Junos Telemetry Interface

  • BGP neighbor telemetry with sharding (PTX10003 and PTX10008)—Starting in Junos OS Release 21.1R1, we support BGP neighbor telemetry with sharding (multithreading).

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

  • SPRING statistics sensor support for JTI (PTX10003)—Starting in Junos OS Evolved Release 21.1R1, JTI enables support for the export of Source Packet Routing in Networking (SPRING) statistics to an outside collector using remote procedure call (gRPC) services and gRPC Network Management Interface (gNMI) services.

    This feature provides SPRING statistics for ingress and egress per-interface and per-child member at the physical interface level.

    To enable SPRING statistics, include the following statements on the client device:

    • For egress (per-interface and per-child member at the physical interface level), use the set protocols isis source-packet-routing sensor-based-stats per-interface-per-member-link egress statement at the [edit] hierarchy level.
    • For ingress (per-interface and per-child member at the physical interface level ingress), use the set protocols isis source-packet-routing sensor-based-stats per-interface-per-member-link ingress statement at the [edit] hierarchy level.

    Use the following sensors to export statistics using gRPC or gNMI services to an outside collector:

    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/state/in-octets/ for ingress (per-interface and per-child member at the physical interface level ingress) SPRING traffic.
    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/state/in-pkts/ for ingress (per-interface and per-child member at the physical interface level ingress) SPRING traffic.
    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/state/out-octets/ for egress (per-interface and per-child member at the physical interface level egress) SPRING traffic.
    • /network-instances/network-instance/mpls/signaling-protocols/segment-routing/interfaces/interface/state/out-pkts/ for egress (per interface and per-child member at the physical interface level egress) SPRING traffic.
