CPU-, Memory- and Disk-Usage

[mueer01]

Hello,

is there any function in WinBatch, to get the total CPU-, Memory- and Disk-Usage ?
(Those values, that can be seen in the TaskManager.)

Regards,
Erhard

Haven't tried it but you could download the Nuget package system.diagnostics.performancecounter.7.0.0.nupkg here:

https://www.nuget.org/packages/System.Diagnostics.PerformanceCounter/

Nuget packages are glorified Zip files so you can unzip the contents with most zip file utility programs. The .net assembly (.dll) you want is in the system.diagnostics.performancecounter.7.0.0\lib\net462 folder. You can look at examples of .Net programming in WIL in the Tech Database if you are not familiar with it. You can likely find some c# examples of using the assembly with a Web search. With some limitations and restrictions, C# examples can often be translated to WIl.

But as previously mentioned I have not tried it so I don't know if the assembly will work with WinBatch.

Might take multiple queries, but maybe WMI would provide that.

Might be possible for at least some metrics. Here's a link to some WMI script examples. At least one of these might work to obtain CPU usage per process on an ongoing basis.

Yep. When in doubt check out the Tech Database. I guess the purpose behind the Op's ask may be worthwhile pursuing. Are we talking about a static dip for specific metrics for a specific PID, for a PID's or a rolling/polling script, possibly as a WB Service.

The OP uses the term "Total" but it is unclear if per process, per logical core, or system processor is the intended target.

MSFT's site has a page that discusses using WMI to collect performance data here:

https://learn.microsoft.com/en-us/windows/win32/wmisdk/monitoring-performance-data

Here is a quick and dirty mash-up of the MSFT and Tech Database articles. Be forewarned; It can occasionally produce unusual percentages.

Code: Winbatch

strComputer = "."
objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" : strComputer : "\root\cimv2")
objRefresher = CreateObject("WbemScripting.Swbemrefresher")
objProcessor = objRefresher.AddEnum(objWMIService, "Win32_PerfRawData_PerfOS_Processor").ObjectSet

WindowOnTop( "", 1 )
BoxOpen("Performance data (refreshed every 3+ seconds)", "Initiating Process...")
Decimals(2)
Percent = ""
Stamp = ""
bFirst = 1
While @TRUE
    objRefresher.Refresh
        ForEach RefreshItem In objRefresher
            ForEach perf_instance2 In RefreshItem.ObjectSet
               if  StriCmp( perf_instance2.Name, "_Total") == 0       ;;
                  ;; Using sampling intervals prevent representational errors
                  ;; when performing floating point division on very large
                  ;; 64-bit integers.
                  if bFirst
                     Percent1 =  perf_instance2.PercentProcessorTime
                     Stamp1 =  perf_instance2.TimeStamp_Sys100NS
                     bFirst = 0
                  else
                     Percent2 = perf_instance2.PercentProcessorTime
                     Stamp2 = perf_instance2.TimeStamp_Sys100NS
                     
                     ; CounterType - PERF_100NSEC_TIMER_INV
                     ; Formula - (1- ((N2 - N1) / (D2 - D1))) x 100
                     PercentProcessorTime = (1 - ((Percent2 - Percent1)/((Stamp2-Stamp1)*1.0)))*100.0
                     BoxText("Press Escape Key to Cancel Processing":@crlf:@crlf:" Percent Total Process Time ":PercentProcessorTime:"%%")
                     Percent1 = Percent2
                     Stamp1 = Stamp2
                  endIf              
               endif
           Next
        Next
    if WaitForKeyEx("{ESCAPE}", 3) then break
 EndWhile
