Issue's with graphs haveing null values.

[ZooyorQ]

Everything appears to be working normal, snmp is pulling data, the graphs are being generated, cmd.php is running every 5 minutes.

Also, when I goto Graph Debug, it just hangs.

Any ideas?

Its IIS6/Win2k3

I tried using MRTG and I get the same results, all my graphs show up 0 but my walks etc seem to be fine, it finds the interfaces etc... What do you suppose could be the issue. I'm using all Cisco 3550 Switches.
