Scale OpenTelemetry Prometheus scraping with the Target Allocator, explicit monitor selectors, collector identity, RBAC, and duplicate-target diagnostics.
Enrich OpenTelemetry telemetry with Kubernetes metadata using stable pod identity, explicit association rules, narrow RBAC, and bounded collector caches.
Build a local OpenTelemetry Collector pipeline in WSL, verify OTLP ingestion, and reason about memory limits, queues, retries, and shutdown loss.
Engineer Collector memory limits, batch processors, exporter queues, retries, and persistent storage with explicit backpressure, loss, and duplication tradeoffs.
How tail sampling buffers complete traces, evaluates outcome-aware policies, controls memory, and preserves representative telemetry during failures.
How to design Collector pipelines for metrics, logs, and traces without creating an unbounded queue, telemetry leak, or new single point of failure.
