get […]
What User Rights and Permissions does the User Account that I will run the Performance Sentry Collection Service under require?
OK, you asked for it. If you do not need to gather Module identification information, you can run the Performance Sentry collection service under a User Account. You can only set the Collection Service to run under a User Account manually using the Services Administrative Tool, which is illustrated below: To function correctly, the User Account […]
