Application Insights

  • Request rates, response times, and failure rates
  • Dependency rates, response times, and failure rates
  • Exceptions
  • Page views and load performance
  • Performance counters
  • Host diagnostics
  • Diagnostic trace logs
  • Custom events and metrics

Ways to get started monitoring and analyzing app performance:

  • At run time: without change in code
  • At development time: add to code
  • Instrument your web pages (client-side telemetry)
  • Analyze mobile app usage (Visual Studio App Center)
  • Availability tests: ping regularly from azure servers

log-based metrics

  • log-based metrics: Kusto queries from stored events (require processing to produce the result)
  • Standard metrics: pre-aggregated time series. (near real time)

Availability test

Up to 100 availability tests per Application Insights resource

  • URL ping test (classic): relies on the DNS infrastructure of the public internet
  • Standard test (Preview):
  • Custom TrackAvailability test: use TrackAvailability() method to send data to Application Insight
  • Multi-step test: Only available from visual studio , multi request or authentication test scenarios (Custom TrackAvailability works as well)

Application Map

Troubleshoot app performance

  • Components are different from "observed" external dependencies such as SQL, Event Hubs, etc. which your team/organization may not have access to (code or telemetry).
  • Components run on any number of server/role/container instances.
  • Components can be separate Application Insights instrumentation keys (even if subscriptions are different) or different roles reporting to a single Application Insights instrumentation key.

Progressive discovery of the components

Alert type

  • Metric alert: Metric data is stored in the system already pre-computed. Metric alerts are useful when you want to be alerted about data that requires little or no manipulation. We recommend using metric alerts if the data you want to monitor is available in metric data. (stateful - only notifying once when alert is fired and once when alert is resolved)

  • Log alert: Log alerts allow you to perform advanced logic operations on your data. (KQL for data manipulation using log alerts).

  • Activity Log alert: Activity logs provide auditing of all actions that occurred on resources. Use activity log alerts to be alerted when a specific event happens to a resource, for example, a restart, a shutdown, or the creation or deletion of a resource. (Stateless)

  • Prometheus alerts (preview): Prometheus alerts are primarily used for alerting on performance and health of Kubernetes clusters (including AKS).

  • Mastering Event-Driven Design

    PLEASE RSVP SO THAT WE KNOW HOW MUCH FOOD WE WILL NEED Are you and your team struggling with event-driven microservices? Join us for a meetup with Mehmet Akif Tütüncü, a senior software engineer, who has given multiple great talks so far and Allard Buijze founder of CTO and founder of AxonIQ, who built the fundaments of the Axon Framework. RSVP for an evening of learning, delicious food, and the fusion of creativity and tech! 🚀 18:00 – 🚪 Doors open to the public 18:15 – 🍕 Let’s eat 19:00 – 📢 Getting Your Axe On Event Sourcing with Axon Framework 20:00 – 🍹 Small break 20:15 – 📢 Event-Driven Microservices - Beyond the Fairy Tale 21:00 – 🙋‍♀️ drinks 22:00 – 🍻 See you next time? Details: Getting Your Axe On - Event Sourcing with Axon Framework In this presentation, we will explore the basics of event-driven architecture using Axon Framework. We'll start by explaining key concepts such as Event Sourcing and Command Query Responsibility Segregation (CQRS), and how they can improve the scalability and maintainability of modern applications. You will learn what Axon Framework is, how it simplifies implementing these patterns, and see hands-on examples of setting up a project with Axon Framework and Spring Boot. Whether you are new to these concepts or looking to understand them more, this session will provide practical insights and tools to help you build resilient and efficient applications. Event-Driven Microservices - Beyond the Fairy Tale Our applications need to be faster, better, bigger, smarter, and more enjoyable to meet our demanding end-users needs. In recent years, the way we build, run, and operate our software has changed significantly. We use scalable platforms to deploy and manage our applications. Instead of big monolithic deployment applications, we now deploy small, functionally consistent components as microservices. Problem. Solved. Right? Unfortunately, for most of us, microservices, and especially their event-driven variants, do not deliver on the beautiful, fairy-tale-like promises that surround them.In this session, Allard will share a different take on microservices. We will see that not much has changed in how we build software, which is why so many “microservices projects” fail nowadays. What lessons can we learn from concepts like DDD, CQRS, and Event Sourcing to help manage the complexity of our systems? He will also show how message-driven communication allows us to focus on finding the boundaries of functionally cohesive components, which we can evolve into microservices should the need arise.
