Question 2 -- 1.0 marks -- Could the interface monitor and network monitor all be contained within one process, if so how?
Question 3 -- 1.0 marks -- Could the interface monitor and network monitor all be contained within one process, assuming 128 network interfaces running at several Giga-bits per second, which require a polling interval of one millisecond per interface.

Question 4 -- 1.0 marks -- Generally, what are syslog and rsyslog? Specifically, name three features of syslog/rsyslog and compare them to your embedded debug logging. Will there be any overlap of information?

Question 6 -- 0.5 marks -- Name five ways syslog-ng is an improvement over syslog/rsyslog.
Question 7 -- 1.0 marks -- Consider a Log Server that has to manage embedded logs for a massive amount of processes on a massive amount of machines. Name three ways the server could manage the connections to each process.
Question 8 -- 1.0 marks -- Consider a Log Server that has to manage embedded logs for a massive amount of processes on a massive amount of machines. With such a large amount of data in the logs, name three ways a user could extract useful information from them (be general).
