Junos Telemetry Interface

  • Chassis management error (cmerror) sensor support (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.2R1, use the resource path /components/component/integrated-circuit/pipeline-counters/ to stream fine-grain, per-integrated circuit (IC) telemetry data that identifies the IC health and any packet drops or errors on the iC. This data is per router and per iC on a router. This feature supports the data model openconfig-platform-pipeline-counters.yang and is supported using Juniper proprietary gRPC remote procedure call (gRPC) and gRPC network management interface (gNMI).
