It is the most common technique for profiling and doesn't require any modification to your code. There are two main techniques to achieve this: CPU-Sampling and Instrumentation.ĬPU-Sampling is a non-invasive method which takes snapshots of all the stacks at a set interval. This tool can help you identify where you are spending CPU time during the execution of your application. ![]() ![]() Profiling is a technique where you take small snapshots of all the threads in a running application to see the stack trace of each thread for a specified duration. There are two types of diagnostics tools you may want to use: profilers and memory analyzers. In these cases, platform or programming language specific diagnostic tools come into play and are useful to debug a memory leak, profile the CPU usage, or the cause of delays in multi-threading. ![]() In some scenarios, analyzing the memory consumption and drilling down into why a specific process takes longer than expected may require additional measures. Besides Logging, Tracing and Metrics, there are additional tools to help diagnose issues when applications do not behave as expected.
