Variable ATTR_PROCESS_EXECUTABLE_BUILD_ID_HTLHASHConst Experimental

Note

GNU and Go build IDs may be stripped or unavailable in some environments (e.g., Alpine Linux, Docker images). This attribute provides a deterministic build ID computed by hashing the first and last 4096 bytes of the file along with its length:

Input   ← Concat(File[:4096], File[-4096:], BigEndianUInt64(Len(File)))
Digest  ← SHA256(Input)
BuildID ← Digest[:16]
Copy

The result is the first 16 bytes (128 bits) of the SHA256 digest, represented as a hex string.

This attribute is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
