Add unified profiling feature gate config keys by jbachorik · Pull Request #11090 · DataDog/dd-trace-java

jbachorik · 2026-04-13T12:03:30Z

What Does This Do

Adds unified profiling.<feature>.enabled configuration keys for all GA profiling features, following the pattern established by profiling.heap.enabled:

profiling.cpu.enabled (default: true) — gates CPU profiling for both JFR (jdk.ExecutionSample, jdk.NativeMethodSample, jdk.CPUTimeSample) and ddprof
profiling.walltime.enabled (default: true) — gates wall-clock profiling for ddprof (JFR timeline events are intentionally excluded — they serve queueing-time and blocking-event purposes beyond wall-clock profiling)
profiling.exception.enabled (default: true) — gates JFR exception profiling (datadog.ExceptionSample, datadog.ExceptionCount)
profiling.io.enabled (default: true) — gates JFR I/O profiling (jdk.FileRead/Write/Force, jdk.SocketRead/Write)
profiling.lock.enabled (default: true) — gates JFR lock profiling (jdk.JavaMonitorEnter, jdk.BiasedLock*)
profiling.thread.enabled (default: true) — gates JFR thread lifecycle profiling (jdk.ThreadStart/End)
profiling.direct.memory.enabled (default: false) — unified replacement for deprecated profiling.directallocation.enabled; old key still works as fallback

Also:

Adds PROFILING_ALLOCATION_ENABLED_DEFAULT = true constant (was dynamic-only before)
Updates DD_PROFILING_HEAP_ENABLED and DD_PROFILING_ALLOCATION_ENABLED metadata defaults to "true"
Deprecates PROFILING_HEAP_ENABLED_DEFAULT (dynamic default) and PROFILING_DIRECT_ALLOCATION_ENABLED constants
Adds === Feature Gates === section to profiler flare report

Motivation

PROF-10633 — Revisit and unify profiling settings.

Users had no consistent, feature-level way to disable individual profiling modes without reaching into backend-specific knobs (profiling.ddprof.cpu.enabled, profiling.ddprof.wall.enabled, etc.). The new unified keys provide a single toggle per feature that applies to both JFR and ddprof backends.

Configuration Design

Two-tier gate hierarchy

Each profiling feature is gated at two levels. The unified key is checked first; if it passes, backend-specific keys apply their own inner overrides.

    end

    subgraph EXC["profiling.exception.enabled - default: true"]
        EXC_JFR["JFR: ExceptionSample, ExceptionCount"]
    end

    subgraph IO["profiling.io.enabled - default: true"]
        IO_JFR["JFR: FileRead, FileWrite, FileForce,<br>SocketRead, SocketWrite"]
    end

    subgraph LOCK["profiling.lock.enabled - default: true"]
        LOCK_JFR["JFR: JavaMonitorEnter, BiasedLock"]
    end

    subgraph THR["profiling.thread.enabled - default: true"]
        THR_JFR["JFR: ThreadStart, ThreadEnd"]
    end

    subgraph DM["profiling.direct.memory.enabled - default: false"]
        DM_INST["ByteBuffer.allocateDirect,<br>DirectByteBuffer ctor,<br>FileChannelImpl.map"]
    end

Config resolution for `dd.profiling.direct.memory.enabled`

This key replaces the deprecated dd.profiling.directallocation.enabled. The old key is honoured as an alias so existing deployments are unaffected.

Additional Notes

All new keys default to true so existing deployments are unaffected
profiling.direct.memory.enabled defaults to false to preserve backward compatibility with profiling.directallocation.enabled
The backend-specific keys (profiling.ddprof.cpu.enabled, etc.) remain as inner overrides for advanced use
Gates are evaluated once at recording start; profiling does not use Remote Config, so a disabled feature stays disabled for the recording lifetime

Contributor Checklist

Format the title according to the contribution guidelines
Assign the type: and (comp: or inst:) labels in addition to any other useful labels
Avoid using close, fix, or any linking keywords when referencing an issue
Use solves instead, and assign the PR milestone to the issue
Update the CODEOWNERS file on source file addition, migration, or deletion
Update public documentation with any new configuration flags or behaviors
