Network Link monitor.

[Webb, Nathan]

I haven't done this before, so I'd be interested in any feedback, but I
would have thought that you could have used Nagios for this.



If you want to collect latency and bandwidth information, then you could
use any number of tools for this, such as my personal favourite,
cricket.  Smokeping looks pretty good for latency, but then again you
could just use Nagios with one of the many perf data graphing add-ons.



Once you are collecting that information, the next step is to be able to
visualise this with a bird's eye view.  This is what Nagios does for us,
so you could use passive checks to warn you when a bandwidth threshold
is exceeded.  Latency would be easy enough to do within Nagios with the
check_icmp plugin.



Finally, just display the list of host problems to give the bird's eye
view.  If there's nothing there, then everything's good!

All,



I'm sorry this post is outside the general scope of this mailing list,
but I'm trying to get information from the group that would most likely
be try to accomplish the same things.



My company is in the process of building a new datacenter and ownership
wants to setup a NOC.  I know that in addition to my Nagios server
keeping me informed on what is going on inside my environment, it shows
very well, great in fact.  What I am trying to find is a complimentary
app that will monitor my links between remote locations and our
datacenter.



I have an nTop (http://www.ntop.org <http://www.ntop.org/> ) Server
located at my datacenter and it collects a lot of great information, but
it's almost too detailed and in a format that show terrible.  I'm
looking for something that gives a bird's eye view of my network and its
links.  I'm mostly interested in ICMP response time presented in a
graphical format and bandwidth utilization. 



Here is an example of what I was hoping to find:

The screen shot is in Re: to active directory, but it has the general
'look' I'm trying to find.



Any advice would be GREATLY appreciated.



Thanks,



Kyle
