Why is the measurement of outbound traffic from this host always higher in Zabbix?
We migrated our Zabbix from version 1.8 to version 2, and then to version 4 LTS. We have already adjusted some things, however, yesterday we found that outgoing traffic from a proxy is much higher in the values collected by Zabbix, where iptraf shows around 800 kbps and Zabbix 1.4Gbps. But the most curious thing is that although this item is in the Template OS Linux, other hosts that also have it, do not show as much difference between iptraf and the value collected by Zabbix.
There are two subtle differences between the "pure" version of Zabbix, and our migrated system:
key: net.if.out[eth0,bytes] (in pure version is only "net.if.out[eth1,bytes]")
type of information: Numeric (unsigned)
unit bits/s (in pure version is "bps")
preprocessing:
change per second
custom multiplier 8
Or is this an agent or server bug, perhaps fixed in later versions?
System versions:
Zabbix Server: 4.0.16
Zabbix Agent: 4.0.2
