問題文
An engineer finds a sampled execution of a slow statement but the graphs of executions and duration on that sample page are empty. What is the most likely reason?
選択肢
- The statement was captured before the retention window opened so the aggregated metrics were removed and the graphs lost their data.
- The statement stayed outside the tracked top statements so aggregated metrics are missing for it and the graphs have nothing to draw.
- The statement ran on a host whose agent was still starting up so the aggregated metrics were skipped and the graphs stayed blank.
- The statement was issued by a client whose driver hides the text so the aggregated metrics were dropped and the graphs remained empty.
