Nagios doesn't send notifications in order

[xerez]

Hi, I am testing alerts in Nagios, I simulated a critical error and after a recovery. In the GUI, in Notifications is fine:

Code: Select all

hostname	Memory Usage	OK	09-28-2015 10:24:56	nagiosadmin	notify-service-by-email	Virtual Memory: 32% Physical Memory: 58% (<90%) : OK
hostname	Memory Usage	CRITICAL	09-28-2015 10:19:54	nagiosadmin	notify-service-by-email	Virtual Memory: 32% used (3365 MB / 10649 MB) Physical Memory: 58% used (2371 MB / 4096 MB) (>20%) : CRITICAL

But the emails alerts arrived bad, first the recovery, and four minutes later the critical:

Code: Select all

***** Nagios *****

Notification Type: RECOVERY

Service: Memory Usage
Host: hostname

Why does happen it?

This appears perfect to me.

They are using the same notification command so the problem must almost certainly be in your mailing system. Is it possible that your mailing system has some sort of a greylisting functionality that puts a hold on E-mails?

No, but he moment it is working fine again, I don't know what could happen.

Let us know if it pops up again. I'll leave this topic open for now.
