I'd like to be able to customize the data collection and/or reporting to get a business hours (8-5) usage graph and a weekly 95%ile usage graph.  Are there any suggestions?  I've done very little PERL work before, but can usually manage my way through scripts.  Any help would be appreciated.

An excellent 95th percentile package is available from

As far as business hours, I'm not sure what you're trying to do.  If you're
calling MRTG from cron, you can edit the crontab to only run it during
business hours.  You'll probably want the unknown-as-zero switch set in
your config file.

IMHO, the business hours idea doesn't seem like a good one for most people.
DOS attacks, viruses, etc. often occur and cause unusual traffic patterns
at all hours.  Generally, it's good to know about such things.  Perhaps RRD
can generate the daily graph with specified begin and end times?
