Network Unix system monitoring
Hi,
I am relatively new to Unix. Today I have attended an interview and they asked me below questions
(a)How do you monitor Unix system?
(b)How do you know every thing is working fine?
(c)How do you know if there are any bottle necks?
(d)How do you know if any process is hanging and draining the resources?
(e)If the application is driven by exchange feeds, how do you know if the feeds are all set up correctly?
(f)Are you aware of any performance monitoring tools?

This is with respect to their application which is a trade processing application.

Please help me improve my knowledge.

Regards
