Previously, the "Event overview" section of HTML email notifications always showed the host's IP address ("Address") and the monitoring site ("Site"), regardless of the notification rule "HTML email parameters".
This caused several inconsistencies:
- The site was shown twice when the "Site ID" option was enabled (once in the event overview and once in the additional details).
- Enabling "IP address of hosts" produced an empty "Additional details" section while the address was still shown in the event overview.
- Both fields were displayed even when neither option was selected.
The "Address" and "Site" rows are now shown only when "IP address of hosts" respectively "Site ID" are enabled in the notification rule, matching the behavior of earlier versions.
Note: Notification rules that do not enable these options will no longer show the address and site in the event overview. If you want to keep them, enable the corresponding option in the "HTML email parameters" of your notification rule.
