How to find out what process is using CPU to what extent in Ubuntu? I'd like to have real-time data as well as recorded history. Both console and GUI apps would be great.
The situation is that my system seems to be really overloaded right now and I don't know why for sure. I've spent some time killing processes and watching if performance improves. And I suspect that JS Scripts running in Mozilla are causing problems. All in all a nice tool for taking a look at CPU usage would come in handy.
I have used hprof before which bundled together with JRE. It does HEAP and CPU monitoring. I usually use it to monitor CPU usage and check which thread is taking majority of CPU. http://java.sun.com/developer/technicalArticles/Programming/HPROF.html
I also used JProbe before which is a commercial software. http://www.quest.com/jprobe/
I'd recommend Observium if you want a pretty web-based display of system information. It covers most of the attributes you wish to track and works well in single-server installs as well as multiple system deployments. Take 20 minutes to set it up and give it a try. There's also a live demo available.
If you need realtime data in a text user interface, look at collectl.
Edit:
Today, I recommend Netdata.
