Which mongodb tool is used to report details on number of database operations in MongoDB?

Question

Options

• Amongostat
• Bmongotop
• Cmongorestore
• Dmongodump

• A
  90% (19)
• B
  5% (1)
• D
  5% (1)

Explanation

mongostat is correct because it provides real-time statistics on MongoDB server operations, reporting metrics like inserts, queries, updates, deletes, and getmores per second - exactly "details on the number of database operations."

Why the others are wrong:

• mongotop tracks time spent reading/writing data per collection, not operation counts - it's about time, not operation throughput.
• mongorestore is a data recovery tool that restores BSON dumps back into a database - purely administrative, not monitoring.
• mongodump exports database data to BSON files for backup - again, a backup utility with no reporting function.

Memory tip: Think of mongostat like the Unix vmstat command - the "stat" suffix means statistics, and it streams live operation counts just like vmstat streams system stats. If you remember "stat = statistics = numbers per second," you'll always pick the right tool.
