Description

In this lab, you will be profiling a Java Spring Application that you will create in a Compute Engine IDE. The application has a couple of APIs. One contains a long-running operation creating a performance bottleneck. There are a few Google Cloud Services that can help you to monitor the application performance. This lab is the last in a series of three that focuses on Cloud Debugger. You are encouraged to complete the lab on Cloud Profiler before performing this lab.

Application performance should be regularly optimized to minimize latency issues. Users often find it difficult to monitor the performance or latency issues. Google Cloud provides a suite of tools to help you overcome application performance management issues. These tools provide insights on how your code performs and allows you to take defensive actions to fix any problems. You will investigate the following tools in the context of the sample Java application to understand how they work first-hand in a series of labs:

  • Cloud Trace helps you analyze the latency of applications. It shows a summarised view of the APIs and the time taken to execute in near real-time.
  • Cloud Profiler helps you analyze performance issues, CPU utilization, and memory usage. It helps your application to perform better by optimizing intensive function calls and code.
  • Cloud Debugger helps you debug your production code by loading the production code in Google Cloud. As a developer, there are certain times when you notice issues in production. To debug the issues without taking the application offline or disturbing the user latency, you can use Cloud Debugger.

Learning Objectives

Upon completion of this lab you will be able to:

  • Use the Cloud Debugger Java agent for Google Compute Engine to debug applications
  • Create snapshots of applications to view call stacks and variable state of running applications
  • Instrument logs in applications without modifying the application source code

Intended Audience

  • Software developers
  • QA engineers
  • Anyone interested in debugging
  • Monitoring teams

Prerequisites

You should possess:

  • A basic understanding of Java
  • A basic understanding of the Spring Boot framework is helpful but not required
