We try to stay away from the Windows NRPE and use it only very special cases. Instead we use Net-SNMP which has been around since 1992. There are 32 and 64 bit Windows and Linux binaries available from the project's website at http://www.net-snmp.org/. Nagios just performs an snmpwalk to get the data. We also use it for our Solaris, AIX, Linux and FreeBSD hosts. (We don't have HP-UX hosts, but my guess is that it should be available too). That way we have a single Nagios implementation across all our platforms. More specific on the Windows hosts, here's an example of what we monitor via Net-SNMP: - Check if the event log service is running? - Check the load on Windows servers. - Check the bandwidth on the various network interfaces. - Check the memory usage. - Check if terminal services is running? - Space on all disk drives (i.e. C:\, D:\, etc) - Uptime verification. - IIS website validation (per site validation check). - Check if the FTP service is running? (we can also login to test it) - Check if the Antivirus definition is up-to-date. - Check if SQL Server is running? Diego on this list has mentioned nsclient++ (http://nsclient.org/). I didn't know about it but will check it out. Let me know if you need even more details. > Thanks for any insights! > > Martin Anytime! David -- //www.freelists.org/webpage/oracle-l
