Defining and using machine groups are important features of the Performance Sentry Performance Database (PDB). Machine groups are especially useful in managing the performance data from hundreds or thousands of machines. Additionally, using machine groups improves charting and reporting performance in the Performance Sentry Portal. “A Guide to Using Machine Groups Effectively in the Performance […]

Use DmPerfss.cfg to exclude Performance Library DLLs that cause collection problems
NTSMF version 2.4.6 and higher utilizes a facility that allows you to specifically exclude Performance Library DLLs that cause collection problems. Instructions to exclude specific Performance Library (Perflib) DLLs are contained in an optional configuration file named DmPerfss.cfg that is stored in the NTSMF root directory. The format of theDmPerfss.cfg file, which use a simple XML […]
Help! Do you know if there are any interesting Active Directory Objects or Counters?
NTDS is the main source of information on Active Directory traffic to and from Domain Controllers. It contains a ton of interesting looking counters. Unfortunately, there is not much written that documents AD performance issues and how to use these counters. This TechNet overview article is a good place to start. There are two main […]
Is there a table somewhere that will take the information in the CPU Family field in the NTCONFIG record (i.e., X86 FAMILY 15 MODEL 2 STEPPING 7 ) and convert that to a specific processor chip manufacturer name and model?
The short answer is that Intel knows what these things means, but does not publish a mapping anywhere of how these internal names correspond to external products. The closest Intel comes is this document at http://www.intel.com/design/chipsets/mature/mature.pdf, which does not mention either Family or Stepping names. In semiconductor fabrication, “stepping” refers to the chip manufacturing process […]
Can the Performance Sentry Collection Service impersonate a User Account to gain access to secure network resources?
Yes. By design, the Performance Sentry Collection Service (dmperfss.exe) is installed to run under the built-in LocalSystem (SYSTEM) account. This built-in account, which most services use, has the authority to perform almost any internal function on the local machine. However, the LocalSystem account has no built-in facilities to access secure network resources, such as shared […]
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. An administrator has two options when assigning data collection sets to machines: The first one is called a Registry DCS and the second a File DCS. 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 […]
What key metrics in Windows I should collect and report on?
Once Performance Sentry is installed and you are able to collect and process Windows performance data on a consistent basis, it is a good idea to familiarize yourself with some of the more important data elements that you will be collecting with Performance Sentry. There are several ways to approach this. To help you get […]
