Junos Telemetry Interface (JTI)
Packet Forwarding Engine performance sensors (EX4650, QFX5110, QFX5120-48Y, QFX5200, and QFX5210)—Starting in Junos OS Release 21.4R1, JTI streams NPU utilization statistics by means of remote procedure calls (gRPC), gRPC network management interface (gNMI), or UDP (native) transport from a device to an outside collector.
[See sensor (Junos Telemetry Interface), Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface), and Telemetry Sensor Explorer.]
