Check Hyper-V VM Health

Thanks monkinsane :). Simple and easy to use. need little fine tune who all are using password. Below is the change i made. Thanks monkinsane :)

added "PSW=$2"

changed line #10 to OKVMS=`$CHNT -H $HOST -s $PSW -p 12489 -v COUNTER -l "Hyper-V Virtual Machine Health SummaryHealth OK"`

changed line #11 to CRITVMS=`$CHNT -H $HOST -s $PSW -p 12489 -v COUNTER -l "Hyper-V Virtual Machine Health SummaryHealth Critical"`

changed line #15 to CMDERR=`$CHNT -H $1 -s $2 -p 12489 -v COUNTER -l "Hyper-V Virtual Machine Health SummaryHealth OK" |grep -i -o "could not fetch information from server"`

It works, but since my NSclient++ machines require a password, I had to add a 2nd variable to the command line and threw that variable in to the check commands in the script so that I could pass it my password. Once I did that, it worked. I wish it would be a little more verbose or you could specify one particular machine, but I realize this is probably a limitation of Hyper V itself and not the script. It's at least giving us some info which is better than nothing.

The plugins work fine. If your are a noob like me... first install on your Windows HyperV nsclient++ without password.

If you are on Centos, you have to change the line 8 by CHNT="/usr/lib/nagios/plugins/check_nt"

I had the same problem as Cipher, where the script would bail at line 13. Turns out the problem is that this script has hardcoded a path for the check_nt script (CHNT variable) it depends on (I believe it was the default location for debian-based systems), and in my case (running on CentOS), that script didn't exist in that location. After modifying the path, there was another error that came up, this time the error was in the OKVMS & CRITVMS variables--my particular NSClient machines require a password, and this wasn't supplying one. So adding a -s to the end of those variables fixed it, and the script now works.

Version 2 of the script bailed on line 13 in my Opsview Core installation.
