TL;DR: Filtering, deleting fields, and sampling at the pipeline layer can sharply reduce telemetry ingestion costs without changing application code, according to Bindplane. The governance question is not whether to collect less data, but how to preserve operationally useful signals while removing high-volume noise and unnecessary field baggage.
Editorial analysis by NHI Mgmt Group, based on content published by Bindplane: “How to Reduce Data Costs with OpenTelemetry and Bindplane”.
Key questions
Q: How should security teams reduce telemetry overload without losing useful signals?
A: Start by separating data needed for compliance retention from data needed for live investigation.
Q: Why do telemetry pipelines matter for governance rather than just engineering efficiency?
A: Because they decide what data is allowed to exist in the observability system at all.
Q: What mistakes do teams make when sampling log and trace data?
A: The most common mistake is sampling streams that contain rare but important failures, which destroys forensic value.
Practitioner guidance
- Implement severity-based filtering on expensive destinations Start by removing debug and info logs from high-cost sinks while preserving warn, error, and fatal records for operational response.
- Use conditional exclusions for repetitive health checks Exclude known low-value traffic such as liveness and readiness probes, and keep each endpoint in its own condition group so the logic matches correctly.
- Delete high-cardinality fields before they reach indexing Strip session_token, container_id, k8s.pod.uid, thread_id, and build_sha from branches that do not need those attributes for investigation.
Bottom line: Pipeline filtering can reduce ingestion spend quickly, but the control only works safely when teams distinguish between noisy telemetry and evidence-bearing telemetry.

Telemetry governance is now a control-plane issue, not an afterthought. Once telemetry is filtered in-pipeline, the organisation has already made a decision about what evidence survives. That means cost, detection coverage, and auditability are linked at the point of collection, not just at the point of storage. For identity and access programmes, this is especially important because session data, token traces, and privileged activity logs may be reduced before they ever reach a SIEM. Practitioners should treat pipeline policy as part of security governance, not just observability tuning.
A question worth separating out:
Q: What should organisations keep at full fidelity in telemetry pipelines?
A: Keep error, fatal, privileged, and incident-response data at full fidelity whenever those records are needed for investigation or accountability. Sampling and aggressive filtering belong on repetitive, low-risk streams where summary behaviour is enough and evidence loss will not undermine the control objective.
