Network graphs show useless data

[Hemera]

Hi Everyone,

Currently I'am trying to have our bandwidth graphed by zabbix, however these graphs are rather useless since they show huge gaps/drops/spikes.
Is there something we should do differently or maybe we should not be doing this at all?

(look at the attachments for how it looks and how it should look)

Hope you can give me some advice!

How log setting for Timeout in zabbix_server.conf?
Default value is 3 seconds.

Probably, I think timeout was occured.
Please change to more long time for timeout seconds.

The config says:
Timeout=10

I more think that it's the overflow of the int in the router which resets to 0 if it reached and zabbix is not handeling that correctly

What are you use OID?
And, Are that OID's values are 64bit length value?

the result if I do a manual snmpwalk:

iso.3.6.1.2.1.2.2.1.16.14 = Counter32: 959278309

the result if I do a manual snmpwalk:

iso.3.6.1.2.1.2.2.1.16.14 = Counter32: 959278309

It's 32 bit counter.
Please, switch to 64 bit counters and it probably will fix the problem.
Try OID

iso.3.6.1.2.1.31.1.1.1.6.*
