Nagios 3 was installed on Ubuntu 10.04. Then I have changed IP and default gateway on this server.
Occurs error
CRITICAL 2010-05-21 14:10:36 0d 19h 32m 17s 1/4 CRITICAL - Host Unreachable (99.99.99.99)
where 99.99.99.99 – is old default gateway of this server.
I have changed default gateway in file /etc/nagios/conf.d/host-gateway_nagios3.cfg
to the new gateway.
Then I restarted and reloaded Nagios, but there is same error.
Where should I change default gateway of Nagios server to delete this error?
