I am doing a project and need zabbix to monitor nodes, including 2 HPE Proliant DL380 servers. I am currently monitoring via SNMP v1 and have been able to monitor server parameters. However, when I shut down the server, I cannot push events to zabbix. I checked and found that the hardware cannot work. Besides, when I monitor other VMs via agent, the logs show as below and I cannot push events back. Please help me to resolve this quickly. I need it urgently for a client.
