(sorry if this has been answered before, tried searching but didn’t find anything)
i just got my pool up and working and want to setup an alert showing days to expiration, for KES key, so i can regenerate a certificate. i would like to setup an email alert if possible…which is easy (the email part)…but i am having difficulty calculating days to expire.
i would prefer shell commands…that way i would understand it better. i know using grafana/prometheus can do this which i plan to setup in the near future.
