Let's say we have vMX using segment routig with North Start controller. On vMX, we are using sensors for physical interface, logical interface and LSP, the stats( interface delay, LSP delay, BW utilization) are sent to North Star collector. Using these stats, North star can make intelligent decsion to optimize LSP.
I have some questions:
1) How does vMX, using Sensor, determine interface delay stats ( which is then sent to North Star controller)?
