Hey Ulrich, I'd say SNMP, but it depends on how you will view the data. It really depends on what you'll use to "monitor the monitor". I poll a lot of data with SNMP and it barely flinches, I even poll iptables rules and there are over 1200 of them on one system. SNMP is made to be fast and readable.
SNMP and Telnet(best for local wired connections) have a smaller footprint, that's why you generally see the two on most embedded systems(running together), such as sip phones and routers. Telnet is plain text but most SNMP data is as well, but SNMP has security mechanisms the allows the traffic to be encrypted. SSH is great but its the swiss army knife and a bit of overkill IF you want to monitor systems from a monitoring platform or a NOC. I can point at countless routers that run snmp out of the box...not many that run SSH out of the box though, even washing machines have SNMP nowadays(serious). You said every 5 minutes...but where is this data being stored or where will you retrieve it? How will you get this stuff? If you use SSH you'd have to be a pretty impressive coder to do 1/10 of what SNMP does by design. Monitoring system deltas in realtime and acting up a high or low delta, each time it happens...add 6 more systems with deltas and traps...how many fingers do you have? You can SSH in and use GNU Screen and run ton of screens with separate programs for each resource in each screen, but it gets really really messy. I do this when I need to fix a problem but it's really inefficient if you need to see several things at a glance. You can run something as small as wmnd-snmp and see all those values on your desktop or even use gkrellm with snmp and see everything your heart desires. On another note I know quite a few programs that will monitor system info in a sane way via cli and I'm sure tons of others in this LUG do as well.
