Junos Telemetry Interface

  • Consolidated (atomic) statistics delivery for next-hop groups and conditional next-hop groups in JTI (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.1R1, Junos telemetry interface (JTI) supports consolidated (atomic) data. Statistics for next-hop groups and conditional next-hop groups will be delivered in a single "atomic" protocol data unit (PDU) instead of across multiple PDUs.

  • Enhanced chassis statistics for JTI (PTX10001-36MR, PTX10003, PTX10004, and PTX10008)—Starting in Junos OS Evolved Release 22.1R1, JTI supports streaming and ON_CHANGE platform statistics per OpenConfig module openconfig-platform.yang version 0.12.1. Use Juniper proprietary remote procedure call (gRPC) and gRPC Network Management Interface (gNMI) to export statistics to an outside collector.

  • INITIAL_SYNC support for optics and transceiver telemetry statistics (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.1R1, JTI supports INITiAL_SYNC for leaf nodes under resource paths /junos/system/linecard/optics/ and /components/component/transceivers/.

  • MACsec statistics (PTX10008)—Starting in Junos OS Evolved Release 22.1R1, JTI provides ON_CHANGE and periodic streaming of Media Access Control Security (MACsec) statistics by means of Juniper proprietary gRPC and gNMI from a device to an outside collector. This feature supports the data model openconfig-macsec.yang. Additional leaves outside the scope of the data model are augmented.

    To stream MACsec statistics, include the resource path /macsec/ in a subscription.

  • Packet Forwarding Engine pipeline sensors (PTX10001-36MR, PTX10008, and PTX10016)—Junos OS Evolved Release 22.1R1 introduces support for pipeline sensors with JTI. The pipeline sensors provide telemetry device monitoring by delivering NPU and ASIC counters from a device to an outside collector. The four packet and drop counter categories are interface, lookup, queueing, and host interface. Subscribe to the resource path /components/component/integrated-circuit/pipeline-counters to export all pipeline counters, or use /components/component/integrated-circuit/pipeline-counters/packet/ or /components/component/integrated-circuit/pipeline-counters/drop/ to provide packet-only or drop-only counters.

    The pipeline sensors support both zero-suppression and initial sync. The zero-suppression feature streams only non-zero values. The initial sync (init-sync) feature streams all values once after the initial subscription. This one-time-only bucket of values includes zero values even if zero-suppression is enabled.

    You can use native (UDP) and Juniper proprietary gRPC and gNMI to stream counters.

  • System, CPU, and memory statistics (ACX7100-32C, PTX10001-36MR, PTX10003, PTX10004, PTX10008 and PTX10016)—Starting in Junos OS Evolved Release 22.1R1, JTI provides periodic streaming of system statistics, CPU statistics, and memory-related parameters. Statistics support the health-monitoring application. This feature supports the data model openconfig-system.yang version 0.10.0. It is supported using Juniper proprietary gRPC and gNMI supported.
