SR-TE statistics for uncolored SR-TE policies streaming support on JTI

Junos OS provides Segment Routing Traffic Engineering (SR-TE) per Label Switched Path (LSP) route statistics using Junos telemetry interface (JTI) and remote procedure call (gRPC) services. Using JTI and gRPC services, you can stream SR-TE telemetry statistics for uncolored SR-TE policies statistics to an outside collector.

Ingress statistics include statistics for all traffic steered by means of an SR-TE LSP. Transit statistics include statistics for traffic to the Binding-SID (BSID) of the SR-TE policy.

To enable these statistics, include the per-source per-segment-list statement at the [edit protocols source-packet-routing telemetry statistics] hierarchy level.

If you issue the set protocols source-packet-routing telemetry statistics no-ingress command, ingress sensors are not created.

If you issue the set protocols source-packet-routing telemetry statistics no-transit command, transit sensors are not created. Otherwise, if BSID is configured for a tunnel, transit statistics are created.

The following resource paths (sensors) are supported:

• /junos/services/segment-routing/traffic-engineering/tunnel/lsp/ingress/usage/
• /junos/services/segment-routing/traffic-engineering/tunnel/lsp/transit/usage/

To provision the sensor to export data through gRPC services, use the telemetrySubscribe RPC. Streaming telemetry data through gRPC or gNMI also requires the OpenConfig for Junos OS module.
