Hello,

Our initial rollout of NagiosXI had our nagiosadmin user/contact have Notifications disabled. We continued adding hosts with the

Code: Select all

notifications_enabled           0

set. We are currently running Nagios XI 5.2.3 but these machines started at 5R1.0 with RHEL 6 64 latest updates.

We are now ready to start enabling notifications. We changed

Code: Select all

notifications_enabled

to 1 on all hosts/services and also checked Enable Notifications in the Admin area for the nagiosadmin user. It is not getting notifications nor custom notifications, but we are able to send test emails from the Manage Users page and Mail Settings. The Event Log shows notifications sent but /var/log/maillog does not show messages being sent.

Other users/contacts that we have created are getting notifications for their services, just not the nagiosadmin. Those are in /var/log/maillog along with our test emails from the Manage Users page and Mail Settings.

We looked into the CCM for the nagiosadmin contact (mapped to the nagiosadmin user) and did find that the email definition was set to nagios@localhost where the user was set to a regular email. We changed that setting in the contact to be consistent with the user but still no notifications.

I also noticed the nagiosadmin contact specifies notification commands where the other contacts do not so I removed those to make it consistent with the other contacts and still no notifications. I later found out that the Nagios Core (main) Configuration in the CCM has those set as the global event handler:

Code: Select all

# GLOBAL EVENT HANDLERS
global_host_event_handler=xi_host_event_handler
global_service_event_handler=xi_service_event_handler

So what we have done is pretty much change the contact from this:

Code: Select all

define contact {
	contact_name                  		nagiosadmin
	alias                         		Nagios Administrator
	host_notification_period      		nagiosadmin_notification_times
	service_notification_period   		nagiosadmin_notification_times
	host_notification_options     		d,u,r,f,s
	service_notification_options  		w,u,c,r,f,s
	host_notification_commands    		xi_host_notification_handler
	service_notification_commands 		xi_service_notification_handler
	email                         		nagios@localhost
	use                           		xi_contact_generic
	}

...to this:

Code: Select all

define contact {
	contact_name                  		nagiosadmin
	alias                         		Nagios Administrator
	host_notification_period      		nagiosadmin_notification_times
	service_notification_period   		nagiosadmin_notification_times
	host_notification_options     		d,u,r,f,s,
	service_notification_options  		w,u,c,r,f,s,
	email                         		[email protected]
	use                           		xi_contact_generic
	}

Any help on this would be appreciated.

Are you using SMTP or Sendmail for this? The maillog will only show sendmail logs.

We are using sendmail.

Can you send a "test" email logged in as nagiosadmin user?

Click on the "nagiosadmin" username in the upper-right corner, then click on the "Send Test Notifications" on the left (under the "Notification Options"), and click on "Send Test Notifications". Check to see if you received this test email. Also, check the mail log:

Code: Select all

tail -100 /var/log/maillog

That went through and is listed in /var/log/maillog however it is not in the event log.

Additionally, I go to a host and send a custom notification from the Advanced tab. I get a notice in the event log, but no log entry in /var/log/maillog

If you received the "test" notification email, next thing to do would be to test "custom" and actual notifications. Go to Home->Host Detail->localhost->Advanced. Make sure you see a green dot next to "Notifications" under "Host Attributes".

1. Click on "Send Custom Notification", select "Forced", type a comment, and click "Submit"

2. Under the "Advanced" tab, click on the "Disable" action button next to the "Active Checks" to temporarily disable them. Click on the "Submit Passive Check Result", select "Down" from the "Check Result" drop-down menu, type something in the "Check Output" field, and click "Submit". Don't forget to enable active checks for "localhost" after you are done.

3. Go to Home->Notifications and show us a screenshot of this page.

4. Also, run the following command, and show the output in code wraps.

Code: Select all

tail -100 /var/log/maillog

Note: I am assuming that nagiosadmin is added as a monitoring contact to all of your hosts/services, and you haven't removed it from "localhost". You can test this with any other host. This is just an example.

lmiltchev, you know, I don't think anyone is a contact for localhost. Is that significant?

Go in to Core Config Manager > Contacts and edit the nagiosadmin contact.
Go to the Alert Settings tab and enable the Host and Service Notifications.
Save and apply the configuration. That should fix it for you.

Also, you can review this document for configuring Notifications in XI.

Apologies for not getting back to this sooner. We performed a work around by changing the notification commands to "notify-*-by-email" from "xi_*_notification_handler" on service and hosts.

This can be closed.
