The Configuration required to stream segment routing traffic engineering usage stats.
Telemetry output will not have any leafs sent even though subscribed to the path /junos/services/segment-routing/traffic-engineering/ingress/usage.
show agent sensors will report the sensor as installed.
To receive the telemetry stats for the path /junos/services/segment-routing/traffic-engineering/ingress/usage, there is a minimum config required as below:
set protocols source-packet-routing telemetry statistics [edit protocols] + source-packet-routing { + telemetry { + statistics; + } + }
<-- The above config enables the protocol level stats collection.
<-- However, if actual traffic stats required for the subscribed path /junos/services/segment-routing/traffic-engineering/ingress/usage, additional config is required to pull the stats from the PFE.
<-- From show agent sensors output without the additional config:
