問題文
A database team fronts every instance with a connection pooler so that clients share a small number of sessions. Where should the Agent be pointed when Database Monitoring is enabled?
選択肢
- At the pooler itself because statistics are aggregated there and a shared front end already merges the counters from the hosts that sit behind it.
- At the pooler itself because sessions are reused there and a shared front end keeps the number of monitoring connections low.
- At the instance itself because statistics are read as differences over time and a shared front end can move the reader between hosts.
- At the load balancer itself because health checks run there and a shared front end knows which host is currently the writer.
