I have tried to get this nuget package in a Raspberry Pi 4, but it always fails.
I do it using: dotnet add package Hardware.Info
I was wondering if this should work? Or if it has been tested in a Raspberry Pi device?

There are two scenarios when the network speed is displayed incorrect:
As you can see the network speed is set to long.MaxValue because the network card isn't plugged in at all, which you can see in the NetConnectionStatus is set to 7
And in this network adapter there is no speed at all which leads to a value of 0 because GetPropertyValue returns the default. But if you read the network speed from Win32_PerfFormattedData_Tcpip_NetworkAdapter the value is set correctly there, so as fallback you could read that value.
The network speed should displayed correctly and shoudl not be misleading

Is your feature request related to a problem? Please describe.
At the moment, the library appears to use some type of binary-encoded version for each of its releases. Generally, it's more useful for downstream users of the library if the release version is somewhat descriptive of the changes made to the library from the previous version to this one.
Describe the solution you'd like
Most software libraries use semantic versioning for its releases, indicating compatibility changes in the components of each version release (major is breaking, minor is new features, patch is a pure fix without any functionality changes). It would be nice if Hardware.Info also used this system.

I'm often frustrated because I need a way to calculate CPU usage, but I'm unsure of the best approach.
Describe the solution you'd like
I would like a straightforward method for obtaining the CPU usage percentage of the system, whether it's through a specific library, API, or another means.
Describe alternatives you've considered
I've considered using the System.Diagnostics.PerformanceCounter class to retrieve CPU usage, but I'm also interested in knowing if there are other, more convenient methods available.
Additional context
I'm developing a monitoring tool that requires real-time CPU usage data. I'd like to find a solution that is cross-platform as my application will run on different operating systems.
Please provide additional context or requirements if needed, so that I can better understand your request and offer more detailed assistance.
Hi sir, sorry this is not a bug, just curious about this lib even works fine with AOT mode, because System.Management is obviously not compatible with AOT mode: dotnet/runtime#61960
so what magic did you use, sir?
and thanks~
Is your feature request related to a problem? Please describe.
Is it possible to create a method to check if the user account/current account has permissions to use WMI? Or during initialization throw an exception indicating the same?
Describe the solution you'd like
A method or an exception while initializing the class indicating the user does not have permissions to use WMI
Describe alternatives you've considered
None yet.
Additional context
None.
Add more information to the Hardware.Info project, precisely add usage for each CPU core and overall CPU usage and also add network throughput for each interface.

We first tried on a Raspberry Pi 4, no info seems to be coming except in Networks, where IP and MAC address are one of the few pieces of information entered.
We then tried (With the same Debian distro) on a Asus h61m-f, there we get a little more information on the bios, but for instance RAM is not filled in.
For CPU on Raspberry Pi 4 it only collects the L caches for the CPU, that's it.
These attempts have been done as sudo.
We also tried running it on Windows and then it collects everything.
We are just testing this for now before we decide to use it or not, as such we are just collecting everything and dumping it.

Thank you for such great library! I have 3 questions with decreasing importance.
new HardwareInfo(), .RefreshAll(), and all properties be accessed from one child thread that is not main, is there is some possible caveats?HardwareInfo be used by multiple threads, is it thread safe?Is your feature request related to a problem? Please describe.
Your library isn't mockable and thus makes it difficult to unit test around.
Describe the solution you'd like
I would like an interface on the "main" HardwareInfo class that exposes the public properties and methods so that it can be mocked by a library like MOQ.
Describe alternatives you've considered
Currently, the only way to unit test methods using your library is to wrap your library in a testable interface and make your library the concrete implementation through DI. This is a less than ideal solution.
I cannot any monitor by WMI API. I've wrapped it myself and it doesn't seem to be easy to get this information. Have you ever encountered this problem?
I found it impossible to get them using the handle method. I had to use a keystroke script(such as autoit) to get the content, but it was a little less elegant.

Is there a way to get Model and Manufacturer properties of ComputerSystem ?

The CPU name along with some other properties like the clockspeed are empty.
Run the test project on an M1 Mac.
Since I happen to have one of these (an M1 Max) I will look into submitting a fix for this. I tried manually running the command to look up the CPU and it returns the string "Apple M1 Max" but it looks like the code is assuming an @ character be present. I'll have to investigate if there are other sysctl arguments. I have an old Intel Mac mini I can set up to make sure I don't break the Intel CPU info.

OS & OS version
Windows 10
Describe the bug
All results returning as expected, no errors produced, however, a couple of elements are taking excessively long to refresh.
CpuList refresh at ~30 seconds, NetworkAdapterList at ~1.1 seconds. The rest are pretty much sub 100 millisecond territory.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
Would be great if CpuList would return faster. If there is no way around the slowness, perhaps you could isolate the slow bits, and add options around whether to refresh them or not so that there is a fast-path available to users that don't require the extra data.
Additional context

Windows 10 and 11, could also be on other windows version, too. But I have only Windows 11 on my machine.
BytesSentPersec and BytesTotalPersec of a network adapter is always 0, no matter how many data are sent or received.
The problem here is that the network adapter name from "SELECT * FROM Win32_NetworkAdapter WHERE PhysicalAdapter=True AND MACAddress IS NOT NULL" is with a #. See screenshot:
But if you try to read the BytesSentPerSec and BytesTotalPersec, the network name to match has changed with a _
See screenshot:
In the class HardwareInfoRetrieval.cs:564 you are already change ( with [ and ) with ], so I think you will also need to change a # to _ if they appear in the name otherwise it won't match and the values will always be 0
BytesSentPersec and BytesTotalPersec should show the correct value

11.1.0.1
OS Name: Microsoft Windows 11 Home
OS Version: 10.0.22621 N/A Build 22621
I got three screens connected, but only one is returned when querying hardwareInfo.MonitorList
using Hardware.Info;
var hardwareInfo = new HardwareInfo(useAsteriskInWMI: true);
hardwareInfo.RefreshAll();
foreach (var hardware in hardwareInfo.MonitorList)
Console.WriteLine(hardware);Steps to reproduce the behavior:
All monitors should be shown.
I found this https://stackoverflow.com/a/36788720/1199089 stack overflow post that suggests there are two possible origins for dieplays. If I use the second origin on my machine, I get all screens connected.
First off, big thanks for this awesome lib! I'm digging into CPU metrics on Windows and wondering how to get the PercentProcessorUtility instead of PercentProcessorTime. It seems more in line with Task Manager's display. Any tips on grabbing this specific metric?
Is your feature request related to a problem? Please describe.
I have experience numerous machine where WMI is corrupted resulting in a ManagementException
WMI is also really slow, so wanting
Describe the solution you'd like
Since WMI is Windows specific anyways, wouldn't it be possible to get more or less the same values using Win32 APIs.
I imagine this being faster and not prone to corrupted WMI.
Describe alternatives you've considered
Much of the information could be retrieved through Win32 API:

Windows version (name) is available in the branding api

Only run in Windows?
11.0.0.1
Windows 11 22H2 (but the bug is on ALL versions of Windows)
VideoController.AdapterRAM is a 32 bit unsigned int and therefore limited to represent 4GB. The Windows code fills the value using WMI which unfortunately has the same bug. Any video controller with more than 4GB will be reported as having 4GB by WMI
(see https://www.google.com/search?q=wmi+adapterram+4gb)
On a windows machine with a video controller with more than 4GB dedicated memory
var info = new HardwareInfo();
info.RefreshVideoControllerList();
var ram = info.VideoControllers[0].AdapterRAM;
Actual amount of memory should be reported
Hi,
great work.
but I found PercentProcessorTime is always zero on Linux.
Is it a bug or missing feature?
thanks
I want to to get GPU usage to monitor GPU informaton, but it seems that I cannot find API here. 🤔
Thank you for many functions you provide in this package, it really helps me a lot. ❤️
Hi, i'm sorry for this issue report and it's actually not a bug nor feature request....
just i'm confused about the WMI timeout value.
if i initialize the class this way:
var hardwareInfo = new HardwareInfo(false, TimeSpan.FromSeconds(1));it will work normally even if fianlly it takes 6seconds.
but if i initialize it with TimeSpan.FromTicks(1) it will fail to create HardwareInfo instance.
(if pass null for the TimeSpan argument it will also throw exception immediately, for this case i can understand it's an invalid argument or something like that)
anyway, why 1 second works and 1 tick not?
what is the proper shortest timeout to choose?
thanks so much!
or maybe we can make the instance creating alwasy success, but fail on RefeshXXX methods?

Retrieve the Windows OS version
Describe the solution you'd like
Want to retrieve the Windows OS version.
Describe alternatives you've considered
Currently using ManagementObjectSearcher to get the OS version used
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT Caption FROM Win32_OperatingSystem"))
{
foreach (ManagementObject os in searcher.Get())
{
OSCaption = os["Caption"].ToString();
break;
}
}Additional context
I have seen methods being called to get the windows OS version here. Is it possible to expose this so we can use this in our application to detect the windows version.

RefreshAll() method throw System.Management currently is only supported for Windows desktop applications.

cpu.CurrentClockSpeed is incorrect on some processors. Those processors scale performance based on load. Under high load it is lower than the actual clock speed. Under light load it is higher than the actual clock speed. In fact it always the same as cpu.MaxClockSpeed.
Modern CPUs can scale their performance. The code for this library only uses WMI queries. WMI does not appear to account for this fact.
The correct calculation for those sorts of CPUs is to scale the maximum CPU speed returned by the current WMI query being done by the Windows Performance Counter: \Processor Information(_Total)% Processor Performance
This SO question has the correct calculation in the answer.
Example processor: 12th Gen Intel(R) Core(TM) i7-12700H
HardwareInfo.RefreshCPUList() while under heavy load.When my CPU, which is 2.3Ghz, is at 150% ProcessorPerformance I should get 3450 for cpu.CurrentClockSpeed.
cpu.CurrentClockSpeed reads 2300.
As for this: If you don't provide C# code to reproduce the problem, the issue will be closed.
Since this is hardware specific, and I've pinpointed the root cause, the correct calculation, and an StackOverflow article with code you should be able to all but copy and paste from, you should have all the information you need to proceed, for Windows. Hardware may be a different story. I don't know about Macs or Linux.
So, please make an exception. You will need to get the right hardware... or someone with it willing to run the code and report findings... I'm willing to be that guinea pig.
