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.
Switch: CRS326-24G-2S+
Router: RB3011UiAS-RM
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:
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 contact=mail@example.com 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?
