To run a "collectd" server you basically need to have minimum 2
plugins configured. a) network b) rrdtool. On "server" you need to
have both "network" as well as "rrdtool" plugins configured, whereas
on "clients" you just need to have "network" plugin pointing to
"server". Also make sure that your clients are able to resolve
"monitor1.company.net" ip.
