You can always keep an eye on uptime. Wiana lists it for each node or you can type uptime from a shell. If you need fairly immediate results, monitoring tools like Nagios or Big Brother are pretty good for roll your own monitoring and reporting. I'm finally updating my monitoring from Netsaint to Nagios. The plugins are real easy to write. Plus you can do passive service checks which is real handy when monitoring things behind firewalls. I've been using Netsaint for years to keep an eye on all my servers. It's been very helpful.

I agree with Glenn on the NaGios program for a little help watching the mesh. I am a few days away from getting my Nagios and Mrtg box installed at the main tower location. This will allow me to ssh securely into my monitor box and view a web interface and check host, services and bandwidth. Nagios will also e-mail and page me when it identifies a problem on the mesh. I have been running a test by monitoring a few meshap's with snmp and ping, it is great when you can call someone and ask about a problem rather than them call you about it. The software is easy to load and free, free, free --- did I mention it's free. I used suse 9.1 and nagios and mrtg came bundled with this distro.

Peter you can go to http://www.nagios.org/ and http://people.ee.ethz.ch/~oetiker/webtools/mrtg/ ---mrtg. You can run both programs on linux or windows, they where originally designed for linx and have been ported to windows. I recommend that you swing by your local computer shop and pickup a copy of suse 9. Suse 9 have the nogios and mrtg programs in rpm form bundled with the suse software. This makes it easy to load and offers some advantages in that your mesh nodes are a flavor of linux and your monitor box will be linux. We are about to begin installing a number of MESH networks and ensuring that our Support function is as fully equipped etc. as possible is obviously VERY important. As part of this, tools to help my guys monitor (performance, users, bandwidth, VOIP activity, QOS etc.), manage (i.e. addusers, MAC addresses, Re-boot etc. etc ) our MESH Boxes are going to be key to our success.
