It appears you need to setup DNS correctly which doesn't seem to be in place. The records do exist, but you're not resolving them. http://mxtoolbox.com/SuperTool.aspx?act ... n=toolpage

What host or service name is it?

Please post your /usr/local/nagios/var/objects.cache to go with your response as well, so we can reference your configurations.

Please show us the emails that are arriving 'late' so we can compare it to your configuration.

Do you want to setup the nagiosadmin contact to not forward the emails off the server but read them locally on the server?

If so, you would have to add the nagios hostname to the /etc/hosts file like the example below

Code: Select all

56.72.9.216 Nagios.localdomain
Try that and see if that fixes the delayed emails.

To get the email notifications to send every 3 hours, you would have to edit the Service Check and change the Notification interval to the following.

Code: Select all

notification_interval	180
That will set it to email every 180 minutes (3 Hours).

To set the email notification delay, you will have to add this option to the host or service you want to delay emails for 20 minutes.

Code: Select all

first_notification_delay	20
