Some problemes with graph (absence)

[Flo0r]

Hi,
I have a small problem graph.
I migrated from one machine to cacti on a machine B (Debian 6.0 and PHP 5.3).
After some adjustments to our internal tools, cacti working again but there are absences of some graphics (like the picture).
What causes these absences? too much data to poller?

Some information:
SYSTEM STATS: Time: 7.3509 Method: spine Processes: 1 Threads: 30 Hosts: 37 HostsPerProcess: 37 DataSources: 412 RRDsProcessed: 245

Goto Graph Management, edit one of the graphs and Press the Debug link to see the reason.

There is no reason ...

RRDTool Says:

OK

I think it was during the audit cycle. If a host does not respond within the allotted time, there ... nothing.

The reason that you have an absense of data is that the Cacti was not polling between those times, or you made some mistakes or left out steps while migrating.
