More Information:

Packet Forwarding Engine statistics export using gNMI and JTI

You can stream Packet Forwarding Engine statistics to an outside collector using gRPC Management Interface (gNMI) version 0.7.0 and Junos telemetry interface (JTI). Prior to this, these statistics were exported using OpenConfig gRPC and UDP protocol buffer (gpb) format. OpenConfig gRPC and gNMI are both protocols used to modify and retrieve configurations as well as export telemetry streams from a device in order to manage and monitor it. To provision Packet Forwarding Engine sensors to export data through gNMI, use the Subscribe RPC defined in the gnmi.proto to specify request parameters. This RPC already supports Routing Engine statistics to be exported by means of gNMI. Now, Packet Forwarding Engine sensors will also stream KV pairs in gNMI format for a majority of Packet Forwarding Engine sensors. Streaming telemetry data through gNMI also requires the OpenConfig for Junos OS module. OpenConfig and Network Agent packages are bundled into the Junos OS image by default. Both packages support JTI.
