I have sysstats already but want a graphing. ksar sounds appealing. I do not have physical access to this server so I need to access ksar through http on the server. Does it support that? Googling for the answer on how to do this but not finding what I want yet.
No, kSar is a desktop app and is IMO a PITA to use - I keep it in my pocket only when I need very fine granularity.
Most of the other ones mentioned have web front ends - Munin being the one I went with but I evaluated most of the other ones mentioned.
