This Article explain about the Telemetry support for the curr_buffer occupancy sensor data in EX and QFX devices.
Customers can face issue while subscribing to the path /junos/system/linecard/interface/traffic/ from the collector and can notice Zero data received by the collector for this particular path.
Based on lab to test the path related to cur_buffer_occupancy in QFX and confirmed that the buffer occupancy sensors are not supported on QFX. Please find the below output collected from the collector to see the only supported sensors when using /junos/system/linecard/interface/traffic/ path.

As per the pathfinder, these are the sensors the telemetry on QFX will support.

The curr_buffer occupancy is supported only on few juniper devices and please find the same info same.
