As part of a performance tuning exercise, a decision needs to be made of whether to implement
real-time monitoring or logged monitoring. for an already severely resource-constrained system,
which system impact is important to consider prior to making a decision?

A.
There is no difference in system impact between logged and real-time monitoring.

B.
Real-time monitoring is more costly in CPU time and must be accounted for in performance
reports.

C.
Logged monitoring is more costly in CPU time and used for analysis at a later time.

D.
Both methods result in large log files that may fill file systems.
