Is there a better sar(1) grapher than isag(1)?

I'm using sar to collect cpu+i/o+memory usage of some servers.

I want to view these statistics graphically. The only program I've found that does this is isag, but it's unsatisfactory for these reasons:

• primarily
  • isag requires data files to be present on the local machine; I want it to be able to ssh into my servers and run sar there
• but also
  • the graphs are ugly
  • the gui is ugly
  • isag is unfriendly

Is there a better alternative to isag (on my primary point at least)?

Or, is there an alternative to sar for which there is a better graphing tool?

Thanks.
