Most of linux sysadmins are famillar with sar, a tool to collect several system performance data in an unix/linux system.
Less know is kSar, a tool written in java to visualize data from sar. Last version is from 2013 but still very useful.
Because the tool unfortunately not available in Fedora 25, i have created a rpm- package for my own.
rpm: kSar-5.0.6-1.1.x86_64.rpm
src-rpm: kSar-5.0.6-1.1.src.rpm
repo: kSar.repo
