The Full-Host Profiler is an eBPF-based profiling solution built on OpenTelemetry that sends profiling data to Datadog using the Datadog Agent. It supports symbolication for compiled languages and is optimized for containerized environments such as Docker and Kubernetes.
@@ -19,21 +19,17 @@ The Full-Host Profiler is particularly valuable for:
- Profiling open source software components that aren't instrumented with Datadog's tracing libraries.
- Analyzing performance across multi-language processes and runtimes.
-- Identifying resource bottlenecks at the host level, including detection of noisy neighbor processes.
-
## Requirements
-For a summary of the minimum and recommended runtime and tracer versions across all languages, read [Supported Language and Tracer Versions][7].

### Container environments
For hosts running containerized workloads, Datadog recommends running the profiler inside a container:
-- **Kubernetes**: Follow the [running in Kubernetes][8] instructions.
-- **Docker**: Follow the [running in Docker][9] instructions.
+- **Kubernetes**: Follow the [running in Kubernetes][7] instructions.
+- **Docker**: Follow the [running in Docker][8] instructions.
- **Container image**: Available from the [container registry][5].
### Non-container environments
-For hosts without container runtimes, follow the instructions for [running directly on the host][10].
-
-### Configuration
-#### Local symbol upload
-For compiled languages (C/C++/Rust/Go), the profiler can upload local symbols to Datadog for symbolication when unstripped binaries are available.
-The Full-Host Profiler handles this automatically.
-
-To upload symbols using datadog-ci, see Symbol upload.
-
-### Build
-To build the Full-Host Profiler directly on your machine, run:
-
- ```shell
- make
- ```
+For hosts without container runtimes, follow the instructions for [running directly on the host][9].
## Service naming
-When using full-host profiling, Datadog captures profiles from all processes running on the host. The service name for each process depends on the `DD_SERVICE` environment variable.
+When using full-host profiling, Datadog profiles all processes on the host. Each process's service name is derived from its `DD_SERVICE` environment variable.
If `DD_SERVICE` is set, the profiler uses the value of `DD_SERVICE` as the service name. This is the recommended and most reliable approach.
@@ -80,30 +62,20 @@ If `DD_SERVICE` is not set, Datadog infers a service name from the binary name.
If multiple services are running under the same interpreter (for example, two separate Java applications on the same host), and neither sets `DD_SERVICE`, Datadog groups them together under the same service name. Datadog cannot distinguish between them unless you provide a unique service name.
