問題文
A hosting provider wants application metrics to survive the loss of a cloud proxy. What does moving the existing agents onto a collector group with high availability cost?
選択肢
- The agents have to be installed again against that collector group, and the application data gathered before the move is lost when the proxy joins the group.
- The agents keep working as they are and the group takes over on its own, because the change is made on the side of the cloud proxies and the target machines are not aware of it at all.
- The agents have to be uninstalled and the past metrics are moved into the new group, because the platform carries the history across when it rebalances.
- The agents have to be pointed at a virtual address by hand, because a group with high availability does not publish an address of its own.
