Proposed Solution:
New Notification Variables:

Add a new variable, {{CERT_EXP_DATE}}, that represents the certificate expiration date.
Add another variable, {{CERT_EXP_DAYS_REMAINING}}, to include the number of days until the certificate expires.
Customizable Alerts for Certificate Expiration:

🏷️ Feature Request Type

Certificate expiry

🔖 Feature description

Allow users to configure notifications for certificate expiration:
Example: Notify 60, 30, 15, and 5 days before the expiration date.
Make this configurable for all monitors, so users don’t have to set it manually for each monitor.
Email Example: Notifications for certificate expiration should include:

Monitor Name (e.g., DonateFood-Prod).
Certificate Name/Hostname (e.g., dsnydonate.nyc.gov).
Expiration Date (e.g., 2025-10-24).
Days Remaining (e.g., 340 days remaining)

Example Email
Subject: Certificate Expiration Alert: DonateFood-Prod
Body:

• Monitor: DonateFood-Prod
• Certificate Hostname: dsnydonate.nyc.gov
• Expiration Date: 2025-10-24
• Days Remaining: 30 days
  Global Alert Configuration for Certificate Expiry:

✔️ Solution

Add a global configuration option where users can:
Set thresholds for alerts (e.g., notify at 60, 30, 15 days before expiry).
Automatically apply these thresholds to all HTTPS monitors.

I think this is already there. At least for the portion to globally set alerting/notification thresholds for certificate expiration. Have you looked in Settings > Notifications > TLS Certificate Expiry ? Then, on an individual monitor you tick "Certificate Expiry Notification" (and other options on that subject as you see fit) and it will inherit the alerting mechanism.

hi louis, This is what I meant regarding certificate alerts. Currently, when I set up an alert that applies to all my monitors, I also have the certificate expiry notification checked for each monitor. However, when I receive the alerts, this is what happens: I get a message for the up/down status, but the subject is created using the alert's friendly name, which I set up. What I’m trying to say is that we need separate alerts—one dedicated to certificate expiration and another for the up/down status. For the certificate alert, it should allow me to configure notifications for 30, 60, or 90 days prior to expiration. Let me know your thoughts on this.
