You can also use munin charts in "on-demand" cgi mode where the charts 
are being drawn only when called for from the pregenerated HTML (which 
can also be on-demand). This also enables chart zooming. You need to 
configure your webserver to run few perl scripts via cgi.

Otherwise munin-node is just a set of perl scripts and other than the 
dependency list, really is lightweight.
