I've got about 2500 hosts ( in the xymon sense ). A large chunk are fake 
hosts for functionnal monitoring. A host ranges from 5 to 25 columns. 
Tests run every 5 minutes.

There is also a Vpage host that has ~2000 columns.

Load wise, the xymon server is on a VM with 8 vCPU and 8gb of RAM. Only 
596Mb of RAM is actually counted as used by processes, and that would 
include apache and everything else.

The only thing that has been clunky is the multi-server failover, but it 
works well enough.
