Network Monitor

Posted on 2005-04-25

I need something that can monitor network devices. Router, Switch, and server. Something basically that can ping each device during a time peroid set by me and notify me via email if the device does not respond. I was looking at OpenView by HP but really need something less advanced.

    Nice fairly simple one is What's Up Gold by IpSwitch Software -  I use it and rather like it.

    There are other free things out there, like Big Brother, Big Sister, Nagios and i'm fairly certain there are others.  But these aren't necessarily as easy to setup as WhatsUp.  for each of the free ones, just do a google search for "Big Brother Network", "Big Sister Network", and "Nagios" and you should get tons of info including download sites.

    I have used Nagios (Nagios used to be called NetSaint) in the past and find it to be a great program. It is free so it wouldn't hurt to give it a try before shelling out money for a commercial product. If you try it and don't like it or cannot get it to run properly then you've lost nothing (well, maybe time).

    "Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser."

    Nagios is great, we used it to monitor our network at my last major position.  Problem was it took months to configure and learn (We did have a fairly large network - 30 buildings on campus, a few off, managed switches in all, more than 200 servers (running Linux/Windows/Mac oS X/Solaris).  It works off text configuration files.  What's up, though $500-$1000 if I'm not mistaken is fairly easy and quick to setup.  Well worth it in terms of time spent.

    Hi xy8088,

    I am currently learning to setup NAGIOS  which I download from  its website, and running about it's documentation,  however, I really find a problem here, if you can help up ?

    I down the tar file, and  "unizp" on my Redhat 8  ,  uding the ./configure to configure it.

    1. Run the MAKE ALL
    2. Rin the Install  staff
    3.  Install apache,  modify the httpd.conf,  
    4. Server httpd restarted as well.

    When I visit the http://<server_name>//nagios/

    cansee the nagios HTTP webpages.   However one thing I don't understand is that   in the /etc  there are a number of samples .cfg files, how I got to change them , before it can work,  I notice the hosts.cfg is not there, if I need this file, how can I create it, or whereI can get it, please advise.

    Sorry fox404 but when I used Nagios in the past I was just using it on the workstation assigned to me, I had no part in installing it or configuring it. So I don't know the answer to your question.
