So that test worked...I was testing it by turning the server off and waiting for the message to go...so why wouldn't that be working.

Update - tests are only working when I use the Forced option.

Hi rpearson,

Making progress, glad to see that's getting through. For the user account that you are using, let's make sure the preferences are not overriding the configurations. Click on the username in the upper right-hand of the screen and select Notification Preferences. Is everything enabled?

Next, let's force a hard down state on a host and collect some log output. Enable phpmailer logging in the Email Settings (Admin > System Config > Email Settings

Run the following tail command and then leave it running.

Code: Select all

tail -F /var/log/maillog /usr/local/nagiosxi/tmp/phpmailer.log /usr/local/nagiosxi/var/eventman.log /usr/local/nagios/var/nagios.log

Then go to Home > Details > Host Status:
- Find the Host and click on it
- Click the + tab (Advanced)
- Click the "Submit passive check result" link
- Select the Check Result, choose DOWN and type in some text for the Check Output
- Click the Submit button

Make sure the state type is HARD Down to send the notification, you should see the notification execute in the nagios.log.

Then paste the full output from the tail command into the thread. Thanks, Benjamin

Hi @rpearson,

Of note I am trying to get emails to go to a Contact and not a normal user - although emails are not going to normal users eithe

For SMTP mail setup, there is another step to configure Contacts to use the SMTP notification handlers. We have setup instructions in the following guide, please follow that to configure this contact.

Configuring Core Contacts to Use Nagios XI PHPMailer SMTP Settings

Also, double check the contact settings on backupexec, I'm not seeing a 'Core" contact assigned to this host object as well nothing in the admins contact group.

Code: Select all

define host {
	host_name	backupexec
	alias	backupexec
	address	backupexec.krellinst.org
	parents	sw-server
	check_period	xi_timeperiod_24x7
	check_command	check_xi_host_ping!3000.0!80%!5000.0!100%
	contact_groups	admins
	notification_period	xi_timeperiod_24x7
	initial_state	o
	importance	0
	check_interval	5.000000
	retry_interval	1.000000
	max_check_attempts	5
	active_checks_enabled	1
	passive_checks_enabled	1
	obsess	1
	event_handler_enabled	1
	low_flap_threshold	0.000000
	high_flap_threshold	0.000000
	flap_detection_enabled	1
	flap_detection_options	a
	freshness_threshold	0
	check_freshness	0
	notification_options	d,u
	notifications_enabled	1
	notification_interval	60.000000
	first_notification_delay	3.000000
	stalking_options	u
	process_perf_data	1
	icon_image	win_server.png
	statusmap_image	win_server.png
	retain_status_information	1
	retain_nonstatus_information	1
	_XIWIZARD	ncpa
	}
# The Admins contact group.
	define contactgroup {
	contactgroup_name	admins
	alias	Nagios Administrators
	}

Please try to configure the Contact required to use the notification handlers in the guide, add this person as a contact to backupexec, and then run the notification tests once more and let me know if the issue is resolved.

Best Regards,
Benjamin

Still no luck. The email goes to IT_TXT and IT Notify if I use the "Forced" option. Without it no emails. What would it cost me to just get an actual support session. I feel like this probably would be resolved rather quickly with a screen share. Otherwise do you have any more ideas? I have redone my profile and will PM it to you. I really need to get this resolved quickly.

Hi,

The configurations look good, and since you are receiving notifications when you force a HARD down, that means it's working from our tests, so it's not an issue with the mail server or email settings.

During normal operations, are you sure the host is down and notifying? From the reporting menu, can you run a State History report on the host object to determine when it went HARD down, and then compare this with the Notification Report, over the same period of time.

Additionally, if it did go down without sending the proper notification, I'd like to review the nagios log from that day, they are located in the following directory.

Code: Select all

/usr/local/nagios/var/archives

The logs are archived once a day, so if it says 5-2-2021, the data in the log would be from 5-1-2021.

Thanks,
Benjamin

It is not emailing when it is a HARD down. It only emails when I click the "Force" check box. The machine definitely goes down I wait longer then necessary and our Nagios Core install on a separate server is alerting to the down. I will look into the logs and upload them later tonight.

PM'd you the last few days of logs.

Hi @rpearson,

Thanks for sending over the logs files. I search through all the files that particular hosts and all the notifications on that host. I'm not seeing any entries in the log results showing the host going down, so that would explain why the notification was not sent.

Additionally, all the corresponding notifications for the host are for a Custom Notification. I've sent the output files back to you in a Private Message so you can review the data.

I would recommend scheduling a State History Report on this host, so we can determine if it goes down, whether the notation was sent or not going forward.

Regards,
Benjamin
