I am new to Azure and Functions, so please bear with me.
I have a timer trigger isolated .Net 5 function. It does some CRUD operations against SQL database. It works fine locally when tested in Visual Studio 2019. However, when it is deployed into Azure, the trigger isn't invoked. It has Serilog for logging and I see no logging added to the files.
Using postman, I make a post request to the function. I can see the request count in the graph but nothing more than that.
Where can I see errors without turning on the application insights?
Thanks.

Finally i concluded ,that You can use Kudu console to see your logs for your application.
To get kudu console go to APP service>Advanced Tools >Go
After click on go it will redirect to Kudu homepage like this
From here you can choose debug console (cmd) to download and see your logs
For more information please refer this MS Q&A discussion Azure Function Time Trigger not Firing .

I built a python function in Azure. I used the library logging to record some important steps in my function. I am using the level "info" of this library. My question is how do I find the logs created after execution in Azure portal?. I would like to see these logs to validate the execution of my function.
Tks in advance
Update 1:
I found in the Microsoft documentation:
Logging Access to the Azure Functions runtime logger is available via
a root logging handler in your function app. This logger is tied to
Application Insights and allows you to flag warnings and errors that
occur during the function execution.
Python developer reference: Logging
However, I do not know how to find these logs in Applications Insights.
Update 2:
My function has already the settings:
APPINSIGHTS_INSTRUMENTATIONKEY
APPLICATIONINSIGHTS_CONNECTION_STRING
When I checked 'Transaction search' in the application insights, I am not getting the logs that I defined in my function using the library 'logging'. Here an example what I see:
The logs are seemly the standard one that Azure has.
Few things -
Have you enabled Application Insights? And setup the the storage account for logs?
Can you see Application Insights related configs in your Configuration > Application Settings
If the above are all fine, without your code snippet its hard to tell if there's something wrong.
To see the logs, try navigating to -
Your Azure Function's Application Insights
Click on 'View Application Insights data'
Then on the left nav bar look for 'Transaction Search' and click it
Finally, click the center button 'See all data in the last 24 hours'
Wait for it to load your logs, and hopefully if everything is setup correctly you'll see your logs there.
I set up Application Insights on my asp.net core (2.2) app. I can see data in Azure portal when I run my application locally. However, once I deploy it to App Service in Azure, Application Insights stop working - there is no data flow at all. Are there any additional steps I am missing?
Adding to Stuart's comments- > If you edited ApplicationInsights.config, kindly check the configuration of TelemetryInitializers and TelemetryProcessors. An incorrectly-named type or parameter can cause the SDK to send no data.
Also, in the Application Insights portal, open Diagnostic Search. Data usually appears here first. Refresh to see if it helps.
If feasible, you may restart the app and check to see if that helps.
I am in search for a good way to log various messages while being able to use functions, logic, monitoring, etc to get notified or run a certain task to fix a problem and notify someone.
What I have in mind is something like "If a specific error happens send me a notification or restart a service"
What I currently already have is an app service that holds 10 web jobs(continuous, triggered). Two of them use the Azure Web job SDK and the rest of them are plain .net core console apps. All of them generate structured logs using serilog and are saved to blob storage.
Is there something I am missing? I don't want to reinvent the wheel here.
You can use application insights with webjobs, more details are here.
You can also set an alert in application insights if error occurs, refer to this doc.
Any more questions please let me know.
I have a Node application (Bot Framework bot) hosted on Azure. What's the best way to log information for debugging? For example, as far as i'm aware, using console.log() isn't helpful because there is no console to look at in Azure. I also do not want to call tons of session.send() to the client.
So whats the best way to get some sort of debug logging?
You can leverage the Diagnostic Log extension on Azure Web Apps. Login your web app in Azure portal(https://ms.portal.azure.com/). Click on Diagnostic logs in settings option and Turn On Application logging in Diagnostic Logs Tab.
And then you can login the Kudu console site of your web app(https://<Your_Webapp_name>.scm.azurewebsites.net/DebugConsole) and browse to your Application folder(D:\home\LogFiles\Application folder).
Otherwise, you can click the Diagnostic dump on the top nav bar of the kudu console site to download the log files.
On the other hand, you can use the Log stream tool on the Azure portal(https://ms.portal.azure.com/) for a real time debugging online.
At last, you can integrate a 3rd part node.js log modules, such like winston into your application. And catch the logs into your own log file.
Any further concern, please feel free to let me know.

What I have:
VS2015U2
ASP.NET 5 MVC 6 website
Deployed to Azure Web App
The site works locally
When I deploy to Azure I get internal server error (500)
I'm unable to Attach a debugger since they messed up something with the latest versions (tried manually too https://azure.microsoft.com/en-us/blog/introduction-to-remote-debugging-on-azure-web-sites/)
I have app.UseDeveloperExceptionPage(); but I guess the site is failing during configuration so it doesn't display any other information.
So how to resolve this? I need to see the .net exception but I have no idea how to do that.
Try adding Application Insights to the app. You should see errors on startup of your application.
I would also take a look at your startup code to see if you are writing to disk anywhere during configuration or app.start. This might be the case if you are using AAD in any capacity.
You can also hit up the KUDU console by targetting https://sitename.scm.azurewebsites.net . You will be able to navigate in the debugging console to see the RAW logs from IIS. That might shed some light into the situation. See KUDU for more info.
I solved this problem like show below.HTTP 500 error interested about that is not allowed to access the server.Go to azure portal address and choose your database.Press"Set server firewall " and Allow Azure services and resources to access this server choose "Yes" save that page and refresh your service.Than you can see your data
Use the KUDU console at https://sitename.scm.azurewebsites.net
Go to web.config file and check if the process path is correct.
I used the Azure Log Stream to help figure out what was going on. As Karishma Tiwari - MSFT said, the issue ended up being my web.config file (which was built for .NET 3.5 and not 4.7)
Here's the tutorial to set up Log Streaming: https://blogs.msdn.microsoft.com/azureossds/2016/09/28/how-to-identifyreview-errors-on-php-applications-in-azure-web-apps-using-log-stream-service/
My particular app's solution was to update my Azure App Service to use .NET 3.5, in its Application Settings, like so:
For me it worked after I turned "Allow Azure services and resources to access this server
" to Yes
I got this error even though I had enabled Application Logging (Filesystem), Detailed error messages and Failed request tracing in App Service logs
This page isn’t working
mysite.azurewebsites.net is currently unable
to handle this request.
HTTP ERROR 500
However by navigating to Log stream and selecting Application Logs I could see a detailed error message:
I know this question has already been answered but here is a recent view of the Azure Portal where I found a solution to this problem
