Junos Telemetry

  • Export packet capture statistics to external collectors using Junos Telemetry (QFX5130-32CD, QFX5130E-32CD, QFX5130-48C, QFX5230-64CD, QFX5240-64OD, QFX5240-64QD, and QFX5700)—The packet capture feature records the first configured number of host-bound packets on each physical interface and exports them to an external collector over the Junos Telemetry infrastructure. You can use this data to debug and fix network or performance issues. Subscribe to the packet-capture sensor at /junos/system/linecard/packet-capture. The device captures 50 ingress packets when an interface transitions from the DOWN state to the UP state. The data is encoded in Google protocol buffer (GPB) format and streamed over gRPC with SSL encryption. To enable packet capture, configure edit system packet-forwarding-options packet-capture packet-capture-enable .

    Use the show agent sensors command to view the packet capture sensor information.
