How Notification works in failover mode.

example: There is a one to one failover for the Nagiosxi server and if one fails or if the nagios node is not able to reach primary XI server and it goes to Secondary XI server and the threshold value is breached for that server and event is generated , so Seconday XI server will send the notification? and after some time if the Nagios noxe is able to reachout the primary and its still in critical state, is primary going to send the notification?
Also would like to understand the notification process and where the data for notification is stored.
Can we use single db for two XI web interfaces?

NagiosXI doesn't have its own builtin HA constructs. Using some crafty event handlers or service dependencies you could achive having 2 active XI instances with only one notifying, but this would create 2x the monitoring load which isn't ideal.

Nagios failures are so few and far between that it's generally acceptable to simply have a standby node that is manually brought online using traditional backup/restore in the event of a primary node failure. There are other documented options:

Regarding a shared mysql database -that is not supported.
