Is there a good reason why it´s default to 5 min.? Obviously, graphs like cpu load etc. do not display accurate information within 5 min polling span and thus do not reflect the actual load of the cpu. Implementing a (future) alerting system is useless with this kind of data.
You're quite fundamentally wrong here.
Especially with something like CPU load, you're only really interested in the load averaged over time. Every single thing the CPU ever does will push the CPU load to 100% for some period of time.
I would expect most people not to even care about a single 5-minute spike in load, but rather to delay alerting on CPU load for a greater number of polling cycles.
5 minutes is a somewhat industry standard polling cycle which gives a good-for-most-people trade off between resource requirements and resolution of data.
