How they use Nebius AI Cloud
Datadog lists Nebius, Inc. as a United States subprocessor providing AI services. Its register identifies subprocessors by their locations and the services they provide to Datadog.
Datadog’s merged Agent code preserves a device specification observed on a Nebius H200 node running dynamic MIG. The observed resource pool was computeinstance-u00gcpath9ehe3c8xe. MIG splits one physical GPU into separately allocated compute and memory slices so separate workloads can share it.
The associated pull request reports a test with two pods using slices labelled 1g.35gb and 1g.18gb on the same GPU. Each pod’s metrics were attributed to its own MIG UUID. Validation also covered attribution after initial allocation, its removal after pod deletion, re-attribution after pod recreation, and automatic recovery after an Agent restart.
The implementation resolves Kubernetes DRA resource claims into device identities the GPU check can use for pod tagging. Allocated device names are scoped to a resource pool rather than being NVML UUIDs. Node-local CDI specifications map those names to device nodes, which the implementation resolves through NVML to MIG UUIDs. Those UUIDs let the Agent associate GPU metrics with the containers and pods holding the allocated slices.

For Datadog’s Nebius H200 monitoring validation, zhuminyi reports two pods using 1g.35gb and 1g.18gb slices on the same GPU, each attributed to its own MIG UUID. The PR records resource pool computeinstance-u00gcpath9ehe3c8xe and explains how node-local CDI specifications resolve DRA allocations for GPU-metric pod tagging. Tests cover allocation, deletion, recreation and Agent restart recovery.
