    Re: Network Monitor

    Hi Cosy,

    If you have some money to spend, the absolute best solution, in my opinion, is packeteer.

    If you are trying to do this on a shoestring budget. Here are some products:
    • In this thread, brian desmond recommened some open source products called Cacti and Nagios
    • I have used MRTG and PRTG successfully although these will monitor and graph performance over time but not necessarily tell you who is using that bandwidth unless you add Netflow to PRTG
    • I have also used Observer, but this is also a commercial solution. Observer is more of a protocol analyzer.


    Does anyone else have any good solutions?

    Thanks for your post!

        Hi Cosy,

        A simple solution that is free might be to just put Ethereal on the segment. It has some basic charts and graphs but it can then dig all the way down to who is doing what and even show you the bits.

        If you haven't used a protocol analyzer before, it might take some getting used to but it will be a tool that, as a network admin, you will probably use off and on, throughout your career (I know I have).

        You can find it at:
        www.ethereal.com

        I hope that helps out

        Thanks,

            Hi Cosy,

            Although I haven't yet had the pleasure of using it myself, I have been told my many that Nagios is an excellent free enterprise-grade network monitoring system.

            I did read in the documentation that it does support email and SMS. Here is what it says:

            There are many ways you could configure Nagios to send notifications out. Its up to you to decide which method(s) you want to use. Once you do that you'll have to install any necessary software and configure notification commands in your config files before you can use them. Here are just a few possible notification methods:


            Email
            Pager
            Phone (SMS)
            WinPopup message
            Yahoo, ICQ, or MSN instant message
            Audio alerts
            etc...
            Here is the link to the notifications:
            http://nagios.sourceforge.net/docs/3...fications.html

            You can download it at:
            http://nagios.org/download/

            Or there are a number of fully functioning VMware Nagios appliances you can download at:
            http://search.vmware.com/search?q=na...vmtn_appliance

            Let us know how it goes!

            Thanks
