Hello, I am pretty new to Nagios and set up a box up in our data center. Right now, we pay yearly licensing for some other software which I feel is not that great and from what I have read and the little I have worked with Nagios, this appears much better. In my spare time I am setting up this Nagios box. My hope is that i can get it the way I want before the next yearly licensing comes through on our current network monitoring software so that we simply will not renew and move over to the Nagios box. Anyway, one of my tasks is to obtain the WAN address for a series of routers at remote locations (~100 locations). I have been trying to find the appropriate SNMP query for this but have come up short. When I do an snmpwalk, the only thing I can find that has the Internet IP is this: .1.3.6.1.2.1.4.20.1.1.THE.INTERNET.IP.ADDRESS = IpAddress: THE.INTERNET.IP.ADDRESS where THE.INTERNET.IP.ADDRESS is the actual address I am looking for. This is in the IP-MIB::ipAdEntAddr table. However, I cannot query this since what I am looking for is part of the OID that I am trying to query. Is there anyway to get this information? I could snmpwalk then pass the output to a script that parses the output and finds the address easily enough, however, to snmpwalk 100 routers is not feasible. I would also like to set it up in Nagios where this is monitored and available to view or export a host-group to a report with this information. Any suggestions would be greatly appreciated. Thanks. Kevin
