Hello @Kanav Sharma

To integrate your Python application hosted on Azure Container Apps with Azure Application Insights, you can follow these steps:

Create an Application Insights resource in your Azure subscription if you haven't already done so.

Install the opencensus-ext-azure package in your Python application using pip. This package provides an exporter for sending telemetry data to Azure Application Insights.

Import the necessary modules in your Python application:

from opencensus.ext.azure.log_exporter import AzureLogHandler import logging

Configure the logger to use the AzureLogHandler:

logger = logging.getLogger(__name__) logger.setLevel(logging.DEBUG) logger.addHandler(logging.StreamHandler()) # Assumes the environment variable APPLICATIONINSIGHTS_CONNECTION_STRING is already set logger.addHandler(AzureLogHandler())

Add logging statements to your Python application:

logger.warning("I will be sent to Application Insights")

Deploy your Python application to Azure Container Apps.

In the Azure portal, navigate to your Application Insights resource and select "Logs" from the left-hand menu.

Run a query to view your Python application's logs: traces | where message == "I will be sent to Application Insights" This query will return all log entries with the message "I will be sent to Application Insights".

You can also view metrics for your Python application in Azure Application Insights by using the opencensus-ext-azure package to export metrics data. You can find more information on how to do this in the official documentation.

Suppose my container is running on docker and I have xyz.log file inside the docker container which is generating logs in a specific time interval. I want to send these logs to app insights (logs). How I can achieve that?

Although I am also trying to fetch live metrics from docker container/azure container app to App Insights.

Guide me here. ?

Hi @Kanav Sharma ,

Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.

To send logs from your xyz.log file inside a Docker container to Azure Application Insights, you can follow these steps:

In the Azure portal, click on "Create a resource" and search for "Application Insights" and click "Create" and fill in the required details such as the resource name, subscription, resource group, and region then click "Review + create" and then "Create", Also ensure your Docker container is set up to send logs to Application Insights and You can use the opencensus-ext-azure package for Python applications, as mentioned earlier.

In the Azure portal, search for "Log Analytics workspaces" and create a new workspace and link your Application Insights resource to this workspace by navigating to your Application Insights resource, selecting "Properties", and then selecting the Log Analytics workspace you created then navigate to your Docker container's resource in the Azure portal under "Monitoring", select Diagnostic settings and click on "Add diagnostic setting" and choose the logs you want to send to Application Insights then select your Application Insights resource as the destination.

At last, navigate to your Application Insights resource and select "Logs" from the left-hand menu to query and view your logs, for your reference use the following query to view your logs:

traces

| where message contains "your log message"

Also, you are trying to fetch live metrics from docker container/azure container app to App Insights so for these please refer the below documents:

https://learn.microsoft.com/en-us/azure/container-apps/metrics

Hi @Kanav Sharma ,

I apologize for any inconvenience caused by this.

To enable and view live metrics for your Python application in Azure Application Insights, you need to follow these steps:

First, make sure you have the Azure Application Insights SDK for Python installed. You can do this by running the following command in your terminal: pip install opencensus-ext-azure

Add the following code to your Python application. Replace YOUR_INSTRUMENTATION_KEY with your actual key from Azure:

To Enable Live Metrics in Azure Portal:

Go to your Application Insights resource in the Azure portal.

Click on Live Metrics in the left menu.

If you see a prompt, click on Turn on Live Metrics to enable it.

Once your application is running and sending data, go back to the Live Metrics section in the Azure portal.

You will see a real-time dashboard showing metrics like requests per second, failure rates, CPU usage, and more.

For more detailed instructions, check out the official Azure documentation:

https://learn.microsoft.com/en-us/previous-versions/azure/azure-monitor/app/opencensus-python

https://learn.microsoft.com/en-us/azure/azure-monitor/app/live-stream?tabs=otel

These documents provide more information on advanced configurations and usage of Application Insights with Python applications.

I hope this helps! Let me know if you have any further questions or need additional assistance.
