問題文
A report claims that a nightly statement occasionally takes far longer than usual but it does not appear in the aggregated list at all. Which view should be used to investigate it?
選択肢
- The dashboard view because a cloned template contains a widget that lists the statements which fell outside the tracked set on that host.
- The sampled view because snapshots of running sessions are captured without regard to whether the statement ranks among the tracked top statements.
- The infrastructure view because the resource figures of the host reveal which statement was responsible for the slow period during that night.
- The aggregated view because the row for the statement appears as soon as the time frame of the page is widened to cover the whole of the night in question.
