Zabbix SNMPv3 help

[TadasIT]

Hi, fellow engineers,

I'm having hard time with monitoring MikroTik devices via SNMP.
I'm, trying to figure out why it's so unstable, cause I have zabbix server VM on cloud and using SNMP to monitor my companies different offices through out the country.
We having one WAN IP for all our sites and it's bridged through our ISP. So same WAN IP for all so we did port forwarding to target different Mikrotik devices on different offices.

Using SNMPv3 with SHA1 and AES128 and it's working, but it's so unstable, gets some data and SNMP goes red saying "Connection timed out", or "Probed successfully, but couldn't retrieve OID...."

The only MikroTik devices that is not having any issues is different model MikrotTik - RouterOS CCR1016-12G which is 1U rackable and others which is getting issues are all MikroTik hEX MMIPS - RouterOS RB750Gr3.

Can it be that MikroTik itself is heavily loaded and not having resources to keep on responding on time to zabbix?
I have increased pollers # and SNMP check interval without any success.

You could try increasing timeouts too. In server api to Administration->General->Timeouts.

Thanks for reply, I forgot to mention that I've already increased timeouts of SNMP to 15s

Hi.

I have a similar problem, but it only affects a few discovery categories with CRS326-24S+2Q+

only partial data received, cannot retrieve OID: '.1.3.6.1.2.1.2.2.1.14.36' from [[192.688.1.11]:161]: timed out

]# snmpwalk -v2c -c public 192.168.1.11 .1.3.6.1.2.1.2.2.1.14.36
IF-MIB::ifInErrors.36 = Counter32: 0

I have a timeout - 20 seconds
