This looks to me like you're trying to execute $gmetric with the given parameters. I know in bash you can do

CMD=/bin/tr
PARM1=a-z
PARM2=A-Z

$CMD $PARM1 $PARM2

and have it execute /bin/tr a-z A-Z, but that doesn't work in perl. You'd have to do something like

system("$gmetric $gmetric_conf --name=VVname  --value=$pVVname --type=
+uint32 --units=name");
system("$gmetriC $gmetric_conf --name=t  --value=$t --type=uint32 --un
+its=t");
system("$gmetric $gmetric_conf --name='I/O per second Cur'  --value=$i
+oCur --type=uint32 --units=ioCur");

Normally I'd be inclined to use the multi-arg version of system, but that wouldn't work here since $gmetric_conf contains more than one parameter.
