Export of data associated with the Junos kernel through Junos Telemetry Interface (JTI)

You can export data associated with the Junos kernel through remote procedure calls (gRPC) and JTI. Kernel telemetry data includes information on Veriexec state, graceful Routing Engine switchover (GRES), in-service software upgrade (ISSU), and Routing Engine ifstate. 

Junos kernel sensors can be used by device monitoring and network analytics applications to provide insight into the health status of the Junos kernel. Junos kernel sensors supports both periodical and ON_CHANGE streaming. The following Junos kernel resource paths support periodical streaming only: 

• /junos/kernel-ifstate/dead-ifstates-cnt 
• /junos/kernel-ifstate/alive-ifstates-cnt 
• /junos/kernel-ifstate/delayed-unrefs-cnt 
• /junos/kernel-ifstate/delayed-unrefs-max
