Graphs not showing values

[qix]

Hello all,

I'm having trouble showing values in graphs that have been collected by Zabbix.

For example, I have the following values in my database:

DB000443: Processor load
Showing history of 3600 seconds(1 h)
[from: 2006.Nov.06 13:36:35] [till: 2006.Nov.06 14:36:35]

However, if I graph these values I get the graphic in attachment 'Screenshot Graph Processor load 1h.png'. In other words, it's not showing anything.

When increase the period with 4h I get the graph like attachment 'Screenshot Processor load 5h.png'.
In other words, everything looks fine.

I'm using zabbix 1.1.3 upgraded from 1.1.2.
The item has the following timers:

Update interval 5 sec
Keep history 7 days
Keep trends 365 days

I have this problem with various items, although not all of them.
I hope someone can help me find the solution to this problem.

The problems seems to be solved

I had already started tweaking my settings because I saw the queue's we're running full. This seemed to cause the problem with the values not showing.
I have set about everything that needs to be polled at least 300 seconds.

I should have searched the forum better though, I suddenly stumbled accross this post during another search:

http://www.zabbix.com/forum/showthread.php?t=3322&page=1&pp=10&highlight=threads

It described the same problem and solution.
