7.14 will see a change to how the Uptime TLS certificate rule work from Uptime. With the current implementation, users receive a single alert describing all the certificates that will be expiring or are aging. From 7.14, users will receive a separate alert for each certificate individually.
With the Uptime TLS certificate rule, you can create a rule that notifies you when one or more of your monitors has a TLS certificate expiring within a specified threshold, or when it exceeds an age limit. For more information about how to configure a TLS certificate rule and receive alerts, check out the 7.14 documentation: https://www.elastic.co/guide/en/observability/7.14/tls-certificate-alert.html.
