[Xymon] How to get vmstat5 to show on Trends page

Hey all, I'm trying to figure out how to get the vmstat5 graph to show up on the trends page for a 4.3.3 installation. I've tried adding vmstat5 to the GRAPHS statement in xymonserver.cfg, as well as vmstat::1, vmstat::5, etc with no success.

Suggestions?

Thanks! --Patrick
