Notification rules match, but no notifications sent

[SHerrmann (Stefan Herrmann)]

CMK version: 2.2
OS version: Debian 12

23-12-06 06:56:52,645 [20] [cmk.base.notify] Got raw notification (server.local;Interface 3) context with 52 variables
2023-12-06 06:56:52,647 [20] [cmk.base.notify] Global rule ‘Notify all contacts of a host/service via HTML email’…
2023-12-06 06:56:52,647 [20] [cmk.base.notify] → matches!
2023-12-06 06:56:52,647 [20] [cmk.base.notify] 1 rules matched, but no notification has been created.

I have set up a contact group, service group and notifications, but don’t get notifications. I tested the mail system with “echo test | mail -s test email@address.com” that works.

my collegue was already working with the checkmk system, probably he did something wrong. can you help to find out what the problem is ?

is your user a contact of the object in question?
does your user have an e-mail address?
can you make sure that your user does not have “notifications disabled”?

rarely:
if this is an older installation, make sure you don’t have an old (breaking!) configuration in your ~/etc/check_mk/conf.d/wato/contacts.mk → 'disable_notifications': False will break the notification processing

sed -i -e "s/'disable_notifications': False/'disable_notifications': {}/g" /omd/sites/${OMD_SITE}/etc/check_mk/conf.d/wato/contacts.mk

thanks @gstolz , checked the file and found a matching entry ‘disable_notifications’: {}, so it’s ok.

[SHerrmann (Stefan Herrmann)]

In that file there are all contact groups, cmkadmin has a ‘notifications_enabled’ : False, my user has disable_notifications’: {}. so looks as intended as the cmkadmin should not get notifications.

@gstolz

is your user a contact of the object in question?
does your user have an e-mail address?

what about these two?
Do you see your user in the contacts of the notification context when you analyse notifications?

(1) would be “show analysis” if you haven’t enabled that already

[SHerrmann (Stefan Herrmann)]

I can see notifications in show analysis like this:

But there is no icon in front that shows that a notification was sent nor do I receive a notification per E-Mail.

Please read my posts

can you confirm that your user is in the contact list for that host? See my screenshot for the notification context - it can be opened using the scripture/document icon.

does your user have an e-mail address configured?

[SHerrmann (Stefan Herrmann)]

I have opened the notification context, this is the output of an example:

I do have configured an email address for the contact and also put the contact into a contact group.

Hi Stefan,

ok - then something is not working with your assignment of the host/service to the contact group.

Check your rules in “Assignment of hosts to contact groups” (and if you need exceptions for services, also “Assignment of services to contact groups”)

You can also assign contactgroups to folders directly, I usually suggest against that, as it is less flexibel and harder to keep an overview, then when you have only rules. Especially when you start to mix assignments, it can get messy.

[SHerrmann (Stefan Herrmann)]

Ok got it. I had to use “assign servies to contact groups” and add a rule, then it worked. thanks for your help!
