One of our complications is that a number of these systems will not be routable from time to time (this is because of VPN policy outside of our control). During those periods (possibly several hours long), the cluster of machines is disconnected from our network and not routable. </FONT></SPAN></DIV> <DIV><SPAN class=885334514-28072005><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=885334514-28072005><FONT face=Arial size=2>One solution I can think of is to have a simple wire-protocol that transfers nagios requests (or ncsa data) not over a network connections, but for instance a simple serial interface (the machines that server the disconnected networks are in the same room). I could imagine building an adaptation of ncsa/send_ncsa or nrpe that does not use network sockets, but a different interface (such as serial). The development work is not the problem for me, but I would like get some feedback on whether this is a feasible or sensible approach..</FONT></SPAN></DIV> <DIV><SPAN class=885334514-28072005><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=885334514-28072005><FONT face=Arial size=2>Has such a thing already be attempted?
