Hostname not showing up in email notification

[luniversity]

profile.txt

I'm new to Nagios and have just taken over our system and I need a little help fixing an issue. I have about 15 hosts which do not display the host_name in either in subject or the body of the email in notifications when an alert is triggered.

I've looked through the FAQ's and searched the forum but still no luck finding a solution to my problem. Can anyone give me any ideas on where to look?

I've attached the output for my system profile.

Does this happen for all users that would get notified for these devices or just some of the users?
Also I should ask, are these just core config manager contacts, or full XI users?
finally, for the moment, are you using sendmail or smtp for sending alerts?

[luniversity]

Yeah all the users that receive the notification see the same thing. The hostname is missing.

All users are full XI users.

And I believe we are using SMTP but I'm not sure. How can I verify that?

[sreinhardt]

Since they are all users, smtp settings would be in Admin-Manage Email Settings. Could you give an example of a user and the service causing the issue? Also just to confirm, what should be hostname is not showing as an IP, it is just missing entirely correct?

[luniversity]

I was wrong, the mail settings show sendmail.

An expample is would be my user account (cmwestmorel) is an admin account which is setup to receive alerts from all the hosts. The particular email I get looks some thing like this:

Subject: PROBLEM Service Alert - // Disk Usage is WARNING

***** Nagios XI Alert *****

Nagios has detected a problem with this service.

Notification Type: PROBLEM

Service: / Disk Usage
Host:
Address: 192.168.245.20
State: WARNING
Info:
DISK WARNING - free space: / 2859 MB (20% inode=95%):

Respond: https://nagios.lamar.edu/nagiosxi//rr.p ... 21a5594f50
Nagios URL: https://nagios.lamar.edu/nagiosxi/

This service checks disk usage on the root (/) of this Linux host (RHEL 4) btdwappprod.lamar.edu. When I go to Admin -> Notification management my setting under the email tab look like this:

Host Alert Subject: %type% Host Alert - %hostalias% is %hoststate%

Here is the host config:

I suspect that the alias field for this host is populated with some whitespace which is causing the problem.

Code: Select all

  alias             

Go and check that the alias field for the host is completely empty, save the host object and then apply config.

Well now I have another issue, not sure it's related. When I went into CCM and edit the host "Description" field (which was blank) I save it. But when I hit "Apply Configuration" I get a "Configuration verification failed" error. The snapshot of the configuration shows theses errors at the end of the file:

Code: Select all

Error: Could not find any contact matching '`÷®' (config file '/usr/local/nagios/etc/contactgroups.cfg', starting on line 50)
Error: Could not expand member contacts specified in contactgroup (config file '/usr/local/nagios/etc/contactgroups.cfg', starting on line 50)
   Error processing object config files!

I looked at the config file '/usr/local/nagios/etc/contactgroups.cfg' and line 50 shows this:

Code: Select all

     50 define contactgroup {
     51         contactgroup_name                       DBA
     52         alias                                   LU DBAs
     53         members                                 nelsong,ppilli1,swilkins
     54         }

I'll post this issue on a separate thread and try again.

Are all these (nelsong,ppilli1,swilkins) valid contacts? I would be probably easier if you sent the profile.zip to [email protected] for review.
