Nagiosgraph is not working for new graph service

[msachikanta]

Hi,

It seems nagiosgraph is not generating rrd file if I am adding new graph service. For example, I have added graphed service called 'Mem Usage - Physical', after restarting Nagios Service rrd file is not getting generate for Mem Usage - Physical and getting the below error. Could you please advise on this.

No data available: host=hostname service=Mem Usage - Physical db=

Please advise how it can be resolve.
