feat: replace HyperDX with configurable OTLP tracing - #480
Conversation
WalkthroughThe logger now exports traces through configured OTLP endpoints and flushes through the tracer provider. HyperDX configuration is removed from deployment and environment files. Documentation describes VictoriaTraces setup, verification, and debugging. ChangesOTLP tracing migration
Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Authenticated OTLP deployments may expose credentials over cleartext HTTP. This should be prevented before merge while retaining credential-free HTTP support for VictoriaTraces. Sequence Diagram(s)sequenceDiagram

OpenTelemetry JavaScript exporter-trace-otlp-http 0.49.1 OTEL_EXPORTER_OTLP_HEADERS OTEL_EXPORTER_OTLP_TRACES_HEADERS HTTP endpoint source
💡 Result:
In OpenTelemetry, header configuration for the OTLP exporter is managed via standardized environment variables [1][2][3]. The variables OTEL_EXPORTER_OTLP_HEADERS and OTEL_EXPORTER_OTLP_TRACES_HEADERS are used to specify key-value pairs for HTTP or gRPC requests [1][2]. Key details regarding these variables include: 1. Precedence: Signal-specific environment variables (e.g., OTEL_EXPORTER_OTLP_TRACES_HEADERS) take precedence over the generic, global variable (OTEL_EXPORTER_OTLP_HEADERS) [4]. 2. Format: Both variables expect a list of key-value pairs formatted as a W3C Baggage-compliant string (e.g., key1=value1,key2=value2) [2][3][4]. Semi-colon delimited metadata is not supported [2][3]. 3. JavaScript Implementation Context: For the @opentelemetry/exporter-trace-otlp-http package (version 0.49.1), custom headers can also be configured programmatically via the headers option in the collectorOptions object when instantiating the OTLPTraceExporter [5][6][7]. Note that there have been historical discussions and issues within the OpenTelemetry JavaScript SDK regarding the consistent adherence of all exporters to these standardized environment variables [8]. Users should ensure their specific SDK version and exporter implementation align with the latest OpenTelemetry configuration specifications [1][3].

Sensitive Data Exposure
Reachability: Internal
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information
Do not send configured OTLP headers over an unencrypted endpoint.
The OTLP exporter reads standard header environment variables, which can contain authorization tokens or API keys. Reject non-HTTPS endpoints when either header setting is nonempty. Keep the documented credential-free VictoriaTraces HTTP endpoint usable.
