Monitoring and reducing High CPU usage percentage

Question

Good Morning. Currently I am running a Java web application in Ubuntu server 11.10. For my Java application, I am using apache, tomcat and mysql.

For past few weeks, the CPU usage percentage of my production server is very high. It almost reaches to the maximum level of 100%.

I confirmed through my Amazon Web Console that, my CPU percentage is keep on increasing and decreasing. I have also checked through webmin (installed in my Ubuntu server) and confirmed that CPU usage has 100% user.

I have installed Java melody to monitor my Java application and found that there was no issues with Java or tomcat memory.

Can anyone please suggest me the reason for such high CPU usage percentage and the solutions to monitor and minimize them (or keep in control).

Thank You.
