Testing and troubleshooting intermittent ethernet connectivity at.......... - UPDATED

Looking for some insight how how to best proceed on problems like this at customer locations. We have some network management tools for this but nothing really seems to be specific to the task of troubleshooting the dreaded "It just stops working for a minute" problem.

The network path is a gpon layout to the customer prem where we terminate the fiber in an ONT and hand off ethernet on the customer facing side. While its rare we will sometimes have customers state that their internet drops out a few times a day. Of course dispatching a technician to verify connectivity onsite is a wasted effort as the services restore within a few minutes.

As I said we have network monitoring applications and we never detect any drops or outages. Historically its almost always something on the customer end, but this isnt a cut and dried statement either as there have been some issues where it comes back to our equipment.

Ideally, in my mind, I would have a piece of test equipment that I could install at the customer location and leave it running throughout the day or over the weekend. Problem is I run into a wall when it comes to finding a device to do this. I dont want a multi thousand dollar test set that simply sets on a desk in the back room and while a small laptop running an extended ping would give us some diagnostics that solution seems far from perfect.

Assuming the best course of action is what I believe which is to leave test gear onsite for an extended period of time does anyone have recommendations on the equipment to accomplish this?

Complex question for which I don't have enough experience to really answer. Are you solely thinking using a Windows system to monitor their network? Linux may have a few add-in features that may allow you to shine more light into the situation; again, I'm too inexperienced in WAN networking to really say. Perhaps using a simple custom router box in the clients home that logs network activity, and is scripted to ping/trace-route when disconnected and log the results?

Food for though, wish I could be of more help =(

I'd be happy with a $4-$600 solution that monitors performance and uptime. Most of the handheld test sets I've seen are a bit costly to leave unattended and/or run off batteries and dont have an AC option.

I cant imagine theres not a good solution to the problem, I'm just not aware of one. Hence reaching out to the group as this situation certainly isnt unique to me. The only stipulation I have which may indeed make it somewhat unique is the cost factor.

There may be a Linux solution which bears some looking into. It would be rather fun to grab one of those low dollar laptops and put a Linux install on it with some monitoring applications and play around with it. For that matter there may be some Windows apps which would make things a bit easier in the sense you could use the pre installed OS on the laptop.
 
May have found just the thing from Visualware!

They have a utility called RoutePlotter. Playing around with it now on my laptop but it looks like the cats meow for what I'd like to do. I'd recommend trying out the demo version for anyone interested.
