Monitoring Windows workstation

[Xavier Mertens]

Yes, NCSA is a very good alternative but unusable in my case... Well it's
another debate ;-)

It seems that there is no port or any existing send_ncsa.exe... :(
Anybody has more info?

Have you not heard of NSCA?

Using NSCA would be much better from the point of view of both
standardization and Security.

Having ssh access from unix clients to the server feels dangerous. I would
infer that this ssh access is automated and hence probably uses unprotected
ssh keys. This is a bit of a back door where all roads lead back to your
nagios server. You should strongly consider switching to NSCA for that.

On windows, if you want it as a passive check, I think the only way would be
to use something like Nc_Net which I believe supports sending passive
service checks to the nagios server. I haven't used it personally so I can't
vouch for it (it requires that you go around installing the .NET framework,
which makes it quite unportable and not easily deployable since even the
NET silent install is not silent but gives a popup, it would an ugly hack
to try to use Wsh to try to catch that to automate the install, hence I use
NSClient++ which is easy to deploy and I don't have to deal with any
installing more).

If there is a port of send_nsca which is the passive service check client
then I suggest you use that to call whatever check_plugins you want and sent
the result back to the nagios server. You will have to install an NSCA
listener on the nagios server of course but this is not difficult and it
gives you passphrase and encryption protection.

The idea for this plugin would not include the passive service check send,
as I want it to remain portable and independent of all Nagios execution
mechanisms so that anyone can use it in any setup with any technology they
are using for remote checks.

 From a design perspective, the remote execution mechanism and the actual
check_plugin should be separate and modular so you can mix and match.
