Using Pingdom's "SSL Certificate Monitoring and Alerting", when the certificate is about to expire, you receive a "DOWN alert" with the following text
Pingdom DOWN alert:
example.org (example.org) is down since 05.03.2022 14:41:39.
Reason: The set SSL certificate expiration threshold has been reached
As not every receipient might know, or have access to see, the configured "expiration threshold", I would like to suggest to add some more info to the "Reason" text - and perhaps also make it a bit more "human friendly". E.g. something
Pingdom DOWN alert:
example.org (example.org) is down since 05.03.2022 14:41:39.
Reason: The SSL certificate will expire in 14 days at March 12th 2022 14:41:02
Would of course also prefer that it didn't arrive with the text and subject "DOWN alert: example.org (example.org) is DOWN", since it makes recipients jump, because they think the site is actually down - until they get to the "Reason". But I don't know if Pingdom's architecture would make it too difficult to change the text to something like "Certificate alert", "SSL certificate warning", or something similar and less alarming?
