Tracking CPU and Memory usage per process

Question

I suspect that one of my applications eats more CPU cycles than I want it to  The problem is - it happens in bursts  and just looking at the task manager doesn t help me as it shows immediate usage only   Is there a way  on Windows  to track the history of CPU  amp  Memory usage for some process  E g  I will start tracking  firefox   and after an hour or so will see a graph of its CPU  amp  memory usage during that hour   I m looking for either a ready-made tool or a programmatic way to achieve this

Just type perfmon into Start  gt  Run and press enter  When the Performance window is open  click on the   sign to add new counters to the graph  The counters are different aspects of how your PC works and are grouped by similarity into groups called  Performance Object    For your questions  you can choose the  Process    Memory  and  Processor  performance objects  You then can see these counters in real time  You can also specify the utility to save the performance data for your inspection later  To do this  select  Performance Logs and Alerts  in the left-hand panel   It s right under the System Monitor console which provides us with the above mentioned counters  If it is not there  click  File     Add remove snap-in   click Add and select  Performance Logs and Alerts  in the list    From the  Performance Logs and Alerts   create a new monitoring configuration under  Counter Logs   Then you can add the counters  specify the sampling rate  the log format  binary or plain text  and log location

Under Windows 10  the Task Manager can show you cumulative CPU hours   Just head to the  App history  tab and  Delete usage history    Now leave things running for an hour or two     What this does NOT do is break down usage in browsers by tab   Quite often inactive tabs will do a tremendous amount of work  with each open tab using energy and slowing your PC

Although I have not tried this out  ProcDump seems like a better solution   Description from site      ProcDump is a command-line utility whose primary purpose is monitoring an application for CPU spikes and generating crash dumps during a spike that an administrator or developer can use to determine the cause of the spike  ProcDump also includes hung window monitoring  using the same definition of a window hang that Windows and Task Manager use   unhandled exception monitoring and can generate dumps based on the values of system performance counters  It also can serve as a general process dump utility that you can embed in other scripts

You can also try using a C  Perl Java script get the utilization data using WMI Commands  and below is the steps for it   We need to execute 2 WMI Select Queries and apply CPU  utilization formula  1  To retrieve the total number of logical process   select NumberOfLogicalProcessors from Win32 ComputerSystem   2  To retrieve the values of PercentProcessorTime  TimeStamp Sys100NS   CPU utilization formula has be applied get the actual utilization percentage and WorkingSetPrivate   RAM   minimum of 2 times with a sleep interval of 1 second  select   from Win32 PerfRawData PerfProc Process where IDProcess 1234   3  Apply CPU  utilization formula  CPU     p2-p1   t2-t1  100  NumberOfLogicalProcessors   p2 indicated PercentProcessorTime retrieved for the second time  and p1 indicateds the PercentProcessorTime retrieved for the first time  t2 and t1 is for TimeStamp Sys100NS   A sample Perl code for this can be found in the link http   www craftedforeveryone com cpu-and-ram-utilization-of-an-application-using-perl-via-wmi   This logic applies for all programming language which supports WMI queries

Process Lasso is designed more for process automation and priority class optimization  not graphs  That said  it does offer per-process CPU utilization history  drawn as a white line on the graph  but it does NOT offer per-process memory utilization history    DISCLAIMER  I am the author of Process Lasso  but am not actually endorsing it here - as there are better solutions  perfmon being the best    The best thing ever is Windows Vista  Resource and Performance Monitor  It can track usage of CPU  Memory  Network  and Disk accesses by processes over time  It is a great overall system information utility that should have been created long ago  Unless I am mistaken  it can track per-process CPU and memory utilization over time  amongst the other things listed
