I need to monitor the performance of an Ubuntu 12.04 machine. I am looking for a tool similar to PerfMon on Windows.

I need something more interactive that using top from a terminal ; I am looking for something both interactive and GUI-based.

Does anyone have suggestions?

You should probably enumerate the features from perfmon on windows that you like (especially as Ubuntu people are less likely to have used windows software). BTW, htop is a worthwhile (still CLI) improvement top. – belacqua Mar 24 '14 at 17:32

You can use the default System Monitor. Launch it from terminal with gnome-system-monitor or search for System Monitor/Task Manager on the search window in the sidebar. If you prefer to use terminal based system monitor, try htop or nmon

what is the location to access the default system monitor , are you talking about typing top in terminal I am interested in GUI based tool – tushar_sappal Mar 21 '14 at 16:49
It's GUI based. It's like Windows Task Manager. Type gnome-system-monitor on the terminal. – Giammarco Boscaro Mar 21 '14 at 16:51
Can i access the default performance monitor from the global search – tushar_sappal Mar 21 '14 at 16:53
Yeah you can, search Task Manager (or System Monitor) – Giammarco Boscaro Mar 21 '14 at 16:54
thanks i will try – tushar_sappal Mar 21 '14 at 16:55

run top in terminal.

There are other flavors or top as well but they need to be downloaded.

i saw top today when i typed top on terminal , basically it just lists the processes and their cpu usage in a tabular form I am looking for more interactive way to view performance – tushar_sappal Mar 24 '14 at 16:45

A particular flavor of top that we use here is htop. Still CLI based but much more 'graphical'.

Install it with:

sudo apt-get install htop
