I have installed nagios, ndoutils and all went fine
to generate values in the form of graphs i need perfdata values
But in my nagios database the nagios status table and all other tables which contain perfdata is having NULL(empty space) as the value.
I have checked it by giving
process_performance_data=0 and 1 as well
but found no result.
how to get values in this perfdata
Any help appreciated,
