Real life scenario

This is a two part real world scenario question ?
It is required that we use two of the following linux based Ip monitor tools bmon, pktstat, iperf, and tcptrack

requirements: a strategy is required to effectively effectively monitor Ip traffic on an individual server as well as many servers on a point in time and as as well overtime basis. There is also a requirement to automate the alerting of potential issues based on changes in network utilization.
 We need a real world example of how you meet this requirement with the use of tools like Putty Ubuntu FileZilla, and others through scripts , alerts, output formats or scheduled tasks. ie cron jobs
