問題文

Users report that saving a record hangs for a few seconds during the busiest hour while the counters of the host stay flat. Which tab of the host details panel is the right place to start?

選択肢

  1. The tab for calling services because it lists the upstream callers so the owner of the affected request can be contacted about that hour.
  2. The tab for configuration because it lists the parameters of the engine so a misconfigured value can be spotted for that hour.
  3. The tab for blocking activity because it charts how long the blockers ran and how many statements were left waiting behind them at that time.
  4. The tab for the schema because it lists the tables and their indexes so the design of the affected table can be reviewed for that hour.
