I am using java agent to collect telemetry data and send it to application insights.
currently I have configured sampling and log level in applicationinsights.json.
Is there a way to change this parameters at runtime? without restarting the service?
I have tried to change this properties at runtime e.g: APPLICATIONINSIGHTS_SAMPLING_PERCENTAGE but this does not seem to work
I can see the same issue registered in MS Q&A Forum on the Same date and thanks to #AnuragSingh-MSFT for providing the solution to the Application Insights Information to the user:
Is there a way to change these parameters at runtime? without restarting the service?
App Restarts automatically after updating the Application Setting in the Configuration in Azure Hosted Application because these settings are read during app start for configuration and that will be stored in the memory.
Refer to the Q&A #1166345 for more information on Application Insights Sampling.

I am working on the ASP.Net MVC 4.8 application. It does have Logs file log4net and it was deployed in on-premises. Now it has been migrated to Azure. Now I am trying to find out some errors and other logs information however I am not able to find where to go and look for the logfile. I have two interest, 1 check the error messages and any log information.
If I need to make some changes what would be the easiest and straightforward way to capture logs and view them in Azure portal. As you can see in the picture below unter Monitoring there are many ways are given to see the logs but I am not sure where to go.
The app service will create an application insights of the same name.
This application Insights will contain all the logs regarding the web app along with performance data and other telemetry data too.
You can view logs live under live metrics tab in application insights of the same name as web app .
Here I have deployed a simple mvc app which logs using Ilogger (typical boilerplate app which visual studio provides ) . IT will log once I refresh the page.
Refer these MS DOCS on application insights
I have two project Web app and Web API. I have integrated application insight to them simply by right-click on my project and choosing option configure application insight. I can see my live metrics working fine but in the Overview page I don't see any movement in graphs. I have attached the screenshot of the not-working-graph.
I just noticed that when i am integrating application normally as stated above then its working fine but when i am trying to change the application insight by changing the key of application insight at specific location then the issue is creating. Can anyone help me why its working differently just by changing the application key?
In general, The Instrumentation Key is the bridge that binds your application to Application Insights through which you monitor all the changes that occur in your application.
Instrumentation Key is the key integration point between your application and the Application Insights. If you create the Application Insights directly using Visual Studio; Visual Studio takes care of linking between your application and the key.
So changing the Instrumentation key from Application insights can make the live metrics work differently since the link is broken. If you are trying to add another resource's i.e., Application insights' instrumentation key (depending upon your business requirement), then you can see that the metrics get logged in that resource.

Would like to use Application insights especially, "Azure live metrics stream" feature on existing PROD Azure service fabric workloads to do performance analysis.Is service fabric has built-in integration with Azure Application Insights?
Is it possible do it in code less manner like how Application insights can be enabled via portal for web Apps/Azure functions? If not, why?
Then, how to do it code based manner? Any reference to do code changes would be helpful.
What is the difference between code less & code based monitoring? When to choose one over another? Our requirement is to study performance of application (deployed on various nodes of PROD service fabric cluster) under different load.
Please clarify above list of queries.

You could leverage Windows Azure Diagnostics (WAD) extension to sink SF cluster logs and/or Perf metrics into App Insights - Configuring Application Insights with WAD
There is no way to monitor an application running in SF via AppInsights without a small amount of coding.
Then, how to do it code based manner? Any reference to do code changes would be helpful.
Here you go - Monitor and diagnose an ASP.NET Core application on Service Fabric using Application Insights.

As I said, to monitor your app you have to code. Although it's super simple. Other from that, here is a general recommendation - Event analysis and visualization with Application Insights:
It is recommended to use EventFlow and WAD as aggregation solutions,
because they allow for a more modular approach to diagnostics and
monitoring, i.e. if you want to change your outputs from EventFlow, it
requires no change to your actual instrumentation, just a simple
modification to your config file. If, however, you decide to invest in
using Application Insights and are not likely to change to a different
platform, you should look into using Application Insights' new SDK for
aggregating events and sending them to Application Insights. This
means that you will no longer have to configure EventFlow to send your
data to Application Insights, but instead will install the
ApplicationInsight's Service Fabric NuGet package.
Here is the link to the best practices - Monitoring and diagnostics on SF platform.
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 using application insight for measuring performance and also storing some telemetry data of my web application and it was working fine till last month.
But from last month I am unable to see any traffic in app insight. In last month just I have added one slot in my app service. I have checked instrumentation key, it's same and correct and there is no change in application settings and configuration in app service.
Could you please suggest me if any additional settings I need to take care ?
I suspect this issue is due to adding of slot because in other environment it's working fine.
You could go to Visual Studio configure Application Insights through there and then redeploy the application to slot.
For more information, you could refer to this doc: Application Insights support for Multiple Environments, Stamps and App Versions, , specifically the 'Multi Stamp Support'.
How are you enabling application insights for the App in Azure Web App? Are you using extensions or do you take nuget dependency at build time?
If using extension, please navigate to this url to find the status of application insights enablement: https://yoursitename.scm.azurewebsites.net/ApplicationInsights
Have you ensured that that instrumentation key is available in all slots? This is most likely an instrumentation key issue.
