In mongodb.log I see

I wish to see this in mongo shell. I also wish to see which index.

I googled and found

db.currentOp(
    {
      $or: [
        { op: "query", "query.createIndexes": { $exists: true } },
        { op: "insert", ns: /\.system\.indexes\b/ }
      ]
    }
)

But this query gives only

{ "inprog" : [ ], "ok" : 1 }

I wish to see all details.

I have noticed the same thing in last week. Sometimes, the mongo shell returns any empty array:

  1. Try running the currentOp() many times to get the progress.
  2. Use use db command and then perform db.currentOp()
