Therefore, it’s best to only add the counters you wish to track.Ĭlicking Add Counters… button will bring up the following screen ( figure 2)īy selecting a performance object from the drop-down list, you can drill down to specific counters and instances of that object.īelow is a list of object counters that make up a good, well-rounded baseline. Adding too many counters by selecting entire objects can easily put undue strain on a server and skew your baseline results. Also, with each additional counter added, the server has to use resources to track that performance data. Granular items (such as Processor\Pool Paged Bytes) will have no bearing on the baseline, so it’s overkill. For a proper baseline, you only need to capture the basic information about the performance of a server. Most of the time, you will find that adding entire objects will result in too much data being collected. You will notice that there are two buttons available – Add Objects and Add Counters. The default screen shows current activity on the system, measuring pages/sec, average disk queue length and processor utilization. You can select the object itself, which includes all counters and all instances of each counter, a specific counter for an object, which includes all instances for that counter, or you can select only to view/track a specific instance of a given counter (for example, instance 0 of the % Processor Time counter of the Processor object). You have the ability to monitor only one instance of a given counter if you wish.Īnother way to look at this relationship is as follows ( figure 1): Using the example above of the processor object, % processor time would have two instances in a dual-processor system – one for each processor (0 and 1). Instances: Each counter can have one or more instances. For example, the Processor object has various counters to choose from: % processor time, % privileged time, % user time, interrupts/second, etc. For any given object, you will have multiple counters. Typical objects include Memory, Network, Paging File, Processor, etc.Ĭounters: Counters are a subset of an object. Objects: Objects are the top-most criteria for monitoring a set of attributes on the server. #Windows server memory monitor how toHowever, to understand how to obtain the information you want, it is important to understand the three fundamental levels of monitoring criteria. #Windows server memory monitor windowsUsing Performance Monitor, performance data can be captured in a variety of granularity, from total processor utilization on a server down to the processor time used by an individual Windows process. This article focuses on using PerfMon to create a performance baseline on a Windows Terminal Server, but the following information also applies to baselining any Windows-based server. However, to meaningfully analyze the PerfMon data captured when troubleshooting performance issues, it is critical that you have a baseline of normal system performance for comparison. Performance Monitor can capture a plethora of information on a Windows Server and is useful in diagnosing performance problems. Windows Performance Monitor (PerfMon) has been around for several generations of Windows and allows you to monitor, either over time or in real-time, the performance statistics of a Windows server. #Windows server memory monitor seriesIf you would like to read the next article in this series please go to Using Windows Performance Monitor to Baseline a Terminal Server (Part 1).
