Operation not permitted

[Google Code Exporter]

I ran jvmtop.sh on an ec2 instance which is hosting a tomcat web application. 
When I ran the sh, i do not get jvm metrics related to the web application. I 
only get the metrics related to m.jvmtop.JVMTOP. 

When i try to run the jvmtop.sh with a pid for tomcat, i get the following 
exception.

What steps will reproduce the problem?
1. jvmtop.sh <pid>
2.
3.

What is the expected output? What do you see instead?
