Nagios Service reports wrong server

another day, another issue.....
I have 2 servers FMS1 and FMS2 (both are windows machines)
If I stop the nagios service on FMS1....in Nagios, it reports that the services for FMS02 cannot be reached (bad)
If I stop the nagios service on FMS02… in Nagios, it reports that the services for FMS02 cannot be reached (good)
From the CLI on the nagios server, i pinged both names and was returned the correct IP address for both machines.
I checked all the services, and host and the "Manage Hosts" button shows the correct server..
Any place else to look?

Can you post your related host / service definition that is causing these issues?

below is one of them.
If the below machine was no longer pingable, the Nagios display would say FMS02 wasn't pinging.
This issue is with ALL the services with FMS01
Code: Select all
define service {
host_name FMS01
service_description Ping
use xiwizard_windowsserver_ping_service
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
notification_interval 60
notification_period xi_timeperiod_24x7
contacts names
_xiwizard windowsserver
register 1
}
Code: Select all
define host {
host_name FMS01
use xiwizard_windowsserver_host
address FMS01
hostgroups Virtual,Windows-Servers
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
contacts Names
notification_interval 60
notification_period xi_timeperiod_24x7
first_notification_delay 0
notifications_enabled 1
icon_image win_server.png
statusmap_image win_server.png
_xiwizard windowsserver
register 1
}

When you are pinging the machines, are you using the DNS or the IP? Do you have anything hard coded in /etc/hosts?

Can you show us the host/service definition for FMS02 too?
Run the following commands and show the output:
Does the problem go away if you use the IP address instead of FQDN?

For the Love of God!!!!!
I found the issue
Some person, who I will need to disembowel, changed the server that the services applet on FMS01 to connect to FMS02.
Basicly, that explains why FMS01 never saw the powershell code in the ini file, and why when I went to stop the nsclient services on FMS01, nagios reported FMS02 was down.
Everything is working fine now.
You can close this issue.

These things happen sometimes.
I am glad your issue has been resolved!
