Email notifications not working automatically

Troubleshooting
1

Hi there,

I am using checkmk raw v1.6.0p10 running on Ubuntu 18.04 x64.
Previously I was able to receive notifications automatically before an upgrade to Checkmk.

I can see notifications alerting under notifications but do not receive an email. When I click the replay notification arrows I receive the email notification in my inbox.

If i fake an alert by using the " Fake check results" command or generate an error on my servers to create a notification I do not recieve an email notification but i see the notification under notifications in checkmk.

Any ideas what I should do?

Thanks in advance

Do you see any errors in the notifiy.log ?

With the cmk user check:
cat var/log/notify.log

hi Constey,

I get the following. ‘cat: var/log/notify.log: No such file or directory’

it appears to be fixed.

Simply changed /etc/hosts file:

127.0.0.1     localhost localhost.localdomain
127.0.0.1     foo.bar

To this

127.0.0.1     localhost localhost.localdomain foo.bar

Sendmail looks for a fully qualified domain (FQDN) name and will use the localhost.localdomain in the single line version.
