[Xymon] Lower granularity for graphs in xymon

Hi All, I am wanting to capture data for 10 seconds granularity. I have configured the rrddefinitions to create 10 seconds sample.

But, the graphs still show 5 minutes sample. How do I make the graphs show the 10 second sample stored in the rrd files.

Any help is very much appreciated.

Thanks, Naveen
