Reset service notification status to configuration defaults?

[lemonflash]

Running Nagios® Core™ 3.4.1 on RHEL5.

I have a number of hostgroups in my Nagios configuration that at some point, had notification for all their services disabled via the Nagios interface ("Disable notifications for all services in this hostgroup").

I have the configuration files set up so that some services on each host are enabled and other services disabled. I could go into the interface and "Enable notifications for all services in this hostgroup", but this would override my preferences set in the Nagios configuration files.

Is there a way to clear the notification preferences set by the web interface and reset the notifications back to what is set in the configuration files? (I'm hoping this can be done by removing a file and allowing Nagios to re-read the configuration file preferences.)

Thanks for your help.

You might be able to remove your .../nagios/var/retention.dat file and restart Nagios.
