Nagios is sending alert notification to the unselected group

[dbsaust]

Hi Everybody,
We have created alerts through Nagios XI but group is not selected in the Notification section but still unselected group is receiving emails/sms.

Could you please advise if you are aware of such issues. Do we need to check some config file, does it contain notification contacts?

Thanks

Are you talking about a service object or a host object?

If it is a service object, does the service have any contact groups assigned to it? Does the host have any contact groups assigned to it.

Can you please look in the file /usr/local/nagios/var/objects.cache and find the host and/or service definitions and paste them here.

Hi there,
I am talking about Service object, in service alerts we haven't selected groups but we are getting alerts but we have selected groups at the host level object.

For example,
I have a host called TEST1
and there are many services associated with host TEST1
for example : Monitor ABC Folder..
We haven't selected group for Monitor ABC Folder but we have selected group for TEST1.
We have selected many groups at TEST1.

But we don't want to send service alerts to unwanted group.

I will try to find objects.cache file

Thanks.

Hi there,
I was able to find definition in the txt config file from Nagios XI core config manager, I hope this is what you need.

Code: Select all

So the behaviour of Nagios is that things like contacts and contact groups defined on the host get inherited by the services.

https://assets.nagios.com/downloads/nag ... tance.html

If you have a service that you don't want inheritance to apply, then you can do the following:
CCM
Edit Service
Alert Settings tab
Click Manage Contact Groups
For the Contactgroup options radio select "standard".

Save and apply configuration.
You can test this by sending a custom notification from the service.

Does this fix your problem?

Hi,
For the Contactgroup options radio select "standard"
We have already selected "standard".

Hmm I've done some more reading and I found this thread:

https://support.nagios.com/forum/viewto ... 750#p76073

Contacts on a host will *always* be contacts for that host's services except when a contact is defined on the service object itself.

I'm thinking that instead you could create an empty contact group called "No Contacts" and assign that to the service, this should then override the inheritance.

I might need the USA techs to chime in on this tomorrow to see if they have any other information on this.

We have selected contact group in the services but still it is picking from Host level contact group.
Please let me know if you have any other information.
