Hi,
today I had the following situation: My first DNS Server was in a planned maintenance and Zabbix started to mention that the Zabbix Agent wasn't reachable on all hosts.
I've checked this and this is definitely a false positive. All Agents where reachable. My guess is, that this false positive was simply caused due to a too short "timeout" as the check command takes a bit longer because of the slower DNS lookup (As the first DNS Host is down).
I've looked through the documentation and couldn't find an option how I can workaround this issues with setting a higher timeout or something similar.
Is there any option to fix this problem?
Btw: Within the resolv.conf I have multiple DNS Servers which are all reachable and the options are "timeout:1"
