Profiling: Identifying App Performance Bottlenecks with No Code Changes

One of the most frustrating parts of troubleshooting modern applications is identifying the root cause of performance issues. New tools have made it easier than ever to quickly identify which service in a complex, distributed environment is to blame for problems, but generally speaking, it’s still quite difficult to identify exactly why performance is bad in modern applications. Some vendors offer code profiling support, but typically, enabling the profiler has significant performance impacts, and it’s difficult to use the profiling data in a meaningful way.

Join us for this hands-on workshop designed for SRE and DevOps professionals looking to find the root cause of performance problems faster. In this session, you'll discover how to leverage Splunk's AlwaysOn Profiling feature, powered by OpenTelemetry, to troubleshoot and rapidly fix a performance issue in a Java application with ease.

Through a guided scenario, you will:

• Deploy a simple, un-instrumented Java application.
• Learn how to install the Splunk OpenTelemetry Collector in just a few steps.
• Enable automatic discovery, configuration, and instrumentation for existing Java deployments to start streaming observability data to Splunk Observability Cloud.
• Enable automatic AlwaysOn Profiling support without changing any code in your application.
• Learn how Splunk Application Performance Monitoring interprets and makes it easy to determine the root cause of performance issues by showing you valuable data from the profiler.
• Fix a real performance problem in the sample application, after being directed by AlwaysOn Profiling to exactly which line of code is causing the problem.

By the end of this workshop, you’ll see the power of code profiling through identifying and repairing a serious application performance problem. This session is perfect for new Splunk customers - no prior knowledge of Splunk or OpenTelemetry is required.
