Azure Application Insights can be a collection point for Python Metrics that you can query and filter against.  We can send Open Census metrics from anywhere in the world into Azure Application Insights. This lets us see our program metrics from any browser that can reach the Azure console.  Application Monitor gives us a zero admin performance console. OpenCensus metrics are recorded in Application Insights as customMetrics . Every metric sent is a row in Application Insights. The Azure  OpenCensus Azure Exporter  adds a standard set of attributes that appear in App Insights as CustomDimensions .  We can add additional custom dimensions (attributes) to any metrics record sent Azure Application Insights. All metrics are actually captured in a customMetrics table that we can query against. Execution pre-requisites You have an Azure login You have created an Azure Application Insights Application ...

We can capture Python performance metrics in Azure Application Insights. This will let us see our program performance from anywhere that can reach the Azure console.  I've used this to capture a variety of Python data manipulation and process timing without having to stand up any metrics databases or dashboards. I wanted to plot basic internet performance information from data generated from two different machines in two different locations.  The source code is on GitHub here freemansoft/speedtest-app-insights . That project runs speedtest.net measurements and then posts them to Azure Application Insights.  We can create charts for any of the data gathered as part of this process. Target Graphic We want to create a graphical tile that shows our connection ping time broken out per test machine. The program code above posts new ping time data every 5 minutes.  This graphic shows the ping results for the last 4 hours. Execution pre-requisites You have an Azure login You...

Application Insights is an Azure based application performance dashboard that can monitor applications deployed inside, or outside, Azure.  Application Insights SDKs are available for a variety of languages with a heavy focus on standard library web driven applications or services. This blog entry describes how easy it is to enable Application Insights for a Spring wired Java application that does not use any of the out-of-the-box supported web hooks. In this case, we are enabling Java / JMX monitoring of a custom Spring application running in my home lab. Performance information is gathered by Application Insights where it is displayed in the Azure Portal. I did this work as part of building a message driven application that had no true web interface. The application runs in a container that does not support tomcat or web filters normally used to enable Application Insight. Microsoft does a good job of describing how to monitor Java Tomcat, Struts, Spring MVC and other sta...
