title: How to get csv data used to create graphs in Jconsole
body: <p>newbie here.
  I have a java application and I am working on to monitor that java application. I come to know about the java monitoring and management control using 'JConsole'. It giving a very detailed graphical information about the running java process. </p>
  
  <p>but the thing I am wondering is about the data used to generate the graphs. As in JConsole we can save the data in csv format by right clicking on running graph, Is there any command line option to get the data only in csv format.</p>
