gaps in interface traffic graphs

[humit]

Hi,

I recently upgraded my zabbix server from 1.8.3 to 1.8.8. After the update everything seems ok, except one single graph.

This graph shows our main traffic on a juniper switch and after the upgrade it started to show gaps.

The current Item configuration is like this:

(tried both snmpv1/v2)
SNMP OID: IF-MIB::ifOutOctets["index","ifDescr","xe-3/0/1"]
Type of information: Numeric(Float)
Units: Bps
Use custom multiplier: 8
Update interval (in sec): 15 (tried different intervals up to 60 secs)
Flexible intervals (sec) No flexible intervals
Store value: Delta (Speed per second)

Rolling back to 1.8.3 didn't help. My traffic pattern is completely different now.

Any suggestins to resolve/debug this issue?

Best Regards.

Gaps in graphs can indicate zabbix performance problems: Try look at these links:

Or maybe you snmp device respond to slow – try to check the zabbix server log.

Thank you for your response.

Monitoring ifHCOutOctets instead of ifOutOctets seems to do the trick.
