 NFS plugins for FreeBSD
 ------------------------
 
-NFS plugins for FreeBSD
+The NFS plugins for Munin depend on the /proc filesystem in Linux for
+statistics which does not exist in FreeBSD by default. While one can
+add the linproc package to their installation to emulate this
+functionality, I felt it would be better to write plugins that made use
+of native tools.
+
+I'm leveraging the nfsstat command to create these plugins. I'm sure
+there is a better primary data source in FreeBSD to gather this output
+from but for my purposes, using nfsstat is adequate and acceptable.
+Unfortunately this means if the output of the nfsstat command changes
+due to updates, these plugins will likely report inaccurate data.
+These are the days of our lives, as they say. Someone with appropriate
+levels of FreeBSD knowledge can probably improve these plugins
+trivially.
+
+I'm specifically targeting FreeNAS/NAS4Free, but the code should work
+on any FreeBSD system with minimal package additions. Installing munin
+on FreeNAS is not supported in general, but it's easy enough to do and
+I wanted it monitored, ergo we are here.
