An alternative (and possibly preferred ) solution is RRDTool. It is
It's by the same person (Tobi Oetiker), and is more powerful, flexible,
and quiker to run. It will log any data you give to it. From any source.
It will also generate graphs on demand, rather than all the time. All
you need to do is collect the data, and give it to RRDTool. This means
you can avoid installing SNMP, if you don't like it, or are concerned
about its security, or just don't like it.
I generate a bunch of graphs with RRDTool for each major kind of traffic
in and out of my hosted machine, disk space, cpu usage, number of emails
in and out of the machine, and number of port scans per day.
Literally, anything you can extract numbers for, it will graph. It does
mean writing your own data gathering scripts though, but that's not
hard. Just a few lines of perl will usually do.
