Help: No graphs in xymon

I am very new to Xymon so bear with me.

I am looking into a problem on Xymon 4.2.2. on linux with no luck.

Looking for some hints on how to proceed.

Graphs show up only in trends column but not in its own column.

This is not a custom graph that I am trying to create but the standard setup by

Xymon installation e.g., cpu, memory, disk etc. Only cpu has a graph but not any other

Columns. When I look in rrd directory I see la.rrd ( for cpu ) and multiple rrd for disk

disk,tmp.rrd, disk,var.rrd, disk,root.rrd. So I see 3 magnifying glass on disk page with

no graphs to go with it.

Any help appreciated,
