Junos Telemetry Interface

  • Telemetry stream path resolution by MPLS and RSVP interfaces (ACX710, ACX1000, ACX1100, ACX2100, ACX2200, ACX4000, ACX5448, ACX4558-D, ACX5448-M, MX150, MX204, MX340, MX480, MX960, MX2008, MX2010, MX2020, MX10003, MX10008, MX10016, vMX, PTX1000, PTX3000, PTX5000, PTX10002-60C, and PTX10008)—Starting in Junos OS Release 21.3R1, you can choose to stream telemetry statistics only for MPLS and RSVP-enabled interfaces. Use the resource path /network-instances/network-instance/mpls/signaling-protocols/rsvp-te/interface-attributes/interface/admin-status.

    [See Configuring a Junos Telemetry Interface Sensor (CLI Procedure) and Telemetry Sensor Explorer.]

  • Inline video monitoring statistics (MX240, MX480, MX960, MX2010, and MX2020 routers with MPC10 or MPC11 line cards)—Starting in Junos OS Release 21.3R1, you can use new sensors to stream video monitoring related statistics and MDI flow alarms generated to an outside collector by means of remote procedure call (gRPC) or gRPC Network Management Interface (gNMI). Statistics and alarms are provided for each configured line card. Use the resource paths /junos/system/linecard/services/vmon-mdi/ and /junos/system/linecard/services/vmon-mdi-alarm/.

    [See Telemetry Sensor Explorer.]

  • Abstracted fabric interface support (MX2010 and MX2020 with MPC11 line cards)—Starting in Junos OS Release 21.3R1, JTI sensor support is extended to MPC11 line cards for abstracted fabric interfaces. The routers support this sensor only for node virtualization configurations where an abstract fabric Interface is the connecting link between guest network functions (GNFs). The JTI sensor reports:

    • Interface-specific load-balancing and fabric queue statistics.
    • Aggregated statistics across all abstracted fabric interfaces hosted on a source Packet Forwarding Engine of local GNFs.
    • Fabric statistics for all traffic arriving from the fabric interfaces on the local GNF Packet Forwarding Engine and exiting to the fabric on that Packet Forwarding Engine.

    The MX2010 and MX2020 support the sensor through gRPC and UDP (native). Use the resource path /junos/system/linecard/node-slicing/af-fab-stats/ to configure the JTI sensor.

    To provision the sensor to export data through gRPC, use the telemetrySubcribe RPC to specify telemetry parameters.

    For UDP native export of statistics, configure parameters at the [edit services analytics] hierarchy level.
