Current HEC log ingestion does not usefully index nested json. Business Justification Our organization is adopting OpenTelemetry as the standard observability framework for collecting logs, metrics, traces, and events across cloud, on-premises, and application environments. While OpenTelemetry has become the industry standard for telemetry collection, the current SIEM integration options are either limited or require custom ingestion pipelines. Native OpenTelemetry support would simplify integrations, reduce operational overhead, improve telemetry consistency, and enable broader security visibility across modern infrastructure. Requested Capability Native OpenTelemetry Data Ingestion Support direct ingestion of: OpenTelemetry Protocol (OTLP) over gRPC OTLP over HTTP OpenTelemetry Collector forwarding Structured OpenTelemetry logs Metrics relevant to security monitoring Distributed traces OpenTelemetry Schema Awareness Automatically recognize and normalize standard OpenTelemetry fields such as: service.name service.namespace service.version host.name cloud.provider cloud.region deployment.environment trace_id span_id severity_number severity_text Resource attributes Instrumentation scope attributes Security Correlation Enable correlation between: Logs and traces Infrastructure telemetry and security alerts Application events and security incidents User actions across distributed services Examples: Correlate authentication failures across microservices using Trace IDs. Trace lateral movement activity across distributed applications. Link API abuse indicators to backend service traces. OpenTelemetry Collector Integration Provide validated configurations and documentation for: OpenTelemetry Collector Azure Monitor Exporter Kubernetes deployments Containerized workloads AWS, Azure, and GCP environments Detection Content Provide out-of-the-box dashboards and detections that leverage OpenTelemetry data: Authentication anomalies API abuse patterns Service-to-service communication anomalies Application compromise indicators Distributed denial-of-service indicators Suspicious trace patterns Performance and Scalability Support: High-volume OTLP ingestion Multi-tenant collection architectures Collector-based aggregation Sampling-aware analytics Buffered and resilient ingestion mechanisms Expected Benefits Operational Benefits Reduced custom parser and connector maintenance Faster onboarding of new applications Standardized telemetry pipeline Improved data quality and consistency Security Benefits Better visibility into modern cloud-native environments Enhanced attack-path analysis Improved incident investigation through trace correlation Stronger detection coverage across distributed systems Business Benefits Reduced integration costs Faster deployment of new services Alignment with industry standards Future-proof telemetry architecture Priority High Use Cases Correlate security events across microservices using Trace IDs. Investigate suspicious application behavior end-to-end. Monitor Kubernetes workloads through OpenTelemetry Collectors. Centralize observability and security telemetry using a single standard. Reduce dependence on vendor-specific agents and collectors. Desired Outcome The SIEM should be capable of ingesting, parsing, normalizing, correlating, and analyzing OpenTelemetry telemetry natively, allowing organizations to leverage OpenTelemetry as a first-class data source for security monitoring, threat detection, and incident response. Impact: High value for organizations adopting cloud-native architectures, Kubernetes, Azure/AWS/GCP services, and modern observability platforms.
