Profiling Workshop
This workshop shows how Database Query Performance and AlwaysOn Profiling can be used to reduce the time required for engineers to debug problems in microservices.
Service Maps and Traces are extremely valuable in determining what service an issue resides in. And related log data helps provide detail on why issues are occurring in that service.
But engineers sometimes need to go even deeper to debug a problem that’s occurring in one of their services.
This is where features such as Splunk’s AlwaysOn Profiling and Database Query Performance come in.
AlwaysOn Profiling continuously collects stack traces so that you can discover which lines in your code are consuming the most CPU and memory.
And Database Query Performance can quickly identify long-running, unoptimized, or heavy queries and mitigate issues they might be causing.
In this workshop, we’ll explore:
- How to debug an application with several performance issues.
- How to use Database Query Performance to find slow-running queries that impact application performance.
- How to enable AlwaysOn Profiling and use it to find the code that consumes the most CPU and memory.
- How to apply fixes based on findings from Splunk Observability Cloud and verify the result.
The workshop uses a Java-based application called The Door Game hosted in Kubernetes. Let’s get started!
