질문 # 107
What does the totalCreated field mean in the output of the db.serverStatus().connections command?
> db.serverStatus().connections
{
" current " : 4,
" available " : 51196,
" totalCreated " : 5,
" active " : 2,
" threaded " : 4,
" exhaustIsMaster " : 1,
" exhaustHello " : 0,
" awaitingTopologyChanges " : 1
}

  • A. The number of connections since the server was started.
  • B. The number of connections since the server was set up.
  • C. The total number of database connections at the moment.
  • D. The number of closed connections in the server ' s history.

정답：A

설명：
connections.totalCreated is a cumulative count of incoming connections created during the lifetime of the running MongoDB server process. It includes connections that are still open as well as connections that have already closed. That is why the example can show totalCreated: 5 while current: 4: five connections have been created since the process started, but only four remain current. Option A is incorrect because the counter is not limited to closed connections. Option C corresponds more closely to connections.current, which reports presently existing incoming client connections. Option B is imprecise because "since the server was set up" could imply the lifetime of the installation or deployment across restarts, whereas server-status counters generally reflect the current process lifetime. Tracking totalCreated alongside current, active, and connection- pool behavior helps administrators identify excessive connection churn, poorly configured client pools, or bursts of new connections. The most accurate interpretation among the choices is therefore the number of connections created since the server process was started, making D correct.
