問題文
An organization runs Collectors on each application host and is considering adding one more Collector that receives data from all of them and forwards it onward. What does this additional layer accomplish that per-host Collectors alone cannot?
選択肢
- It converts the metric type of incoming data points so that counters become gauges, which makes the values easier to average across hosts and across longer time windows.
- It consolidates the outbound path, so a larger buffer and longer retry intervals can be configured in one place and the number of egress points and the number of tokens to manage are both reduced.
- It replaces the need for a Collector on each host, because the forwarding layer can reach into each host over the network and read the host metrics directly without anything installed there.
- It removes the need for an access token entirely; the forwarding tier presents the realm name alone when it opens the outbound session for the fleet.
