Junos Telemetry Interface

  • BGP enhanced state sensors (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 supports Junos Telemetry Interface (JTI) streaming new BGP resource paths.

    [See Telemetry Sensor Explorer.]

  • Chassis management configuration and counter support (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 supports JTI streaming of chassis management error (cmerror) configuration and counters to an outside collector using the UDP (native) sensors:

    • /junos/chassis/cmerror/configuration
    • /junos/chassis/cmerror/counters

    [See sensor (Junos Telemetry Interface).]

  • CoS interface telemetry support (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 supports gRPC Network Management Interface (gNMI) streaming of CoS interface queue statistics. To stream statistics, use the resource path /qos/interfaces/interface/output/queues/queue/state/.

    [See Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface)].

  • INITIAL_SYNC telemetry support (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 extends INITIAL_SYNC support for OpenConfig data model openconfig-interfaces.yang to new platforms. This feature lets the collector have a complete view of the current state of every sensor it is subscribed to. INITIAL_SYNC requires that at least one copy of all the sensors be sent to the collector. This feature has gRPC and gNMI support.

    We support these resource paths:

    /interfaces/interface/

    /interfaces/interface/ethernet

    /interface/holdtime/state

    /interfaces/interface/subinterfaces/subinterface/

    • /interfaces/interface/
    • /interfaces/interface/ethernet
    • /interface/holdtime/state
    • /interfaces/interface/subinterfaces/subinterface/

    [See Telemetry Sensor Explorer.]

  • INITIAL_SYNC telemetry support (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 extends INITIAL_SYNC support for OpenConfig data model openconfig-platform.yang and openconfig-alarms.yang to new platforms. This feature lets the collector have a complete view of the current state of every sensor it is subscribed to. INITIAL_SYNC requires that at least one copy of all the sensors be sent to the collector. This feature is supported with gRPC and gNMI.

    We support the following resource paths:

    • /components/component
    • /system/alarms/alarm

    [See Telemetry Sensor Explorer.]

  • Pause frame receive and transmit counter support (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 includes JTI support for the sensor /interfaces/interface/ethernet/state/counters/jnx-pfc-statistics to stream pause frame counters from a router and transmit them to an outside collector.

    Transport statistics using remote procedure call (gRPC), gNMI, or UDP (native).

    [See sensor (Junos Telemetry Interface) and Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface).]

  • Packet Forwarding Engine sensor support (PTX10001-36MR, PTX10004, and PTX10008)—Junos OS Evolved Release 21.4R1 has JTI support for enhanced counters in the following areas:

    • Telemetry for device monitoring
    • Hardware components that require support NPU (using the INTEGRATED_CIRCUIT type)
    • Hardware drop reason counters

    • IP-in-IP encapsulation and de-encapsulation counters

    • Forwarding table occupancy

    Transport statistics using gRPC or gNMI using the following resource paths:
    • /junos/system/linecard/packet/usage/
    • /junos/system/linecard/npu/memory/
    • /junos/system/linecard/npu/utilization/

    [See Telemetry Sensor Explorer.]

  • Packet Forwarding Engine sensor support for non-viable aggregated interface member links (PTX10008 and PTX10016)—Junos OS Evolved Release 21.4R1 has JTI support for non-viable aggregated interface member links. This feature does not support non-LAG link members. Use the resource path /interfaces/interface/state/forwarding-viable to stream statistics from a router to an outside collector by means of gRPC or gNMI.

    [See Telemetry Sensor Explorer.]

  • Platform sensors (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 includes JTI UDP streaming support for the sensors /junos/system/cmerror/configuration/ and /junos/system/cmerror/counters/.

    [See Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface).]

  • SR-TE colored policy RIB5 and SR-TE colored telemetry sensor support (PTX10008)—Junos OS Evolved Release 21.4R1 introduces JTI streaming and ON-CHANGE sensors that deliver operational state statistics for Segment Routing–Traffic Engineering (SR-TE) colored policy RIB5 and SR-TE colored telemetry sensors. Statistics are delivered to an outside collector using gRPC or gNMI. Included are new OpenConfig resource paths for existing and new SR-TE policy (tunnel) and SR-TE per-LSP colored statistics.

    [See Telemetry Sensor Explorer.]

  • SR telemetry sensor enhancements (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Junos OS Evolved Release 21.4R1 supports segment routing sensor enhancements for per SID level and interface level traffic counts. These changes comply with the current supported sensors in the OpenConfig models openconfig-segment-routing.yang and openconfig-mpls.yang.

    We've included new resource paths with the enhancements:

    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/interface-ref/state/interface [‘et-1/0/1’]
    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/interface-ref/state/subinterface [0]
