  2. Choose 'Status Overview' or 'Status Summary' from the sidebar

  3. Click on hostgroup name (fionavar in this case)

  4. Click 'Enable notifications for all hosts in this hostgroup'

  5. Click 'Commit'

  6. Now the notifications defined in contacts.cfg and services.cfg will be active (e.g. email, pager on reaching critical status)
