[Bone8Head]

How many CPUs do you have on this machine?

4 CPU
4GB RAM (but Guest or Host memory sometimes can be full)

43 of 70 GB Used (I don't know how Nagios is needing so much space)

On nagios I have:

51 Hosts
363 Services

I took a look at your profile, from your XI home page can you click 'nagiosadmin' up top - what do you have your Email Address set to? It should look similar to this -

It does not look like you are a contact on the hosts / services. Let's see what happens if we change the nagiosadmin email to yours.

Navigate to Core Config Manager -> Contacts -> nagiosadmin -> change the email address from nagios@localhost to your personal email.

Are you receiving notifications now?

I did that, but still notifications unfortunately..

Are you seeing anything under Home --> Incident Management --> Notifications?

Yes.

Can you login as root on the Xi server and run a tail om the maillog file like below?

Code: Select all

tail -f /var/log/maillog

Then in the XI GUI, go to Home > Service Details, open a service with the nagiosadmin setup as a contact.
Click on the Advanced Tab and then Send a Custom Notification.

Then post the output of the tail command here so we can see if there are any errors.
