[sllug-members]: Which Network Monitoring Solution?

[Nathan Lane]

Hi I am trying to get a network monitoring solution.  In the past we've
attempted to use Nagios, but couldn't figure out how to get it to monitor
whether a specific web page is accessible on a certain server.  Today I am
trying to set up an OpenNMS server to do the same thing, and I am still
running into road blocks - I can't find a straight forward solution and I've
been working on it for two days (same problem as with Nagios).  I just found
another one - Zenoss - and I'm wondering if it's any better/easier/simpler
to configure, or if it stands up to Nagios and OpenNMS.

Our platform is Ubuntu server 7.

Our environment is a mostly Windows XP/Server 2003 network

We want to monitor ICMP, HTTP, FTP, SNMP, and most important and difficult
(apparently) whether or not specific websites are accessible constantly.

Now I know that these [probably] all use slightly different models for
monitoring - Nagios is mostly SNMP, but has other capabilities and it's easy
to write plugins for using Perl.  OpenNMS has automatic "discovery" of
services, which we could really care less about, but it seems to be
difficult to make it check services that aren't "discovered", like this
website problem (discussed briefly above).  I haven't tried Zenoss yet, I
just discovered it on Sourceforge, and I've been lurking on their IRC
channel.  We currently use a commercial system called ipMonitor, which is
very pricey, and it doesn't even do everything that we want (though I can't
pinpoint what it was exactly that it doesn't do)  but the configuration part
of it is very self explanatory and straight forward.

So I need some help - in two areas, which system should I use, or is there
one the one-ups all of these, and can anybody help me configure it to check
whether a specific web page is accessible from the server (following
redirects automatically)?

Thanks
