The KAR browser is a graphical utility to browse through and open the historical records kept by the Kstat Activity Reporter.
The list on the left shows the avialable files, each keeping one
days worth of archival data. By default, these are found in the
/var/adm/ka directory.
Selecting a file loads it into the Kstat Browser and Kstat Chart Builder, available in tabs in the right-hand panel.
