SSL certificate expiration notification

Ignition

Hi,

Does Ignition have in-built feature to send notification email when the gateway SSL certificate is about to expire?

Thanks,
Ajay

No.

Where is this information stored? Is there a way to put a watchdog on certificates expiration dates and have automation send the notifications?
Currently we are doing all this manually.

With scripting, more or less anything is possible. That said, if you're worried about the public webserver certificate, just set up an external ACME client and be done with it:

If you choose not to do that for some reason, you are certainly able to open the Gateway's keystore using scripting, retrieve the certificates, extract the date information, and drive logic from them. Use Java standard library imports if you do.

Thanks @PGriffith .
Can you provide a sample code for how i access gateway's keystore?

I am leaning towards that approach.

No, because I don't have any. You could ask an LLM for how to "open a Java keystore using Java's standard library in Jython", and you might get something useful-ish. Paths and default passwords for the keystore are in the linked blog post above.
