last brief post was about NOC , lets call again the duty of NOC is to solve users incidents as much as they can .. off loading the back end support ..so speed is required also pin point the root cause A.S.A.P … so the answer is they need Good Performance and Fault Monitor …
the P.M/FM must be designed well and cover all network parts from network to application .
i like networking parts so a good solution will be
small – meduim ; solar winds
medium – large ; EMC smart or HP or IBM Netcool
Large ; Prognosis
from experience the worse is Netboss hard to implement very costly
