Denise is the system administrator of a Linux system. She notices that whenever a
specific process is running the performance of the system declines severely. What can
Denise do to learn exactly how the process affects her system?
A.
Use the top program to see if the program is CPU-intensive.
B.
Use performance monitor to monitor the process.
C.
Kill the process and observe the result.
D.
Use pine to check the process.
Explanation:
The TOP program will provide an interactive screen with information
similar to the ps command, and will display performance statistics.
Incorrect Answers:
B: Performance monitor is a Windows term, and is not used in Linux. Performance toolsavailable
in Linux are: ps, top, and vmstat.
C: Killing the process will lose the necessary information on how the process degradedthe system
and affected it. Denise needs to see the effect, ad this has to be done while thetask is running and
still doing its damage.
D: Pine is a mail program, and does not provide performance checking.
