Hello there!
I am testing some cluster information gathering, and i am having some trouble.
I have 10 hosts ( linux1,linux2,linux3, linuxN ) that have the
"check_command check-host-alive" option under its host
configuration. Then, i've configured a service like this:
define service{
use generic-service
host_name VirtualCluster
service_description Linux Cluster Status
is_volatile 0
check_period 24x7
max_check_attempts 10
normal_check_interval 2
retry_check_interval 1
contact_groups linux-admins
notification_interval 240
notification_options w,u,c,r
notification_period 24x7
check_command
check_host_cluster!5!9!/usr/local/nagios/etc/linuxhostcluster.cfg
}
The host VirtualCluster is a host i "virtually created" that
represents the system where nagios is running from and has the option
"check_command check-dummy" activated. The problem is that at the
Service Details on the web frontend of nagios i get this:
VirtualCluster Linux Cluster Status OK 27-08-2003 21:41:00 0d 0h 5m 58s 1/10
Host cluster ok: 0 up, 0 down, 0 unreachable
( First of all...its not OK....)
Then, on the host details:
linux1 PENDING N/A 0d 0h 7m 7s+ (Not enough data to determine host status
yet)
This line repeats on all of the linuxN boxes. Whats the problem ?
