That's a good catch!!! My Bad I didn't checked this. thanks a lot, this sorted my issue.
I am glad I could help!
small query:
How can I change the mail notification updated for 8 hours for all the hosts and services?
host_freshness_check_interval=60 is the same parameter that I need to update for all the services or anything else. please advise. thanks.
Are you talking about modifying the notification_interval?
Service - notification interval
This directive is used to define the number of "time units" to wait before re-notifying a contact that this service is still in a non-OK state. Unless you've changed the interval_length directive from the default value of 60, this number will mean minutes. If you set this value to 0, Nagios will not re-notify contacts about problems for this service - only one problem notification will be sent out.
Parameter name: notification_interval
Required: yes
You can enter "480" in the "Notification interval" filed under "Service Management" for each service (CCM->Services-><your service>->Alert Settings), save and apply configuration.
You could modify "notification_interval" for all hosts/services "in bulk" via the "Bulk Modifications" tool, which is part of
Nagios XI Enterprise Edition. If you don't want to purchase Enterprise, you could just start a free, fully functional 60-day trial, and get the job done.
Hope this helps.
