Export Timing Data to Collectors

Junos telemetry interface (JTI) supports export of timing attributes for Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE) to the collector. Export of data is through native models (export of PTP data is through the YANG model). Both periodic streaming and on change notifications are supported. The following new subscription paths are introduced:

  • For PTP: /state/protocols/ptp/instances/instance[instance-index]/

  • For SyncE: /state/protocols/synce/

Note:
  1. Only gNMI is supported.
  2. For periodic streaming the minimum interval is "2" seconds and maximum interval is "65535" seconds.
  3. UDP streaming telemetry is not supported.

Configure Timing Data Export

To configure export of timing data, run the following extension service commands on the device:

  1. set system services extension-service request-response grpc ssl local-certificate certificate-id

  2. set system services extension-service request-response grpc ssl port 32767

  3. set system services extension-service notification allow-clients address 0.0.0.0/0

  4. Disable zero suppression, run the command set services analytics zero-suppression no-zero-suppression
