Thank you. Seems it works now for the monitoring.


However, still not ping-able from nagios to ubuntu server. I already talked to our network team and they confirmed they allow the ports / configuration and there's no issue with the network or firewall.

Server is down in Nagios XI Monitoring

This is the current setting of our hosts file.

root@azisgezrxcpq01:/home/vmadmin# cat /etc/hosts
127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

If you cannot ping from the nagios server on the command line to the IP of these servers if has to be either a network problem or something blocking ICMP like a firewall

Code: Select all

ping 10.10.20.11
This would not be within the Nagios software
