If necessary, you can go back months to confirm a change in resource usage. Moreover, if you keep old logs then you can see precisely when a problem originated. See here for a refresher. The performance monitor log, holds all the counters of all the objects and that you wish to track. The advantages of a log over the System Monitor is that the log captures the data permanently in an actual file.
See Diagram 1 When the dialog box appears, give the log a meaningful name, for example the name of the server or object. The first time you save a log you are prompted to create a folder, accept Perflogs as the directory name. Next you have a choice of button, either click on Add O bjects or click on Add Counters.
Let us begin with Add Objects, because it is simpler and you will not miss any instances. See Diagram 2 An old trick is to use the control key as you pick multiple counters. Setting the time interval is tricky. The trade-off is event accuracy versus log disk space. My advice is to leave the timing at the default 15 seconds — for now.
When you are ready, click the A d d button down at the bottom of Diagram 2. If you make a mistake you can always go back, select the log Properties and adjust the selections. I like the way that as soon as you have finished creating a log, the icon color turns from red to green. You can change the view to graph, report or histogram style, the monitoring time interval and the colour of the counter lines, amongst others.
The above screenshots shows the general tab of the system monitor properties. The performance monitor can be a great tool to help with investigating the performance of your network. You can then compare the collected data and keep it as a record or use it for problem analysis. In my example I have chosen to use the Network Interface as the performance object.
The following counters were added: Current Bandwidth — to display the amount of bandwidth the network interface has. The image below displays a graph of network activity that took place within the space of five minutes. The purple line represents the number of packets per second, the yellow line represents the total bytes per second and the light green line shows how much bandwidth is available.
To simulate this activity I navigated to a share on another computer on the network and browsed through the folders. Performance Logs and Alerts. With the use of logs you are able to capture data that you can analyze later. Logged counter data information can be exported to spreadsheets and databases for future review and reporting. Alerts allow you to set an action that will be performed when specified counters reach a given value. These actions include sending a network message, executing a batch file, recording an item in the application log of the event viewer, and to start logging performance data.
Saturday, November 3, PM. For the pal report, it run on any workstation, you just laod the file you saved from perfmon. So, you run the perfmon and select to save to a file for a period X of time, and after you run that tool on another computer to generate a readable report :- MCP MCTS Exchange Server , Configuring Want to follow me?
Proposed as answer by talzayas Wednesday, October 28, PM. Monday, November 5, AM. How can I check logs etc to determine affects after applying updates. Since that time memory wavers between MB. No use of 3rd party apps please. Wednesday, November 7, PM. Use perfmon, activate that counter; Performance Object: Process Counter as Private Bytes Instance as all Make perfmon save to file, and after analyse the perfmon.
Make only one change at a time. If you make too many changes at once, it may be impossible to accurately assess the impact of each change. Many performance problems generate errors that you can display using Event Viewer. After you make a change, you should resume monitoring and compare the before and after data to determine if the change made an impact on the problem.
If you think that performance problems may be due to network components, you can compare the performance of applications run over the network with the performance of locally run applications. The type of performance problems you are having determines the type of corrective action you should take. Let's look at some problems and common performance tweaks you can make. If you set up a counter but receive no data, you should check to see if the counter's associated DLL file has been deleted.
Performance Monitor will not detect if the counter has been deleted once it is in use, but it will continue to report the counter data as zeros.
A counter may also report zeros if you do not have the appropriate permissions with which to monitor the computer.
You'll get an error message when you attempt to set up the counter, but if you ignore the message, it will allow you to proceed. You may notice gaps in your line graphs if the processing activity on a system becomes too heavy. The graphing will resume when adequate resources are available. The graph is also limited to samples, so all values recorded in a log may not appear in the Graph view. If Task Manager shows that a process is running but is still not reporting data, you can use the Exctrlst.
Only bit processes appear in the Instances list.
