I'm not having a lot of luck digging into a problem in Xymon, so I'm looking for some hints on how to proceed...

I've installed Xymon 4.2.2 on several systems (one server) and it appears to be running correctly. However, only the CPU column is producing graphs of the historical data. I could swear that other columns (like MEM and DISK) produced graphs when I initially set it up, but it seemed that these other columns stopped producing graphs after the data moved from "Recently changed" to "Last change > 24 hours". The detail page still shows the magnifying glass, but no graph to go with it.

Anyone know what the problem is? Is there a method for debugging this?
