* Monitoring to identify the nature and scope of the resource shortages that are causing the performance problems.
* The data produced from monitoring is analyzed and a course of action (normally performance tuning and/or the procurement of additional hardware) is taken to resolve the problem.
* Monitoring to ensure that the performance problem has been resolved.
You can monitor your OpenSuSe system in one of the following fast and easy ways.
System Monitor is a default installed utility to monitor the system. It can be loaded from
Applications → System → Monitor → System Monitor.
It has a very groovy graphical interface with two main tabs, Process Table and System Load.
Process Table shows the CPU, memory, and network performance in the form of graphs. Have a look at the following screen shot.
Now, go to the System Load tab, it will show you all running programs along with their memory usage. From here you can get an idea which program is consuming more resources of your system and for here you can even kill or change the priority of the process (Rt click on the process and check all those things that you can do to a selected process).
