title: mongoimport: how to monitor execution time?
body: <p>I'm running MongoDB on Ubuntu 14.04.</p>
  
  <p>I'm successfully importing data from CSV into MongoDB, but I want to be able to get a reading of the total execution time for the operation.</p>
  
  <p>I've been using the .explain() command to monitor query CRUD operations executed within mongodb.exe itself, but this obviously won't work on the import process which is executed from the bin level.</p>
  
  <p>Please can anyone advise how I can easily get a performance reading for the import? (i've had a cast around and can't find any suitable guidance).</p>
  
  <p>The code I'm using for the import is:</p>
  
  <pre><code> jon@ubuntu:~/Desktop/mongodb-linux-x86_64-2.6.3/bin$ mongoimport --db jontestcsv --collection Aircraft --ignoreBlanks --type csv --headerline --file /home/jon/Desktop/Aircraft.csv
  </code></pre>
  
  <p>Greatly appreciate any guidance.</p>
  
  <p>Regards,
  Jon</p>
