Nagios Support Forum

Hi,

I have just upgraded to 2012 1.7 and all email alerts and notifications have stopped.

Please assist.

This is strange - the upgrade shouldn't change anything in your notification settings... Are your notifications enabled globally?

Go to: Home->Monitoring Process->Process Info

and see if you have a green dot next to the "Notifications".

Also, see when the last notification was sent:

Home->Incident Management->Notifications

Hi,

Thanks for your prompt reply.

Yes indeed there is a green dot and the notofications are showing on the notification screens. We are just not getting any emails.

Thanks

What happens when you try to send a test email?

Click on the "nagiosadmin" in the upper right corner next to the "Logged in as", click on "Send Test Notifications" under the "Notification Options" menu on the left, and click on the "Send Test Notifications".

You can also see what is in the mail log:

Hi,

I receive the test notification successfully. However, I still cannot receive any alerts and notifications. The tail of the log is below:

Hi,

Any help is appreciated with this issue. I really cannot spot the problem. The notifications are being created but not generating an email.

This is a live system and impacting production minitoring.

Thanks.

Can you post the output of the following please:
And: For good measure.

We are having the same problems, post upgrade. Fortunately, this is still on our POC box. Email notifications stopped after upgrading to 2012 1.7. We are running on RHEL6.

Oddly enough, emails to a pager address are working fine. However, emails to an email addresses are never getting to Postfix.

Here are some of the logs:

Hi,

Output is below:

# - destinations that match $virtual_mailbox_domains

Reloading postfix: [ OK ]


Still no email notifications. From the previous post, it looks like it is not an isolated issue.

Many thanks for your assistance.

As slansing mentioned, could you please run the following commands. It would seem from your logs that nagios is sending alerts to postfix just fine, however they do not seem to be queuing or delivering properly.

slansing:
Can you post the output of the following please:

Code: Select all

    cat /etc/postfix/main.cf | grep mailbox_size
    cat /etc/postfix/main.cf | grep message_size
    cat /etc/postfix/main.cf | grep virtual_mail

And:

Code: Select all

    /etc/init.d/postfix reload
