There is also nsclient++ that I'm currently using and is very versatile. (see http://www.nagiosexchange.org/). It uses NRPE and has other beneficial tools. A very good tool that I am looking into expanding to another 150 Windows servers. The only issue that I have is with how performance data is displayed. I don't believe it follows the Nagios standard on metric output so I'm having a problem integrating it with PerfParse (Graphing Performance Data). Steve Nagios 2.4b FedoraCore3
