What is Continuous Profiler in Datadog?
Continuous Profiler is an always-on, low-overhead code profiler that runs in production, capturing where CPU time, memory allocations, and lock contention are actually being spent inside your application's code - down to the specific function or line.
Unlike a one-off profiling session, it runs continuously with sampling-based collection (rather than tracing every single call), which keeps overhead low enough to leave enabled in production all the time.
Profiles are correlated with APM traces, so a slow endpoint in the trace view can be linked directly to the exact code path consuming the most CPU during that request.
Continuous Profiler is designed to run:
