I am working on asp.net core webapp hosted on azure and I want to write my Elmah logs to my azure table storage .Many of the examples I looked into are using "API_KEY" and "logbucketId" but I am not sure what they are.
For instance as per elmah docs here https://docs.elmah.io/logging-to-elmah-io-from-aspnet-core/
app.UseElmahIo(
"API_KEY",
new Guid("LOG_ID"),
After installing nuget package, I don't see any API_KEY or LogBucketId in my appsettings.json file.
Where I can find my API_KEY and LogBucket_Id ?
https://github.com/ElmahCore/ElmahCore supports .net core now.
It is not based on Modules or Handlers, but Middleware.
It works fine although still limited.
The async calls are not being used at the moment. But it is quite extensible.
ELMAH doesn't work with ASP.NET Core, since ASP.NET Core doesn't work with HttpModules and HttpHandlers (ELMAH stands for Error Logging Modules And Handlers). ASP.NET Core does include a new (pre-release) diagnostic tool called ELM (Error Logging Middleware - creative, right?). You can find its source and samples here:
https://github.com/aspnet/Diagnostics/tree/release/1.1/src/Microsoft.AspNetCore.Diagnostics.Elm
Another option similar to ELMAH (and ELM) but with more capabilities is Glimpse:
http://getglimpse.com/
I realize neither of these directly answers your question but hopefully you'll find one or both of these alternative tools useful.
You can check ELMAH port to Net.Core version
https://github.com/ElmahCore/ElmahCore
Make sure it is matching your expectation before you use it.
Note: This new extension is in development and doesn't support all Elmah features.
ELMAH doesn't support ASP.NET Core. The documentation you are linking to is from elmah.io. While they have similar names and elmah.io uses ELMAH for some of its integrations, they don't share code or documentation.

I've recently switched jobs from a AWS shop to an Azure shop, both using dotnet. AWS publishes Amazon.Lambda.AspNetCoreServer, which is a magic Nuget package that allows you to write a plain ol' ASP.NET core Web API and deploy it as into a lambda with only a few lines on config. I really loved this pattern because it allows developers to just write a normal web api without having the host runtime leak into their coding.
Does anything like this exist in Azure? Even something that is community supported? Or is there some any way to achieve something like this in Azure Functions?
Unfortunately there is no simple way to do that since Azure function format is a bit different.
[FunctionName(nameof(GetAll))]
public IActionResult GetAll([HttpTrigger("get", Route = "entity")]HttpRequest request)
Then it will generate json with meta data for AF.
If you wish to host pure .net core without any changes I would look into Containers option
PS0: Theoretically it would be possible to do it with little bit of reflection. For instance you create project with all your Asp.Net core apis, which you can use in asp.net core hosting. Then you write tool which grabs your dll and using reflection you find all actions in your controllers and generate code for AF
PS1: Have a look https://github.com/tntwist/NL.Serverless.AspNetCore
TL;DR: Does ExcludedTypes in Microsoft.ApplicationInsights.AspNetCore SDK default to Exception and Trace?
I am running an ASP.NET Core 2.2 app with version 2.6.1 Microsoft.ApplicationInsights.AspNetCore SDK. I am reading: https://learn.microsoft.com/en-us/azure/azure-monitor/app/sampling#configuring-adaptive-sampling-for-aspnet-applications where they write that the default values for ExcludedTypes is Trace and Exception, which is just the way i like it, but I am wondering, since the default values is for ASP.NET (actually specified in the application insights config for the host), if these default values also apply for ASP.NET Core applications that doesnt have an application insights config file (all config is done through code).
I know that the SDK is open sourced, but I haven't been able to search through it and find the initial values: https://github.com/microsoft/ApplicationInsights-aspnetcore. Maybe I am just searching for the wrong things.
Update:
Yes, the default ExcludedTypes for asp.net core is Event. There'are 2 places mentionded that:
1.In this article, it says "In ASP.NET Core, exact same default behavior is enabled in code.":
2.In the source code, you can find it's defined here:
First, the default values for ExcludedTypes is not Trace and Exception, it is Event. There is a GitHub issue for that. And I also tested it myself, the default ExcludedType is Event indeed.
For asp.net core, the default ExcludedType should be same as asp.net, you can take a look at this section of the article you provided. I'll try to go through the code to find out what's in the code for asp.net core and will update you later.
looking for some advice here on developing a common logging environment for a NuGet package.
I've currently got a private NuGet package created from a C# library that works perfectly for local console apps and as such was written to log to the Windows event log.
Now I want to be able to use that package in an Azure function but of course Azure uses a different logging mechanism.
Any advice on how to create a logging overlay that allows the library to be compiled on my local PC in Visual Studio but also support logging in Azure if the package is used there?
Cheers,
Dave
I believe you are looking for the Microsoft.Extensions.Logging namespace and interface. This interface is used extensively across azure services, .Net 4+ and .Net Core. If you look for related nuget packages you will find multiple implementations for different logging scenarios and tools, including native sinks like event logs, functions, console as well as custom sinks like Splunk and Serilog.
If you separate your logging implementation from your application/package code and implement Microsoft.Extensions.Logging and adhere to the interface, then your logging interface can be easily plumbed in to many supported sinks, including functions.
A previous answer of mine provides an earlier, more manual approach to this problem. See here.
I'm trying to wrap my head around how we're supposed to build Azure functions.
I love the idea of building serverless, compact, single-function apps that respond to events.
Here are the problems I'm running into:
I have nice class libraries built in .NET Standard 2 that handle all my "backend needs" namely handling CRUD ops with Cosmos Db, Azure Table Storage, Azure SQL, Redis, Azure Storage. No matter what I did, I couldn't integrate these class libraries into an Azure Functions project. More details below.
Also, getting dependency injection in Azure Functions project has proven to be quite a task -- especially with my class libraries mentioned above.
At this point, the only option I'm seeing is to "copy and paste" code into a new Azure Functions project and use it without any DI.
This seems to go against "best practices". So what's the solution other than either to create monolithic code or wait till Azure Functions support .NET Core and DI.
I thought I could use my .NET Standard class libraries from a regular Azure Functions project targeting .NET Framework. After all, the idea of .NET Standard is to "standardize" things. I opened a couple of posts here on SO. I'm providing the links so that you can see the issues I've run into:
Using .NET Core 2.0 Libraries in WebJob Targeting .NET Framework 4.7
No parameterless constructor error in WebJobs with .NET Core and Ninject
P.S. My previous posts are referring to WebJobs. That was plan B approach because WebJobs seem half a step ahead of Azure Functions when it comes to supporting things like .NET Core and DI. Ultimately, I'd like to build a few Azure Functions that can use my class libraries built in .NET Standard 2.
Also, my previous posts mention that my class libraries target .NET Core 2.0. Since then I converted them to .NET Standard 2 which didn't really take much at all. I did this so that I truly conform to .NET Standard 2.
One issue is that Visual Studio has an outdated version of the Functions Core tools. Until this is resolved, you can work around in the following way:
Install the latest via npm by running npm install -g azure-functions-core-tools
In your Function App in VS, go to the Properties
Go to Debug, and click New... under Profile
Name the new Profile something like FunctionsNpm
Set the executable to (replace [YourUserName]): C:\Users\[YourUserName]\AppData\Roaming\npm\node_modules\azure-functions-core-tools\bin\func.exe
Set the arguments to host start
Set the working directory to $(TargetDir)
In toolbar, look for the green triangle icon to change your current Profile to the one you just created:
Now when you run from VS, you'll be using the npm tools instead of the older one that come with the VS package.
.NET Standard 2 support is on its way, see this github issue.
Is there any up-to-date guide that will help with integration of Elmah into ServiceStack for logging? Anything I look, like this question is out of date since methods changed.
Ideally I would like to receive error emails like described on this link, but for start I would just love to be able to go to elmah.axd and see all unhandled errors.
I've already installed Elmah and configured web.config (which I've done using NuGet). Now I'm stuck as to what to do after doing Install-Package ServiceStack.Logging.Elmah - most of old tutorials say that I need to use NLog (which I don't want to do - since I don't want multiple logging components).
Thanks for the help!
This post should cover it: http://blog.elmah.io/logging-to-elmah-io-from-servicestack/
The post explains how to integrate with the elmah.io logger, but the method is the same for other types of ErrorLog implementations for ELMAH. Instead of installing the elmah.io NuGet package, you can install the ELMAH package, which gives you a default set of configuration in your web.config using the memory error log.
