Just add a "," at the end of the line, then the plugin works as a charm!
Dears,
That is almost half year, when this plugin is in production monitoring.
Yesterday, monitoring server was found died... halted because ... inodes finished.
# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/mapper/VolGroup-lv_root

tmpfs 1005525 1 1005524 1% /dev/shm
/dev/sda1 128016 62 127954 1% /boot
yep, that is 13,912,080 millions of inodes used
The problem found:
plugin invokes libnet-openssh-perl library which created files in uesr's (nagos) home directory, which created file for each performed check:
# ls -la /home/nagios/
drwx------ 2 nagios nagios 853970944 Mar 22 12:26 .libnet-openssh-perl
it took some time to count:

Keep in mind (after integrating).
Plugin itself is excellent!
