title: How can we monitor mongoDB queries?
body: <p>I just wanted to know if there is a possible way to monitor mongoDB queries.
  I tried with the explain functionality provided by the mongo shell. But it is very hectic to manually track each and every query. 
  I am using mongoose as an ODM.</p>
  
  <p>The one which I tried is:</p>
  
  <pre><code>db.customer.find({},{name:1, active:1}).explain()
  </code></pre>
  
  <p>I got an object with the query plan, time taken and many more things. </p>
