CPU and Network stats (and memory) come from SNMP
Space used will only return figures now if the specified directory is a mountpoint.  If this is not a mountpoint on your system then it will always return zero.

The default snmpd shouldn't need much/any config (I need to produse a quickstart note for that I think) - ensure that it is net-snmp or ucd-snmp, start snmpd and set Use SNMP=yes in the mailscanner-mrtg.conf.  You also need to ensure you have net-snmp-utils or ucd-snmp-utils installed.

If you have net-snmp then there are still a few problems with net-snmp support - I'm rolling all the patches together and will hopefully release an update tonight.

Note that you won't see changes immediately (wait say 10-15 minutes) as it works on the difference between consequtive runs

Probably not, the previous iptraffic stats were essentially meaningless (due to being a snapshot of 5 seconds of activity, rather than an average over 5 minutes).  The CPU utilization wasn't much better (and tended to be skewed by the load of mailscanner-mrtg itself).  The two disk space graphs (in your case) were showing the space of directories other that what they said they were.  So the only useful graph you have lost is memory (assuming that was working on your box & accurate - which was not the case on all OS's).

Hopefully tonight I'll get a fully-working-with-net-snmp version out the door and I'll try and do some notes on getting snmp working.

If you do downgrade there are a couple of things you need to do...

Immediately after downgrading
mv /var/www/html/mailscanner-mrtg/loadavg.log.xxxxxxxxx /var/www/html/mailscanner-mrtg/loadavg/loadavg.log

mv /var/www/html/mailscanner-mrtg/mailbytes/mailbytes.log.xxxxxxxxx /var/www/html/mailscanner-mrtg/mailbytes/mailbytes.log

(where xxxxxxx is a string on numbers  [unix timestamp])
