Hello. I have a question about SNMP values.
I’ve got Mikrotik RB751 and I got SNMP values on ether2 port such as ifInOctets.2 or ifOutOctets.21 (speed per second)
I made a graph on Zabbix with this values.
Now I’ve got VLAN interface on physical ether2 (ifInOctets.2) interface.
VLAN SNMP values is called ifInOctets.30 and ifOutOctets.30.
So now I need to separate VLAN and ether1 traffic speed values.
I’ve made calculated item - last(“ifInOctets1”)-last(“ifInOctets30”)
and I got incorrect values in petabytes/s and exabytes/s
Then I read SNMP values of ifInOctets.1 and ifInOctets.30 by MIB Browser.
Here is it
ifInOctets.2 = 97590243
ifInOctets30 = 554438260
Name/OID: ifOutOctets.2; Value (Counter32): 1175292255
Name/OID: ifOutOctets.30; Value (Counter32): 892442707
How does it possible?
I thought that ifInOctests30 should be less number than ifInOctets.2, because it’s VLAN “inside” ether2 (ifInOctets.2)
Thanks!
