The service summary and details have been enhanced to provide more information and a better user experience.

The host to test, and the port are now included in the service details to provide a better overview of the monitored endpoint.

Response time is no longer provided in the summary and has been moved to the details as a fixed item, only appearing in the summary if it triggers an alert. This provides a more concise summary while keeping this important information available in the details. In addition, the configured thresholds now appear in the output when an alert is triggered.

Subject Common Name (CN) now always appears as a fixed entry in the summary and details.

The issuer common name (CN) now always appears as a fixed item in the details.

Previously, both the number of days remaining until certificate expires and the expiry date were provided in the summary and details. The certificate validity expiration date (notAfter date) is no longer provided in the summary and details, and only the number of days remaining until expiry is provided. This gives a more concise output and is now consistent with the output of the httpv2 service.

Previously, if an alert was triggered,the output was only displayed in the summary. For a more consistent experience, the information now appears in both the summary and the details.
