Network Monitoring

Hi there,

This is a slighly of the topic post, but has a relation to perl. My
company is looking for a network monitoring system with functionality that
allows us to see that all connections to our servers are up and running
and to keep track of the kb/s and response time.

Yes, this sounds like MRTG/Big Brother. We are looking for something
slightly more basic and easier to implement. Is there any open source
project available in perl that can do this for us. And also needs to be
easily extendable. Or basic unix commands that will give us this
information would also be appreciated(kb/s, response time, connections to
servers).

Yet again, sorry for the off the topic post!

Someone already suggested ntop on Perl Beginners. If you want something
that does what your asking in a CGI environment, I would start by taking
a look at rrdtool's homepage. There are quite a few projects linked off
there that fit your bill.

However, if this is as offtopic as I think it might be, you might want
to look at iptraf. It might even be installed on your linux system (if
this is a linux system). If not, I know there are packages for every
distro and source is available. Check it:
http://cebu.mozcom.com/riker/iptraf/

If you come up dry on both those fronts, you're probly going to need to
roll your own, and of course you can do so with perl and libpcap! Check
out these modules:
http://search.cpan.org/~kcarnut/Net-Pcap-0.05/
http://search.cpan.org/~atrak/NetPacket-0.04/

I'm using those two in conjunction with the rrdtool perl modules to
generate my own graphs.

That should hopefully be enough to get you started.
