SSL Cert expiration alerts for sub-Domains

Feature Request

We have public and private API checks that (by default) pull the “cert days to expiration” for the underlying site/API endpoint.

but most API checks that we test, have a preceding sub-domain and it would be great to have Checkly report the “cert days to expiration” for the sub-domains too.

for eg:

www.mysite.com // 35 days to expire

www.sub.mysite.com // also reports 35 days to expire even though sub.mysite cert is good for 90 days.

    Hi!

    You can now create a separate SSL monitor for each subdomain. Set the exact hostname, such as www.sub.mysite.com, and Checkly will report and alert on the certificate served for that hostname.

    Hi!

    Thanks for the feedback! We’ve discussed a dedicated SSL check type, and this seems like it would fit there.

    Cheers,
