tag_summary = "Retrieves disk space statistics and information from a remote NFS share. The output is intended to
resemble the output of 'df'.

The script will provide pathconf information of the remote NFS if the version used is NFSv3.


SYNTAX:

nfs-statfs.human:  If set to '1' or 'true',
shows file sizes in a human readable format with suffixes like
'KB' and 'MB'.


mount.version:  number If set overrides the detected version of mountd


nfs.version:  number If set overrides the detected version of nfs


rpc.protocol:  table If set overrides the preferred order in which
protocols are tested. (ie. 'tcp', 'udp')";
