Find CPU, memory, and IO bottlenecks, broken down by method name, class name, and line number, to significantly reduce end-user latency and infrastructure costs.
Low impact in production
Continuous profiler runs in production across all services by leveraging technologies such as JDK Flight Recorder to have minimal impact on your host’s CPU and memory usage.
Getting started
Profiling your service to visualize all your stack traces in one place takes just minutes.
Instrument your application
Guide to using the profiler
The Getting Started with Profiler guide takes a sample service with a performance problem and shows you how to use Continuous Profiler to understand and fix the problem.
Explore Datadog profiler
After you configure your application to send profiles to Datadog, start getting insights into your code performance.
By default, profiles are retained for seven days, and metrics generated from profile data are retained for one month.
Profile types
See Profile Types for descriptions of the kinds of profile data collected for each supported language.
Search profiles by tags
Use tags to search profiles across any dimension—whether it’s a specific host, service, version, or any combination.
Track function performance over deployments
Obtain key profiling metrics from services such as top CPU usage by method, top memory allocations by thread, and CPU usage by version to visualize in your dashboards.
Connect traces to profiling data
Application processes that have both APM distributed tracing and continuous profiler enabled are automatically linked, so you can move directly from span information to profiling data on the Code Hotspots tab to find specific lines of code related to performance issues.
Find changes in performance by comparing profiles
Comparing similar profiles from different times, environments, or deployments can help you understand the possible causes of and solutions to performance problems. The Datadog profiler offers comparison visualizations to make sense of why profiles are different based on time frames or tags that you scope by.
