etw

问题 I would like to know what are yours experiences regarding using EventSource for components that are common and that can be utilized few times within the same process. One simple example. My shared component is TestQueue and I would like to utilize it few times with my process and again in PerfView to see what event belongs to which queue. public class TestQueue<T> { private readonly IEtwQueue _etwQueue; private readonly Queue<T> _instance = new Queue<T>(); public TestQueue(IEtwQueue etwQueue)

问题 I am trying to use the ETW functions without success to read the file: C:\Windows\System32\winevt\Logs\Microsoft-Windows-Diagnostics-Performance%4Operational.evtx In order to capture boot time events. I have tried various functions - OpenTrace gives an error 161 EvtQuery gives an error 15000 Does anyone have a native code example of reading system trace files? 回答1: I got this working as follows - LPWSTR pwsPath = L"Microsoft-Windows-Diagnostics-Performance/Operational"; LPWSTR pwsQuery = L

问题 I am capturing ADO.Net diagnostics ETW, as described in Data Access Tracing in SQL Server 2008. The setup works, an ETL file is produced and I can see the ADO.Net trace if I use, say, tracerpt: System.Data, TextA, 0, 0, 0, 0, 17, 0, 0x0000000000000000, 0x000007D0, 0x00003A64, 1, , , {00000000-0000-0000-0000-000000000000}, , 131485096603462277, 450, 2400, 2, "enter_01 <prov.DbConnectionHelper.CreateDbCommand|API> 1# " System.Data, TextA, 0, 0, 0, 0, 17, 0, 0x0000000000000000, 0x000007D0,

问题 I have been working on using .NET4.5 new feature ETW(EventSource). I have trouble having it show up on the trace provider lists using perfmon->Data Collector Sets. I was able to see the logs using perfview. I was able to generate manifest from EventSource class using its static method GenerateManifest. This will provide the manifest of myevents in EventSource class but it does not contain details about the channels. My question is how to add channel specific information after generating the

问题 I'm researching Event Tracing for Windows (ETW) to allow a user-mode windows client to write out tracing information. The existing documentation is, to put it lightly, insanely incomplete. What would really help is a simple C++ example that writes out tracing messages using ETW. Does such an example exist? Is there other ETW documentation you might recommend? 回答1: To write a Provider for ETW, you have two options: write it as a manifest-based provider (preferred for Vista or higher). Check

问题 An answer to this question has led me to look into using "Event Tracing for Windows" for our tracing needs. I have come across NTrace, which seems to be a good way to produce ETW events from C# code (using the XP-compatible "classic provider" model). However, I am unable to find an easy way to consume these events - to see them in real-time and/or log them to a file. The only way I have found is that described in the NTrace documentation: using a tool which is only available as part of the

问题 I'm working on setting up a WCF service, hosted in a Windows Service, that uses Event Tracing for Windows (ETW) for logging. Currently I'm just focusing on setting up a dummy Windows Service with ETW and I'm seeing some unintended events being logged. In particularly, whenever I start or stop the service I am seeing an event with Opcode 254 and no message. I've tried looking around online but so far I haven't found any references to what this is. If you'd like to try it out, here is the

问题 I need the to write a log message and capture that in PerfView. I would like to avoid using EventLog or EventSource because they are quite invasive: they require registering a new source or ETW provider, which leaves leftovers in the system. Ideally I just want to call Debug.WriteLine (which uses OutputDebugString), but it seems that PerfView cannot collect it. Or is there some ETW provider that sees debug messages? If you have an answer, please state the two parts of the solution: What

问题 I've been trying to work with ETW in .net 4.0. I have started using Microsoft EventSource Library 1.0.4-beta (https://www.nuget.org/packages/Microsoft.Diagnostics.Tracing.EventSource) Here is the code i written for generating events for my application. [EventSource(Name = "Samples-EventSourceDemos-EventSourceLogger")] public sealed class EventSourceLogger : EventSource { public static EventSourceLogger Log = new EventSourceLogger(); public static string GetManifest() { return GenerateManifest

问题 WebUI for Windows IoT (as seen on Raspberry PI) features the following Event Tracing screen: How do I write into an event log from a uwp program and then later examine what's written there? This answer (which is not about Windows IoT) suggests that you need to use standard System.Diagnostics.Tracing classes for it. The sample that this answer is referring to is to demonstrate logging to a file . I'm more after logging to a built-in facility, such as ETW. Following similar logic as in the
