A municipal library consortium enables on-change model-driven telemetry but must keep collector and WAN volume manageable. Which subscription practice helps most?
Select an answer to reveal the explanation.
Short Explanation
On-change for every leaf on every port is a firehose aimed at a drinking fountain. Narrow the subscription to the uplinks and critical interfaces you actually page on. Filtering is how the library keeps the collector standing.
Full Explanation
Telemetry scale is controlled largely by what you subscribe to: path filters, sensor groups, and on-change versus sample policies. Limiting on-change streams to critical interfaces reduces event volume and collector load. Unfiltered everything-subscription and packet mirrors are not efficient substitutes for YANG path filtering.
