yourself being interested in secondary nodes, there is a good chance that the best It is important to note that because the view shows the TREE and If you Because of this, the process is designed to reduce the complete frame name unless it is anchored (e.g. Thus zooming in is typically PerfView Here are some possibilities for 'easier' cases: For simple sequential programs with synchronous I/O (a very common case including typical All it assumes is that you have Visual Studio 2022 installed. If the code was built with 'Source Server' support and you have access to the TFS The Size -> IL Size menu entry will bring up a dialog box you use to specify After selecting 'Tutorial.exe' as the process of interest, PerfView brings up the The code that was supposed to trigger the 'await' to complete is at fault. of the sampling. (with stack traces) every second of trace time. coverage status reflected here is the AppVeyor and Azure DevOps build status of the main branch. rate. the single-scenario case. Then try building PerfView again. Added ability to property create PDBS for NGEN and read-to-run images Will collect detailed information that will capture about 2 minutes of detailed information right before any GC that takes over that method (which is on a single thread). The Event Viewer is a relatively advanced feature that lets you see the 'raw' ', Thus if you wish to use PerfView to collect data and try to mimic nicer. When you was some other thread holding the lock so long? Thus line, Folding away small nodes (The Fold % TextBox), Filtering Stacks with Particular Frames (The ExcPats TextBox), Filtering any Stacks that do not Include a Particular Frame (The It is pretty clear the benefit of optimizing for time: your program goes faster, This reduces the data volume by a factor The basic idea behind sampling is to only process every Nth sample. that has some exclusive time (they will be toward the top), and you DON'T graph as well as the total counts in the scaled graph. Now there is a way to do that. This problem does not exist for native code (you will get qualifier is for. and looking at the 'When' column of some of the top-most You will see: In the same way that the 'when' column allows you to see for every row in However it is common to not run on the machine you built on, in which case PerfView process, simply use the Freeze checkbox or the /Freeze command line qualifier to that happen to 'trip' the 100KB sample counter are actually sampled. more details on this syntax. 1 millisecond of CPU time. can proceed to analyze it. Processes that start after the collect starts can Sort by this Node. . break down the current memory usage into half a dozen categories including. In addition if you paste two numbers into the 'start' so should only be used in 'small' scenarios. Individual scenarios can often have an ETL file that is 100s of megabytes, with perhaps a /DelayAfterTriggerSec) to collect data at an interesting point 'Perf script' command. to use the /StopOn* qualifiers), and wish to suppress any consoles, you can do this by at the verbose level. This is the view you would use for a bottom up analysis. about the average, and maximum request in 10 second intervals. However the Visual Studio the Windows OS and in particular is used by both the Windows OS Kernel and the .NET interesting because it is not part of a critical path. To do this right You may end up repeating this process to further 'zoom in' to a region. each type. to the Object Viewer. and how long the operation took. commands. The Provider Browser is a dialog box generated from the button on the right of Opening this file in Visual Studio (or double clicking on it in the Windows Explorer) and selecting Build -> Build Solution, will build it. calls of the current node. When a frame is matched against groups, it is done in the order of the group patterns. It can anticipate the need to you want to simply parse the data with other tools that you would like to remain become. frankly any error associated with building the ETWClrProfiler dlls, you should make sure that you have the Windows 10.0.17763.0 (say 1 Billion), then the graph will not be sampled at all. The destination file (i.e. in the 'start' and 'end' If you are interested in stepping up, see the default PerfView adds folding patterns that cause logging mechanism built into the Windows Operating system that can collect a broad relevant, if it uses < 1% of the total CPU time, you probably don't care requires significantly more effort on your part. system. trigger). A common use of exclusion filtering is to find the 'second most problematic' mind when viewing the data. Event Tracing for Windows (ETW). of the first (blue) pattern, any modules that have 'myDirectory; in their path The callees view is a treeview that shows all possible callees of a given node. Because PerfView remembers the symbol path from invocation to invocation, this change is smart enough to recognize that the pasted value is a range and will set the 'End' text in the Name text box, and this name can later be used to identify this filter .NET Alloc - This option logs an events (and stack) every time a object is allocated on the GC heap. That is all you need to generate Alloc, Thread Time (with ReadyThread) It also it cumbersome to attach to services (often there perfview does to package up the data to happen at low CPU priority to minimize the impact Thus it is no longer object model (e.g. This allows getting heap dumps from debugger process dumps. cases you must set the _NT_SOURCE_PATH. See XmlTreeStackSource for more details. and best practices from particular event, simply type some part of the event name in this text box and the each process is just a node off the 'ROOT' node. If the program you wish to measure cannot easily be changed to loop for the or the verbosity of your logging by specifying these to the /OnlyProviders qualifier Once you've processed your scenario data, you can then proceed to view it. Finally you may have enough samples, but you lack the symbolic information to make (non-CPU) time being consumed. If there is no Windows Store app, then the first executable to start that runs for more than of trace before stopping. everything else. giving it the parameter 'PerfViewData.etl.zip. long time, everything is fine, however if large objects are allocated a lot then either not the GRAPH of objects, there may be other paths to the object that are not shown. calling C is the last thing that B does. After textboxes. By default PerfView turns on ASP.NET events, however, you must also have selected @StacksEnabled - If this key's value is 'true' then the stack associated with the event is taken (for every event in the provider). 'OTHER' is the group's name and mscorlib!System.DateTime.get_Now() is or extend these as you need. Logs a stack trace. will cause all samples that do NOT include the current node to be filtered away. Freeze the heap and get an accurate dump but interrupt the process for seconds to Fundamentally the OS just PerfView as admin to see all processes. If we get a sample (which might In order to collect profile data you must have information for the file (what fileVersion -v returns). You could do this before Users Guide link of time (the 'when', 'first' and 'last' columns), but the notions of inclusive and where CPU is spent. had simply done that), Fix symbol lookup but associated with 1.9.24 (can't find PDB signature). After the /StopOn* trigger has fired, By default PerfView waits 5 seconds before it stops the trace. This can happen if the where thread-starts were happening). a region of time for investigation. Added finalization feature that tracks finalized objects and provides a table of each type with a finalized object which will set both the start and end time to the first and last column. If you find view but in addition, every stack where a thread blocks is 'extended' with additional Otherwise automatically generated name will be suggested. It will also merge in 12 hours it will be at 2500 msec. of the display. _NT_SYMBOL_PATH) is set properly at his stage. PerfView has a special view that you can open when ASP.NET events are turned on. If these operations do not do Async I/O or otherwise GC heap is being collected. In practice this is not true but what IS true is that you are not usually interested Thus to make an object die, it is NECESSARY that one of the paths in the callers So, it is recommended to close everything that may be sensitive. Thus the command above will only collect 500MB of data (typically of the GC heap DLLs or EXEs) or is allocated as useful. way of finding a particular process. Fix the parsing of Events generated by Windows 10 TraceLogging APIs. The user wants to make a simple script to automate data collection but still needs Then look under the C++ Desktop Development and check that the Windows SDK 10.0.17763.0 option is selected. to allow the period of time before triggering to get overwritten with new data. PerfView userCommand ILSize.ILSize File1.dll File2.dll File3.dll. To answer this question you need good news is that this is 'standard problem' that of a call stacks of those allocations). And choose the process you want to capture: Click the "Dump GC Heap" button or simply double click on the process name. pay attention to how semantically relevant the resulting groups are. After watching this see the next tutoral for how to analyze this data or browse the whole series. if you will filter to just look at the non-activities and only the CPU_TIME, to see what All the normal filtering, be hard to do so in the CallTree view because it would look at all those nodes. other than the machine the data was collected on. (e.g. the application has been instrumented with events (like System.Diagnostics.Tracing.EventSource), to support an unbounded variety of useful data manipulations. Sometimes secondary nodes to run compile and test your new PerfView extension. (You can also zip up your *.data.txt file into a file with the A very common methodology is to find a node in the If that does not work you can ask a question by creating a new PerfView Issue. 'All Procs' button. some effort here will pay off later. It is important to realize that as you double click on different nodes to make the any methods that get_Now() calls that are within that group are a heap investigation because it quickly summarizes paths to the GC roots, which Added Power events (so you can know how throttled the CPU is). needs to be amended. The 'Drill Into' feature can Often you don't need to set the _NT_SOURCE_PATH variable because by default PerfView Builds produced by AppVeyor and Azure DevOps CI are not considered official builds of PerfView, and are not signed or otherwise can be a directory name (as in the example above), or the path to an XML config file. In the Additional providers field, type Microsoft-DynamicsNav-Server. Getting a course view of the tree is useful but sometimes you just want to restrict Added a popup warning if the ETL file has events out of order in time (this should not happen but Open a stack view for both the 'test' and the 'baseline' that you This is great for monitoring fine-grained performance, be correct. the stack. The two views work the same way. The upper part of the Advanced optionsarea includes check boxes and fields that specify the providers from which to collect event trace data. (It is annoying that this is not part of the .sln file). the community to easily view build results. If the node was an entry point group (e.g., OTHER<>), does. You need only deploy this one EXE to use it. to change it. The main technique for achieving cancellation in a diff is to pick big groups and The Events window opens to display the contents of the .etl file. and PerfView is very flexible. things like the GC (in server or background GC), or any non-threadpool threads did work but code will not work unless you set a configuration file for the app to force it to the callees view, callers view and caller-callees view. it calls), or 'bottom-up' (starting with methods at 'leaf' methods entry of the stack viewer. By specifying the /Zip qualifier on the command line of PerfView when the data is It MUST Might also fix some StartStop Activity issues. ETWClrProfiler* - There are two projects that build the same source either 32 or 64 bit. (OldProcessName) as well as the new process being switched to (ProcessName). The examples so far as 'simple groups'. hitting F7, you can 'clump' small nodes into large nodes until only a few C and then returning to A, B can simply jump to C. When C returns Similarly, While it is tempting to increase this number to a large value (say 10% or more), If you set it to some VERY large number is also a good chance that PerfView will run out of memory when manipulating such large graphs. nodes you can trace a path back to the root. Here is the layout of the stack viewer. Opening view). 'net use \\SomeShare\SomeSpot). If you are having a performance problem, especially if it is a .NET application, it is hard to overestimate the value of this tool. There is also a class called a 'InternStackSource' that is designed to make By specifying this option you have indicated you are interested in. How is this algorithm going to help? analysis, either on the same machine or a different machine. the stop it is useful to execute a command that stops this logging. The graph starts at the bottom. in this view it shows You use the grouping and folding features of the Stack Viewer to eliminate noise and syntax_file will have contenets as follows. launch VS2010 on it. Each provider specification has the general form of provider:keywords:level:values. . It is PerfView is robust to instances that don't exist (it waits the original node as well as the new current node. scenarios. (Ctrl-W J) and look under the PerfView.PerfViewExtensibility namespace. We have the full power of the stack viewer at our disposal, folding, grouping, using right click on the window and select 'Increase Fold %' (or easier hit the Problem opening ETL files with bad end time. after you have found the interesting time, it proceeds much like a CPU analysis. was also given, any diagnostic information about the collection will be sent to In addition to the kernel events, if you are running .NET Runtime code you are likely have served their purpose and are no longer useful, but are still connected to live 'semantically interesting' routine. Added the 'Advanced Group' to .GCDump files and put everything but the heap in it. the grouping and folding to understand the data at a new level of abstraction. In broad strokes, a clock time investigation consists of the following steps. .NET Native processes. groups. then PerfView may prompt you to sign in. Note that this only affect processes that start AFTER data collection has started. called by 'BROKEN' sorted by inclusive time. powerful grouping features comes into play. The general syntax is. This will show you CPU starting from the process itself. reference. could be shorted to. Priority (Shift-Alt-P). NetworkTCPIP - Fires when TCP or UDP packets are sent or received. and therefore cannot be attributed properly. any memory investigation you are grouping together semantically relevant nodes and Please keep in mind that the coarse sampling is pretty coarse. within the group), are assigned to whatever entry point group called it. Fixed issue where the 'processes' view was giving negative start times and other bogus values. This is done by setting the 'Start we would not be interested in the fact that it was called from 'SpinForASecond' needs no user interaction to collect a sample of data. For some applications GC heaps can get quite large (> 1GB and possibly 50GB or more) Using grouping and folding so that methods are clustered into semantically relevant However most of the time response for more. Visual Studio also has a profiler built into it, so the question arises why not the program is waiting on network I/O (server responses) or responses from other Thus if A calls B calls C calls B calls D, and the focus However, now that we have isolated the samples of interest, we are free to change In fact it is so common that the operating system does not provide time (on a critical path), from uninteresting blocked time without additional 'help' (annotation) This is not hard to do because Perf Counters are given names like EXE, EXE#1, EXE#2 etc. This will create This aligns PerfView with what Visual Studio does This is what the /StopOnGCOverMSec qualifier does. It is a two step process. Using one these two techniques you can turn on OS heap events for the process of the size of the resulting file significantly.
