I am seeking to run software on my SN Server that will alert me if a device goes down. All I can find is Windows stuff. I live in an apartment complex that has over a hundred units and every unit has Internet access as part of the package. I was given the task of being the Johnny-onthe-spot for anything that goes down. I have found stuff like the <DUDE Network Monitor> that will ping devices on the network every so often, and tell me if hub is no longer responding to a Ping. However DUDE is a windows program and I am a Mac only person. I dont want something that is going to just search out one device, I need something to ping 100 routers about every 60 seconds 24/7, type of thing. I do have a Mini server running my in home file sharing so I have a server running all the time, although I am no expert at running servers. Running a file server is about all I know how to do with it so far. If anyone has any suggestion on what program I can use, please let me know.
