Lean how Resource Monitor is an extension of Task Manager and what it offers over the latter. Explore ways to open Resource Monitor. Use each tab, Overview, CPU, Memory, Disk, and Network to review system statistics such as current disk I/O rate and Current hard faults per second. Use the information to improve system performance.
- Resource monitor offers real time insight into your computer system. This is a good troubleshooting option when you don't find the answers you are looking for in Task Manager. In fact, there's a link to Resource Monitor from inside Task Manager just for that purpose. Like other system tools, there are multiple ways to open Resource Monitor. I like the key combination Control + Shift + Escape but you can also use any of the options here. Control Shift Escape opens Task Manager.
I'll click the Performance tab and clock open Resource Monitor from the bottom left corner. Let's let this run and observe what happens to the graphs on the right side. This is real time data, just like you see in Task Manager, but with more detail. I'll drag this side out to show a longer time span. You'll need to have some knowledge of threads, processes and the inner workings of the computer to use what's offered here. From the Overview tab you can select specific applications from the list to filter what you see in the other sections below.
I'll expand Network right now and let's take a look at all of the entries. Now I'll only select a few items to show. I'll clock Image to sort them alphabetically and I'll click everything that has to do with Chrome. I'll perform a couple of searches using Chrome now and show you what happens in the Network window. Back in the Network window you can see a list of IP addresses and some information on the right side about the bytes sent and received.
Now let's look down a little further and extend Memory. If you're familiar with the terms showing in the headings, you can likely make some sense of the results. You might see that there are hard faults for instance. A hard fault occurs when Windows has to temporarily store data in the swap file on the hard disk instead of RAM. This happens when RAM is full. When data is stored in the swap file, it takes longer to load or retrieve and can cause noticeable performance problems. If you see a lot of hard faults and can attribute them to a single program, you may be on to something if you're troubleshooting.
To see each computer component individually, click the respective tabs. Since we've already talked about Memory, let's click the Memory tab to continue the conversation. Chrome is the only item selected, so what you see in the results only applies to that program. Look to the right and you can see used physical memory, commit charge and hard faults per second. It's a nice graphical representation of what we saw on the previous screen. Click Network now to see what applications are using network resources.
Again, you can select or deselect to narrow the results. If you want to see, say, the impact on the network from a single application, like OneDrive, you can get that information here. You can save the settings you've configured for another time if you'd like. The option to save is available from the File tab. When saved you can load the settings whenever you want to use them again. Although I don't use Resource Monitor very much, I do look around in here if I feel a specific program is causing my computer to bog down.
Even without knowing too much about it, you can use Resource Monitor to filter down to one application and see easily what effect it's having on the CPU, the disk, network and memory and that might be all you need to resolve hard to diagnose problems with your PC.
