I am trying to get a windows performance monitor

Using:
$USER1$/check_nt -H $HOSTADDRESS$ -s "$ARG1$" -p 12489 -v $ARG2$ $ARG3$ $ARG4$
Arg1 = NSClient Password
Arg2 = COUNTER
Arg3 = -l "\\MSSQL$LIVE:Databases(MPS3)\\Data File(s) Size (KB)","Size is %.2f %%" -w 90 -c 100
I keep getting 0, then I know from the performance monitor is around 79gb.
Ive tried command line variations on this
/usr/local/nagios/libexec/check_nt -H 10.4.2.63 -s "password" -p 12489 -v COUNTER -l "\\MSSQL$LIVE:Databases(MPS3)\\Data File(s) Size (KB)"
/usr/local/nagios/libexec/check_nt -H 10.4.2.63 -s "password" -p 12489 -v COUNTER -l "\\MSSQL\$LIVE:Databases\(MPS3\)\\Data File\(s\) Size \(KB\)"
Any ideas why this returns nothing?
