I’m using Zabbix 6 LTS on a separate server (not on my Nethserver). I’m working on a trigger to help me determine a host is truly down using two items which would result in a disaster alert:
Zabbix Agent on the host is not responding
Ping from host is not responding
There already are triggers for each of these items. But what if my zabbix agent stops working. While this can be a high alert for me to investigate I would want a way to double check my host and truly see if it’s down. I thought I could leverage the two items above to help me. So I created the following trigger (for now just tesint on my Linux Agent Template) using this expression:
last(/Linux by Zabbix agent/zabbix[host,agent,available])=0
But I don’t think I’ve created this expression properly to alert on my Zabbix Agent not being available and for ICMP Ping to the host.
Can anyone provide assistance on what expression I can use to help me satisfy these requirements. Or if anyone has a better solution to alert (disaster) on host down without only relying on the Zabbix agent?
