This procedure is for diagnosing data collection problems where the Counter values you need are not available in the NTSMF data collection file and not visible in System Monitor either. If you are still not able to collect the missing Objects and Counters after you have followed all the steps in this procedure, please contact Customer [...]
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 [...]
Unless you are prepared to deal with much larger Performance Sentry data files than usual, you should use appropriate filter settings when you collect Module data. Collecting the Module information is costly, and the average Windows Server executable routinely loads 50-100 assorted DLLs. Please be careful with this new function and implement a Module filter for all container processes [...]
A performance data Object called Module is created internally, when you include the Module Object in your Data Collection Set (DCS) data definition. Each instance of the Module Object shows a load module name, usually a DLL (dynamically linked library module) that is loaded within the specific process. The Module Object also has a parent [...]
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 [...]
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.
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 [...]
