Zenoss Cloud gRPC Services
First-party proto3 service contracts published at github.com/zenoss/zenoss-protobufs and released as a Go module (v1.5.5, 2026-07-27). DataReceiverService carries unary PutEvents, PutMetrics and PutModels plus client-streaming PutEvent, PutMetric and PutModel; DataRegistryService registers metric and definition metadata; CredentialManagement reads stored credentials; CollectionConfigService streams collection configuration to probes. RPCs carry google.api.http annotations binding them to the same /v1 REST paths, so the protobufs are the machine-readable contract behind the ingest surface.
