I found this bijk, is free only for one server. Is a commercial solution and you can use it with a lot of Linux distributions (and of course with Ubuntu). |

There are a lot of monitoring solutions out there. Munin might be an option for your needs, take a look at sysstat and use kSar to visualize the results. Your choice depends on the needs you have. |

My personal tool of choice is wireshark. It has a nice gui, flexible filters, and a some analysing tools. sudo apt-get install wireshark |

karthick87 has the answer, but just to amplify it your monitoring has to be distributed amongst the 300 end-stations and cannot be simply centralized to one point. The biggest reason this is necessary is that you are probably using a switched (not shared) network hub so no single point is capable of seeing all the traffic on the net. SNMP is certainly old-school, partly because it works. |
