Nagios Support Forum

Greetings,

I'm looking for a way to monitor and alert our Windows file shares, specifically to alert on when a bulk file copy to the share is attempted by a user. We'd like to see alerts when it is happening. This will help us in responding to issues with our shadow copies and VSS. Thanks in advance for any advice!

I don't know of one that exists. I once wrote one, but that was under the employ of a former company so the code was owned and retained there. Here is where someone has written one that appears to be Linux compatible only:

If you're not averse to installing cygwin, it may *just work* in your case. Otherwise it doesn't look like the landscape has changed regarding availability of plugins for that use case.
