Nagios can do this. We monitor a dozen or so remote sites at work where they are small networks NAT'ed behind a single IP. Nagios runs out of cron on the workstations/servers at those locations and reports back to our main Nagios server. -b -- half a man's life is devoted to what he calls improvements, yet the original had some quality which is lost in the process. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: network monitoring of firewalled/NAT'd systems
Intellipool can run in distributed mode, where you have one monitoring server inside each firewall that reports back home to the mothership. http://www.intellipool.se/ Not *quite* what you asked for, but may serve. --DTVZ On Tue, May 18, 2010 at 5:48 PM, Michael ODonnell < michael.odonn...@comcast.net> wrote: > > > I wrote: > >We want to monitor (from a central server at HQ) the health and > >performance status of multiple machines [mostly Windows >-( ] at > >each of multiple customer sites despite them being NAT'd/firewalled. > > ...and then mentioned a bunch of features we're dreaming about. > > A more specific question: does anybody even know of a package that > can do "passive monitoring"?

A more specific question: does anybody even know of a package that can do "passive monitoring"? IOW, in our scenario some sort of agent on each workstation would be responsible for initiating a connection to HQ and pushing its own monitoring data back to our central server since we'd not be able to initiate connections in the other direction as they'd be blocked at the customer's firewall. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
