What are options then? Should I install NRPE agent ?

That does seem like the best option at this point. The best way to do this is through NSClient. Once you have NSClient installed, you will use the instructions at https://assets.nagios.com/downloads/nag ... ios-XI.pdf to enable NRPE. You'll want to start with https://assets.nagios.com/downloads/nag ... ios-XI.pdf and then move to https://assets.nagios.com/downloads/nag ... ios-XI.pdf

The best thing to do if you have issues with NSClient is to open up a new thread, unless the NSClient issues are directly related to the mount point situation. Otherwise, things will get confusing.

is there any way to monitor when it's mounted to folders?

I may be missing something, but if you want to check a folder's size, https://exchange.nagios.org/directory/P ... bs/details should work
