Junos Telemetry Interface

  • System health reporting sensors over gRPC (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016 routers and QFX5130-32CD and QFX5220 switches)—Starting in Junos OS Evolved Release 22.4R1, Junos telemetry interface (JTI) supports data model openconfig-system.yang using gRPC remote procedure calls (gRPC) and provides new health-monitoring sensors.

    [See Telemetry Sensor Explorer.]

  • Support for gRPC tunnel sessions (PTX10001-36MR, PTX10003, PTX10004, PTX10008, PTX10016, QFX5130-32CD, and QFX5220)—Starting with Junos OS Evolved Release 22.4R1, you can configure a gRPC remote procedure call (gRPC) tunnel session to establish a connection between an external TCP client and a TCP server. The gRPC tunnel session establishes a reverse connection when a TCP client can't reach the TCP server.

    To establish a gRPC tunnel session, include the grpc-tunnel configuration statement in the [edit system services] hierarchy.

    [See gRPC Tunnels Overview.]

  • Telemetry for IPv4/IPv6 traffic statistics (QFX5220)—Junos OS Evolved Release 22.4R1 introduces support for streaming IPv4 and IPv6 transit statistics using resource path /junos/system/linecard/interface/traffic. The following fields will be exported:

    • if_in_ipv4pkts

    • if_out_ipv4pkts

    • if_in_ipv6pkts

    • if_out_ipv6pkts

    To enable IPv6 transit statistics for the physical port, you must configure IPv6 route accounting.

    Support for OpenConfig is available under resource path /interfaces/interface/.
