Some of graph from network interface come only with a few point in the graph.

It can happens when you have a small Timeout and your SNMP collector cannot get a data in time.

Try to increase value of timeout up to maximum 30 seconds.

[B]/etc/zabbix/zabbix-server.conf[/B]
Timeout=30

Aleksey offers good advice.

Then, after you do that, have a look at the last paragraph of this post and the graphs that at the bottom: https://www.zabbix.com/forum/showthread.php?t=41219

Then check your setup to see if your Zabbix processes are struggling to handle the workload. If your pollers and/or trappers are overloaded, this can also contribute to what you are seeing.
