What shipped for running AI agents on Kubernetes by October 2026: the kubernetes-sigs Agent Sandbox project from a KubeCon preview in November 2025 to v1.0.0 in August, its four CRDs and gVisor, Kata and Firecracker runtime classes, Google's 300 claims per second and 16x growth figures, a density benchmark of 61 Kata agents versus 88, 133 and 274 per node, DRA going GA in 1.34 and locked on through 1.37, kagent, Dapr Agents 1.0, agentgateway, the Inference Extension's move into llm-d, the CNCF survey's 66 percent, and the Gartner 80 percent platform-team prediction nobody has measured.
13 minOct 5, 2026Observability in 2026: OpenTelemetry Graduated, the Collector Is Still v0.162, eBPF Instrumentation Is v0.14, and Datadog Bills $1.12B a Quarter
The non-AI state of observability in 2026 from primary sources: OpenTelemetry graduated from CNCF in May with 12,000 contributors from 2,800 companies, yet the Collector distribution is v0.162.0 with mixed component stability, profiles are alpha, messaging conventions are still Development and OBI, the donated Beyla, is v0.14.0. Datadog grew 36 percent to $1.12B in Q2, cost is the top concern for 31 percent of 1,363 surveyed engineers, and the levers that move the bill (tail sampling, OTTL filtering, cardinality limits, columnar storage, Arrow transport) live in the pipeline you run yourself.
