Hello,
From time to time there are few devices that lists on the hosts dashboard as SNMP not available, very few. I have around 300 network devices monitored and sometimes (randomly) 2 or 3 are unable from Zabbix to monitor via SNMP and the SNMP icon turns red
The Zabbix architecture is distributed
Zabbix Server 5.4.9 in Ubuntu 20.0.4
Zabbix FrontEnd 5.4.9 in Ubuntu 20.0.4
PostgreSQL DB 12 in Ubuntu 20.0.4
Zabbix Proxy 5.4.9 with PostgreSQL DB in Ubuntu 20.0.4
To avoid configuration mistakes i am using API to deploy all devices with a python script (create device and assign template), and once i run it in about 5 min all the SNMP icons turn green, but in a couple days few turn red.
All of the devices are being assigned to the Proxy, and when I find them in red, I can ping from the proxy and also snmpwalk, so the communication is okay and also the snmp configuration
When a host is unreachable, the snmp icon turns red and the message is the following: Cannot conect to "device ip:161".: Timeout
However when the scenario i am asking happens, the snmp icon turns red and the message is the following: Timeout while connecting to "device ip:161". but i can run with no problem the snmpwalk from proxy, so i'm of confused
Can you gime me some ideas where to start digging?
Much appreciate your help
