Repeated alerts for users migrated from Nagios Core

I have a number of hosts, services and contacts from Nagios Core, recently I migrated them to Nagios Core 5.
Originally it was using "notify-host(service)-by-email" to send email alert, after migration we created users linking with the contacts, and use "xi_host(service)_event_handler" for alerting. Now once there is any alert, users got 2 emails, one sending from xi_host_event_handler and one sending from notify-host-by-email, why does this happen? I can't find anything wrong in configuration indeed.

Are you using sendmail or SMTP?
Can you post the service definition of one for us to take a look at?

Using sendmail locally.
Basically we only see "notify-host-by-email" in template "generic-contact".
But the user getting repeated email is using template "xi_contact_generic" and he actually receiving email one by "notifiy-host-by-email" and one by "xi-host-notification-handler".
Here are an example of the service and contact we are getting double alerts.
Code: Select all
define contact {
name generic-contact
host_notification_period 24x7
service_notification_period 24x7
host_notification_options d,r,f,s
service_notification_options w,c,r,f,s
host_notification_commands notify-host-by-email
service_notification_commands notify-service-by-email
register 0
}
define service {
service_description PING
use generic-net-service
hostgroup_name SHHO
check_command check_ping!200.0,20%!600.0,60%
check_interval 5
retry_interval 1

Do you have an 'XI User' with the same name as the 'Contact'?
This is a good document to take a look at:

Taking a step back for a second.

If it's the ping service you are receiving multiple emails for, is it possible you are receiving one email for the HOST object (which happens to be a ping check) and a SEPARATE email for the Ping service?
Can you paste the contents of the duplicate alerts here so we can compare them please.
Also what is the output of these commands:

Both of the alerts are "host" alert, and they are about 2 minutes apart.
When the host was down, 1st alert received, 2nd alert (repeated) came around 2 minutes later, after the notification interval, 2 alerts again, until the host is back online.
So in our opinion it is something duplicated. But it was OK for Nagios XI users newly created (not imported from core).
Code: Select all
[nagios@nagiosxi cfgprep]$ ipcs -q
