I recently switched from what was very reliable DSL service to cable. Since I've switched, I've had intermittent connectivity losses and extremely poor service. When the cable is up, I'm getting over 4Mbps down and it's great, but it's not up all the time. Given that I'm a network engineer by profession, I've been giving the cable company the benefit of the doubt. I troubleshoot the connectivity issue, and pretty much always determine that it's on their end. As such, I don't want to pay for such shitty service. I've called their TAC several times, and most recently I was told that this is not normal, that some maintenance was being done and equipment being replaced (at 6PM in the evening ><).

At any rate, I'm looking for a piece of software that does something specific. I want to monitor my connectivity to the Internet and be able to record the times that I have limited or no connectivity. In a perfect world, I'd like to be able to convert that time into a graph, and show connectivity loss. I'd also like to be able to add comments such as, 'cable modem lost physical connectivity' or, 'cable modem up, but no DHCP from ISP' or 'DHCP, but pings are intermittent to ISP's default router'. I have Whatsup Gold which will do all of that, but I'd prefer something simpler since I'm not really concerned with monitoring an enterprise or server services.

Thanks in advance.

This sounds like something that could be done easily using MRTG to graph response time to a remote site. There are tons of contributed scripts all over teh intarweb that should either do what you want out of the box or give you a good start towards writing something on your own. The main site for MRTG is <a href="http://people.ee.ethz.ch/~oetiker/webto ... /">here</a>.

Personally, I use <a href="http://www.opennms.org/">OpenNMS</a>, but that may be too heavy for what you're wanting to do, although it does a great job of monitoring traffic and response times.

I've used MRTG a bit in the past. I'll try it out now and see if it does what I want in a simple way.

take a look at cactii also. kind of like MRTG.
