Hi,

I am trying to collect the performance counters on the windows system using the below configuration. But I am getting the following error. Please suggest me any solution to overcome the error.

The error reported is:  
undefined method `value' for nil:NilClass

Here is my config file.

input {  
wmi {  
query =\> "select \* from Win32\_PerfFormattedData\_PerfOS\_Processor"  
}  
}  
output  
{  
stdout  
{  
codec =\> rubydebug  
}  
}  
Please suggest me if there is any other way through which I can collect the performance counters of the system.

Thanks,  
Jagadish
