How do I setup e-mail alerts when the treshhold for specific check reaches out to specified max?

Thanks.

Could you describe in detail a little more what you would like to accomplish?

Let's say if my disk usage on the remote monitoring server reaches 90%, I want automatic e-mail notification alert to be sent out.

This should be the default behavior.

One thing to make sure is the the user that is defined to receive notifications has their account setup to send them.

Top right of screen click on username next to "Logged in as: "
Click "Notification Preferences"
Make sure you select "Enable Notifications" & all of the "Notification Types" to receive.

Click "Notification Methods"
make sure you have a method chosen of how to send the messages.

If notifications are enabled, you should be able to receive an alert. Let's say that you are running a disk usage check and your warning and critical levels are already set at 80 and 90.
Go to the: Core Config Manager->Monitoring->Services->Disk Usage (or whatever your check is called)->Alert Settings. Fill in all of the info, for example:

Contacts = nagiosadmin
Notification period = nagiosadmin_notification_times
Notification options = w, c, r
Notification interval = 60
First notification delay = 0
Notifications enabled = on

Click "Save", "Apply Configuration".

Now when your disk usage reaches 80%, you will receive a warning alert; if it is above 90% you will receive a critical alert.

The settings you set under the Core Config Manager (Service Management) will override the template that this service is using. You can also modify the template, but this will affect all of the hosts/services using the same template.

Note: Make sure that notifications are enabled for this particular user:

Configure->More Options->My Account Settings->Notification Options->Notification Preferences->Update Settings

Hope this helps.

When I click on "Send Test Notifications" button it does not send me a test e-mail (I put my work e-mail address to test).
I selected "Enable Notifications" & all of the "Notification Types" to receive e-mail.
Nagios XI is running snmpd service. What am I missing?

What are your setting in Admin -> Manage Email Settings?

General Mail Settings
Mail Method:
* Sendmail
SMTP

Send Mail From: localhost@localdomain

Note: The bullet is selected for "Sendmail"

If that is what you want to use for your mail settings you may want to check To see if you see any errors
