System hacks: Windows 10 performance data collection without begging

In the process of using the computer, we often need to monitor some data of the system, check the memory usage, see the network speed and so on. To make it easier for you to monitor these data, Windows 10 has a built-in “Performance Monitor” for us to use.

Performance Monitor can monitor components according to our needs, for example, if you want to know how your hard drive is performing. First, type “Performance Monitor” directly in the search box, launch the component and click “+” to add a counter, here the system provides many counters by default, we need to choose the counter according to our actual monitoring needs (Figure 1).


Figure 1 Adding counters

Here we just want to know the performance of our hard disk, so you can select “logicalDisk”, under which there are many other counters, again according to your actual needs. For example, “%Disk Time” is the percentage of time the selected disk drive is busy servicing read or write requests (you can check “Show Description” to see the counter description). So we can select “%Disk Time” here, add it to the list of counters by selecting the C drive and click “Add” to add it to the list of counters to monitor the performance of our system disk (Figure 2).


Figure 2 Selecting the counter

Returning to the Performance Monitor screen, the system will start to monitor the items added above. Here you can see the latest values, average values and other information of the monitored items (Figure 3).

For counter monitoring it takes a period of monitoring to get the results. We can leave the monitor running in the background. At the same time, we can run various common programs in the foreground according to our daily use. By default, the log file for monitoring is saved in the directory “C:PerfLogsAdminNew data collector setComputer name_date”. After a certain period of time, open the log file and select the “%Disk Time” counter in it to view it. Generally speaking, the normal value of “%Disk Time” is <10. Too large a value means that it takes too much time to access the disk, so you can consider increasing memory, replacing the hard disk with a faster one, or optimizing the algorithm for reading and writing data. In this way, with self-defined counters, we can monitor specific system components and make judgments based on the values obtained from the monitoring, thus providing more scientific judgments for hardware upgrades, system optimization, etc. (Figure 4).
