I wanner develop an add-in likes perf_xxx.dll. These modules are COM components, I don`t konw which interfaces I have to implement. Is there any documents for developing Windows Performance Analyzer Add-In?

File I/O DirNotify Event Type
Hey Community! I'm looking at WPA traces to investigate specific problem for quite a while now.
Looking at the File I/O metrics, I see that quite a high amount of time is spent in "DirNotify" events with SubType "Info Class 351". However, I have no idea what those events are and what the different SubTypes (apart from "Info
Class" there's also "FileAlternateNameInformation") mean. All I see is that they take a notable amount of time and the associated process is one that I suspect is causing the perf issues we're investigating.
Does someone know what those events are and maybe has a pointer to documentation that I didn't find? What Windows API calls might those events originate from?
Thank you!

Show interrupt affinity for given driver.
Hello,
i am interested in finding out, whether DPC from driver USBXHCI.SYS are handled on a single core at the time, or on multiple cores. I am new to WPT, i am not sure where i can see this. I read, that this interrupt affinity policy -"IrqPolicyAllProcessorsInMachine" cause driver to be handled on single core at the time, which has lowest priority aka core with least interrupts being processed on it at the time. But on Microsoft docs i read, that this policy will assign interrupts to all cores in machine. So i don't know what is true and what not. I read it is not good idea to assign interrupts to all cpu cores, as it can cause cache miss. But i have good results using this policy so far.
So how is it ? Thanks!
EDIT: i think i found it, please correct me if i am wrong. I opened performance analyzer and than Computation\"DPC/ISR Duration by Module, Function *" selected my driver USBXHCI.sys. Clicked cog wheel on top of the graph, selected CPU and from the drop down menu - max. Than i checked any point on the graph and there is everywhere under Selection\Max of CPU either 0 or 1. I found some page concerning View Editor, but there is not enough documentation, i was unable to find exactly if this is related to CPU setting. But i read it is sorted by 0 based index, that would mean 1 means 2 cores. 1 is showing when i switch out of start to end selection and select a single interrupt, at least i think it is single interrupt, that is when i point cursor anywhere on the graph. And it says 0 and sometimes 1. Also it doesn't make sense when interrupt occur, that 0 cores would be handling it. Except if interrupt was in queue waiting for other interrupts to finish. I have no idea.
I could just assign single CPU core for USBXHCI.sys to handle interrupts, but i read this policy selects automatically core with least load. Correct me if i am wrong please. Again i am talking about this policy:IrqPolicyAllProcessorsInMachine.

Symbol paths not visible in Configure Symbols dialog (paths are set with check marks and symbols do load)
When I open the Configure Symbols dialog box and set the symbol paths the path names are not visible. I can set the path and the path is defined as the dialog will open again with the check marks. Symbols do load too. I can't read what the path is.
I tried this on two machines with my current build setup for the HoloLens2. Windows Pro 10.0.18363 Build 18363 Using the same SDK on Unity 2019.2.21
To be sure I have a test machine that is not a dev machine. For fun I re formatted my test machine and reinstalled windows with the latest update assistant May 2020.
The only thing I installed was the Windows Performance Toolkit from here:
https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install
I used this profile to capture my ETL file from the HoloLens 2.
Unity+CPU+MF+DotNet+DXGI.wprp
You guess it and I still get invisible paths. Two dev machines and a clean install machine too.
I have an image of the problem but I am getting the forum error about link submission and my account needing verified. I will post that image later when I can.
Anyone have any ideas?

Windows Performance Analyzer isn't a suggested application when opening ETL files
It's great that WPA is available in the store now. However, it is not a suggested application to open .ETL files with.
I.e. if you try and open an ETL file for the first time on a fresh install, the 'Open With' dialog pop-up but only tells you to search the store. I thought if it was a registered application in the store, it should still be suggested (even if not installed)?
Or is this a store issue?

CREDIT CARD REMOVAL PROBLEM
I want to remove a cancelled credit card from my payment options of my Microsoft account but I am not allowed to do it. MS says it is associated with Azzure, and this is wrong! I don´t even know what Azzure is used for. I chose just some forum randomly.
Can you help with me with that?. See the attached screen shot:

Hi Team,
I am using the virtual machine instance in VMSS. I am doing performance testing on the VMSS for one of the api. So i was trying to observe used CPU & Used RAM through the insights monitor but the monitor showing me no logs & graph or it is showing me blank.
Please refer below screen shot.
Note : I need to observe performance of the VMss Instance through azure monitor portal

Microsoft-Windows-COMRuntime: Translate COM Method ID into Method Name
I am using the Microsoft-Windows-COMRuntime provider to trace COM calls. This gives me information about the duration of a COM call, but also the target interface (Field 7) and target MethodID (Field 6).
I can find the GUID from the interface in the registry, but how do I translate the Method ID into a Method Name?

WPT folder with active cache files after running xbootmgr -trace boot
I have a folder "C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit" in Windows10 Home x64 1909 build 18363.1082 and after I ran the command "xbootmgr -trace boot -prepSystem -verboseReadyBoot" that folder contains now 7 large cab and 7 etl protected windows system files mixed with many other WPT system files (dll). When I cleaned up this mess my system crashed so the etl files are actively linked to my windows prefetch folder and never be touched. After I restored the etl files (recycle bin) my system booted up OK again. Question: Why are active system database files (etl) mixed with WPTK program files and not stored separately in the Windows Prefetch folder, are these cab and etl files in the WPTK folder properly maintained (refreshed after a new run with xbootmgr) or will it grow to a large folder with big redundant files? Is there an app available to manage the WPTK database?

Performance issues with inserting records into a table used by indexed views?
I have a fairly big table, let's call that 2B records split evenly between 200 partitions (SQL Server 2012). Every day, I have a process that takes 6 hours to create a new partition and insert 10 million rows in it.
I'm having some performance when i try to join a partition to a summarized view of that partition (10M vs 100 records). I think that if i used a indexed views instead of a sub query, i could improve the performance of my reporting, but I'm a little concerned if there are any performance issues with the inserts.
It takes about 30secs to calculate the summarized view, it will be cost (time) prohibitive if summaries view get update after every insert (x10M)
So, i will like to know if asummarized indexed view get refresh: after every insert, or the next
time a user read from the indexed view?
Thanks in advance

How to display full etl log
Hi,
I'm new in using the WPT, I logged some performance values over the weekend, starting on 2020-10-23 until today.
In system configuration, the correct start and end time is displayed:
Start Time (Local) 2020.10.23 16:29:59.5291161
End Time (Local) 2020.10.26 09:51:36.8674716
But in the graph, I always see a range from 238,764.030s...238,897.925s and I could find no solution to display the complete log from 0 till end.
Whats wrong there?
