the "df" plugin reads a list of mountpoints (using getmntent(3) when on
Linux) and calls statvfs(2) only for returned directories. I assume that
unless the filesystem is in fact mounted, possible targets of
automounter are not returned by getmntent(3).

If you use the file system and it is actually mounted, collectd should
pick it up and report statistics. I don't know if this counts as "usage"
of the file system, so it might be that it these file systems are not
unmounted automatically when collectd is running [*].

Hope this helps,
regards,
