OK use utilities unless you can't, in which case you go to 
snmp.

I work on the Linux Virtual Server (LVS) project. Someone 
has wrote an snmp agent for LVS to monitor what is easily 
monitored by other people with the standard setup and admin 
tools (which read /proc). I haven't looked at how it works; 
perhaps it calls the admin utils underneath and returns snmp 
messages. Why might they have done that? snmp only shop? 
they like snmp? they have nothing better to do with their 
time?

I run rrdtool now which I'm happy with.
