Junos Telemetry

  • Enhance VLAN/MAC statistics support for streaming telemetry (EX4300-MP, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48MXP, EX4400-48XP, EX4400-48P, EX4400-48T, EX4650, EX4650-48Y-VC, EX9204, EX9208, EX9214, QFX5120-48Y, QFX5120-48Y-VC)You can enhance the granularity of streaming telemetry by subscribing to specific xpaths of leaf nodes using Yang state models generated from ODL files. This subscription-based model provides precise and efficient data collection compared to the traditional RPC mechanism. Note that this solution supports only periodic streaming of telemetry data.

    For more information, see Junos YANG Data Model Explorer.

  • Stream telemetry data in gNMI-based message format over UDP (MX204, MX240, MX301, MX304, MX480, MX960, MX10003, MX10004, MX10008, MX10016, MX2008, MX2010, MX2020, QFX5100VC, QFX5110, QFX5110-VC, QFX5110-VCF, QFX5120-32C, QFX5120-48T, QFX5120-48T-VC, QFX5120-48Y, QFX5120-48Y-VC, QFX5120-48YM, QFX5200, and QFX5210)—Junos OS uses a dial-out mechanism to send telemetry data to a collector over UDP. The message format is defined in the jnx_gnmi_over_udp.proto file. This mechanism supports only STREAM mode with SAMPLE as subscription mode. The message contains full key name and value pair information so the collector does not require data models for processing or consuming the telemetry data.
