How to troubleshoot OneAgent integration with Azure App Service for Linux and containers.


Hello folks, we are integrating an App Service from Azure in Dynatrace however it seems not to be working. 

We are following this documentation

Is there any troubleshooting we can follow to solve it?

Please advise,

What kind of errors are you getting?

Have a nice day!

Hello Radek

we do not get any explicit error message. It is not reporting in our tenant so we would like to troubleshoot to find out if anything wrong in the configuration.

The documentation mentions that it might occur conflict with Azure Application Insights. This application was instrumented before in Azure Application Insights. 

Do you think that might be the case? If so is it possible to have the application reporting both in DT and Azure Application Insights?

If Azure Application Insights is enabled then turn this feature off before instrumentation. I would still verify the network connections to the AG and from the AG to the DT - to make sure everything is open.

Have a nice day!

Thank you Radek for the reply. After enabling Dynatrace monitoring is it possible to turn on Application Insights back? Is it possible to have to both monitorings concurrently?

@alexrp25, below the answer we received some time ago from a Dynatrace contact, on a similar question. I figured it might be useful to share:

App Insight is often used in development environments and not so much in production environments.

Dynatrace has tested a lot in all kinds of different combinations with OneAgent and AppInsight. The overhead moments are related to Azure App Services issues. Does the customer use Azure App Services and does the customer want to use AppInsight and Dynatrace OneAgent? If so, advice is to test what the overhead is in an acceptance environment
• without agent,
• with only AppInsight,
• with only Dynatrace OneAgent,
• with both Dynatrace OneAgent and AppInsight.

In short OneAgent and AppInsights can work in parallel at a certain level, depending on which functionalities are enabled in AppInsight. This is why we give a warning when it is on. Second is the instrumentation engine, when they use their own profiler. These cannot be used together. So they will have to disable AppInisght .NET profiler. In other words, they don't have to disable AppInsight completely.

Hi @alexrp25 

Make sure that you set the environment variable LD_PRELOAD, which points to the downloaded OA, before starting your application.

We have unsuccefully been trying install OA using the default Linux Azure App Service. We get an exit error code 4. We see the downloaded the /tmp directory but somehow it fails to install.
