4.6. Performance monitoring
Monitoring allows you to get more out of your operating system by helping you determine the types of applications and their behavior in the system. TLinux bundles a good monitoring tool natively within the operating system. A good starting point is to use standard tools such as ps, top, vmstat, sar and iostat. These applications are easy to use and provide administrators with a quick glance at system performance.
In addition, you can also use bundled tools like ksysguard, which can consolidate multiple systems and display it in a single window. Figure 4-11 on page 193 shows multiple LPARs that were added to the ksysguard window. It shows the average load of all the servers.
