I can't use it
I already knew the Sample Frequency I need, and I can't use it. Almost nobody in telcos can.
Reasons: it would bring to a halt all the systems.
So we are stuck with "good enough" and "hope for the best". We have also better approaches: a mix between data polling and SNMP traps (alerts).
Anyway, I think that what people need is top down alerts AND checks. so you just klnow the health of the system, you aren't really interested in components.
