Hi!, I was wondering if anyone using Nagios has experienced instances of NRPE timeouts when DNS goes down. We had a incident where one of our web servers starting shooting out tons of:
“CRITICAL - Plugin timed out while executing system call”
when one DNS server became unreachable. However, in our /etc/resolv.conf we have a secondary if the first goes down so I don’t know if NRPE has any logic to use secondary name server when primary name server goes down?
Is NRPE smart enough to know if 192.168.1.1 goes down use 192.168.1.2?
We are using NRPE Version: 2.8.1 on the server in question.
