contact_groups not working

[colinjack]

I am new on here - hope someone can give me a pointer.

I have installed Nagios Core 4.01 on Centos 6 and all is working fine.

Initially I just set up using the default setup (adjusted to suit my environment). My problem is with email notifications.

If I leave the hosts to inherit the admins contact_group from the template it all works fine. Email alertss get sent out as expected.

I want to have different notification groups for different hosts, so added a second contactgroup to contacts.cfg with suitable contact defined:

define contact{
contact_name secondline
use generic-contact
alias James
email james@domain.com
}

define contactgroup{
contactgroup_name secondline
alias Second Line Support
members secondline
}

I then added the contact_groups variable to the host:

define host{
use cluster-host
host_name Cluster 2
address 192.168.10.222
hostgroups cluster-hosts
contact_groups secondline
}

Alerts for Cluster 2 still come to the default admins contacts group, but not to the new secondline group. I expected the host setting to override the template setting.

Can anybody see what I am doing wrong? Seems pretty straight forward to me

Thanks

Colin

To me it looks like you have the contactgroup secondline defined, you are pulling it into the service, but the only member of the group you have defined is called secondline and that only has the single address, you need to create a new contact for each additional address, and define that contact in the contactgroup.

I do have other addresses defined and added to the admins group - and that works fine. The problem is that the admin group still gets alert emails for cluster 2 even though I only have the second line group in the contact_groups variable. What I cannot understand is why Nagios is ignoring that entry and using the default from the template (i.e. admins). I would expect alerts for Cluster 2 to only go to that one email address (james@domain.com).

I have left all the other entries from contacts.cfg and linuxhosts.cfg off my post to avoid a huge post - just posted the relevant entries.

[colinjack]

Right - I have come to this from a different direction

1. Created a new user and group in contacts.cfg:

define contact{
contact_name colintest
use generic-contact
alias Colin Test
email test@icloud.com
}

define contactgroup{
contactgroup_name testgroup
alias Test Administrator
members colintest
}

2. I have then created a new host entry for a fictitious host (so this will fail every test )

define host{
use linux-server
host_name Test Server 1
address 200.21.100.160
hostgroups linux-servers
contact_groups testgroup
}

3. Restart nagios service ... let's see what happens! I should get alerts in my iCloud account.

[colinjack]

Hmmm ... well that didn't work either.

I must be missing something but what? Anybody able to help?

Thanks

Can you show us the " linux-server" template definition? Do you see anything in the mail log?

Code: Select all

tail -50 /var/log/maillog

[colinjack]

define host{
name linux-server
use generic-host
check_period 24x7
check_interval 5
retry_interval 1
max_check_attempts 10
check_command check-host-alive
notification_period workhours
notification_interval 120
notification_options d,u,r
contact_groups admins
register 0
}


Tail on maillog just shows the emails for admins group - which I receive. The admins contactgroup works fine.The problem just seems to be with trying to get another contact group to work.

Thanks for the help - has to be something silly that I'm missing although I can't think where.

Are the notifications for the other group showing up under Reports > Notifications? If they show up there, but not in the maillog it's likely an issue with the email handlers for that contact.

[colinjack]

Notification report only shows notifications that are working (and were emailed). The whole system works fine apart from this second contact group. I need to spend a bit more time checking through I reckon.

I have created a new 'vanilla' 4.0.1 install on a new Centos 6 VM to play with over the weekend to see if I can get to the bottom of it.

Appreciate the help.

Great well let us know what you come up with! I do understand that is how the report works, that's why I wanted you to verify if it shows the emails there or not.
