I've set up Cacti on my web server and it gives me graphs for Load Average and Memory Usage and such but I'd also like to monitor how much bandwidth my site is using.
I've been reading some of the Cacti documentation and I tried searching with Google but I can't seem to find anything that explains to me how to do this.
Could it be that I shouldn't be looking at Apache for bandwidth measurement but at a lower level device? I'm currently running my LAMP stack on a EC2 instance if that makes a difference.
Since asking this question I've actually switched from Cacti to Munin. Not that one is better than the other but simply because Munin suited more with my needs since out of the box it showed me everything I needed to know. I might still use Cacti in the future though.
