I have an agent on the proxy server that has a public IP address, and that's why I can add those nodes manually. How to do relay agents on proxy server?

That could be great to have a section about Network discovery and how to discover nodes behind a proxy and their corresponding parameters in server configuration. I think every sys admin would love to automate his work.

I can successfully discover nodes on the local network, but I have problem discovering nodes which are behind a proxy server. How to discover nodes behind a proxy server?

I have found the solution. As someone else might come across this thread: 

I should have used FileSystem.Free({instance}) instead of FileSystem.Free([instance]). I followed a youtube video which I think was a little bit old and it used [] rather than {}

Why I get the attached error when using the below configuration: 

Parameter: FileSystem.Free([instance])
Instance discovery -> Agent list -> FileSystem.MountPoints

Why should I get an error like this? I should note that when I fetch data manually it works ok.

When I run agent on debug mode, the below result is shown: 

23-Aug-2015 14:18:41.732] [DEBUG] [session:0] Received message CMD_GET_PARAMETER
[23-Aug-2015 14:18:41.732] [DEBUG] [session:0] Requesting parameter "FileSystem.Free([instance])"
[23-Aug-2015 14:18:41.732] [DEBUG] [session:0] GetParameterValue(): result is 500 (INTERNAL_ERROR)
[23-Aug-2015 14:18:41.732] [DEBUG] [session:0] Sending message CMD_REQUEST_COMPLETED (size 32)

Actually it is not a directory. I used df -h to see all available partitions. /var is one of them. I've got some new information! There are some NFS on /var partition! I think netxms cannot get correct available space due to NFS in /var....

I used instance discovery with FileSystem.MountPoints and I could see that there are some nfs inside of /var.
What should I do now?

Instance discovery list all partitions, but with error. The below picture shows just a portion of partitions. /var is part of them.

Filesystem                                                  Size        Used      Avail        Use%          Mounted on
172.16.131.2:/var/storage/files/inbox          45G        18G        25G          42%            /var/storage/files/inbox

FileSystem.Free(/var/storage/files/inbox) shows 29G!
FileSystem.Avail(/var/storage/files/inbox) shows 26G!

In Netxms dashboard I used the below parameter to get / free space:

FileSystem.Free(/)
Now I want to get a specific partition's free space as below:

But it gives incorrect free space. How to get /var free space?
