round robin databases work well for this sort of data. They
progressively drop data off the end, yet still manage to keep enough
stats to continue to do nice graphs :-)
an example is mrtg, which has been taken over by a more generic but
similarly setup package called RRDTool

I was going to suggest the same as Nick, but this post put paid to that.
However, starting up using either init.d scripts *or* crontab scripts is
good. I know it sounds a bit strange, but if you put it in cron, then it

most distros have a startup script called /etc/init.d/local which fires
up on startup. however if the process dies this will not work without
further effort.
you could run the program out of inittab, a line like this will cause
the program to be restarted if it dies:
