Ability to choose the SSL expiry window#80

At the moment we receive notifications from UptimeRobot when an SSL certificate is 14 days away from expiring. The problem is that our server automatically renews the SSL certificate 12 days before expiry. So we always ignore the notifications from UptimeRobot. However, if we could choose the number of days until expiry where we want to be notified, that would make that feature very useful. For example, I would want to know if a certificate was expiring in 8 days - because that would mean the auto-renewal didn’t work. Other people might want a 5 day timeframe. Who knows. If we could choose our own window for the number of days, that would be great.

Uptime Robot just notified me when we had 30 days before expiry. Of course that’s about the time a lot of ACME tools renew certificates (3 month certificate, renew when 1 month remaining). When investigating the alert, my server had already renewed the cert.

Any update on this feature request could be really usefull, as also mentioned earlier LetsEncrypt hits the default, I would e.g. only want an alert if less than e.g. 2 days or 5 days so standard alert 5 days before and maybe if only one day left I would like a call.

We are continually frustrated by notifications of SSL expiry on THE SAME DAY the certificate is automatically renewed by acme.sh/LetsEncrypt. An unnecessary waste of our time and SMS credits. If the first alert interval could simply be changed to 28 days before expiry instead of 30 days, problem solved (with no downside).

Agree with this. We were getting alerts almost daily for certificates that renewed that same day.
It wastes time checking each one.

We had to turn off the check in Uptime Robot and use a different tool to monitor certificates.

And of course, the next number in this series?
7, 14, >>>28<<< NOT 30!

If you don’t want to implement this simple fix, you could at least give us an API method to turn it off, so we don’t have to manually edit every monitor. editMonitor allows you to edit basically every field in a monitor EXCEPT the ssl expiry notifications. It even lets you edit domain expiry notifications, which are in BETA.

Any news on this issue ?
Your first alert at 30 days is the same as the default cert-manager renew interval. We should be alerted only if the auto-renew does not work, this means at less than 30 days (and this can be less depending on the configuration). So the customization of this delay is really needed to not get false positives.
Also, a domain or certificate expiration in 30/14/7 days does not need to send a notification during the night.
We should be able to use another alert contact for domains/certificate expiration, to allow us to not trigger oncall team for this.
Also, in the monitor list, the monitor is green, and the certificate/domain expiration event is missing in the latest events list. This does not help to understand why we are waked up.
As this suggestion is two years old, we will probably migrate to another monitoring tool

Need option to select number of days before expiry of certificate notification

This becomes more important now as Cloudflare uses Google Trust besides Letsencrypt. We have a lot of false positives.
