Monitoring the performance of the network

Posted on 2006-05-31
Last Modified: 2013-12-07

We are a school with 250+ nodes with 2 servers running server 2003.

Currently we are experiencing network slowdowns at various times, and general slowness when students login - with errors that their profiles can not be found etc.

Is there any way that we can monitor the network to locate where a problem might lie? Ideally we would like something simple that is easily administered, perhaps with an application on student pc's that would send information to a test PC rather than our servers.

Many thanks in advance.

    If you can afford it, SolarWinds Orion is an EXCELLENT tool for this, it would probably be around 3-4K for an installation your size.

    What kind of network gear are you running?  Manageable switches?  Dumb hubs?

    Can you describe your infrastructure better?

    What about the Domain Controller(s) - any errors in the logs?

    Thanks for the reply psuedocyber :)

    The solarwinds solution does look appealing but we cant justify the cost, sadly :(

    We have 3 Domain Controllers running 1 domain, an Exchange 2003 server, Print server, backup server, proxy server and caching server.

    The network manager has managed to solve errors in the logs but we still seem to suffer from network slowdowns. Please excuse my lack of description regarding the infrastructure but I have only recently joined the school and still learning things myself.

    Is there any other (cheaper) option to locate where network latency may be occuring?

    Well, you could get ethereal and do some packet analysis and compare that to a known good baseline of past performance.  And you can go into your switches and routers and manually analyze and chart performance data from interfaces.  All of that takes a lot of time and requires expertise analyze the data.

    You can google "open source network monitoring" and spend a lot of time learning those programs and installing them into some form of Linux box.

    Remember this phrase, "You can have it good, cheap, or fast - pick 2".

    good + cheap = slow
    good + fast = expensive
    cheap + fast = bad
