For those interested in monitoring (and if required, notifications) for their certs we at Certify The Web prototyped some support for other ACME clients to report to our dashboard a while back.
If anyone is interested in trying it out please join the conversation at Renewal monitoring dashboard for Certbot, acme.sh etc - Announcements - Certify The Web - Support Community
[Edit: note this is not CT/issuance monitoring, this is monitoring the attempts of your actual ACME client so you see problems before they matter]
