Abstract

Modern applications behave quite differently in production compared to development or testing environments. Outlier requests and accounts, edge cases, configuration changes, security features, and request spikes can make an application behave in unexpected ways. This may lead to poor CPU and memory performance, which can be costly and result in an undesirable end-user experience. Datadog Continuous Profiler enables you to quickly uncover costly bugs and identify code improvements to help you reduce infrastructure costs and enhance end-user experience. In this course, you'll learn how to use Continuous Profiler to diagnose code performance problems in an application.

Learning Objectives

By the end of this course, you'll be able to do the following:

  • Determine when and how to use continuous profiling for diagnosing application performance problems
  • Apply a performance diagnostic methodology to troubleshoot code performance issues using profile types, endpoint profiling, and comparing profiles in Continuous Profiler

Primary Audience

Application developers who aren't familiar with diagnosing code performance problems, performance engineers, SREs
