I stumbled upon the problem that my Switch does not report its items in the configured time and the host is being disabled. snmpwalk from the Zabbix server works fine.
RouterOS version (both devices): 6.45.1
Zabbix version: 4.0.10
For my MikroTik switch (and router) I am using SNMPv3 with the following settings:
After LLD (Low Level Discovery) I have > 300 Items for the switch - most of them should report their values at the interval of one minute but some of them have a delay of more than one hour.
Code: Select all
/snmp export /snmp community add addresses=::/0 authentication-password="authpw" authentication-protocol=SHA1 encryption-password="encpw" encryption-protocol=AES name=monitoring security=private /snmp set firstname.lastname@example.org enabled=yes location=Home
For my router it is working way better but still not as it should (CPU usage of router is between 0 and 2%).
Zabbix in general does not seem to have a problem with SNMPv3 since other devices (NAS etc.) have their items reported properly in the given interval time.
I cannot see a high CPU usage using SNMPv3 on the switch. It is at about 2 to 3%.
Using SNMPv2 works perfectly fine.
Is there anything else I can test to find the reason for this?
