Ive been using Robin Mesh, and really like the fact that I can get the routers to check in via HTTP so you can check they are running etc vi a status page. Ive had a quick google on the site, but cannot find out if its possible to implement something similar via the schedule/crontab.
I wish we could use better monitoring tools, however, at many locations we are forced to install behind firewalls where we have no control over the core router. By having the routers check into a web page every 5 minutes we can at least see when they are on and give the customer an automated SMS/IVR call when they get turned off.
