From my experience, yes.

Receviced email from cloudflare about SSL certificate observed issuance

Greetings, Thank you for asking. It’s related to the notification for the zone owner about re-issuing the Cloudflare’s Universal SSL / Backup SSL / some other SSL certificate as it seems to me Some kind of a monitoring tool, helpful in hands and cases to detect possible misissued certificates which might cause issue to your users and visitors. If it was the one at Cloudflare, it might be due to the: Universal SSL Backup SSL Or the SSL if you’re using Advanced Certificate Manager …

I dont know in the email it alwayes say issuance validity period is one month, in the SSL manager it say one year

This is Certificate Transparency monitoring.

It allows you to monitor certificates that are issued for your domain and, normally, Cloudflare doesn’t send notifications about certificates it issues for itself.

Do check what those certificates are, because if you haven’t manually issued them or have no services who should do so, it might be a bad actor or some forgotten service somewhere.

TLDR, pay attention to those notifications.

I dont know I tried to contact CF support a bot replaied to ask the community and marked solved !! I only bought the domain from CF dont know what to do

It’s definitely not an issue with Cloudflare, no one here, nor in Support can help you figure that out.

You need to search the web about that, look at what it has been issued and investigate.

In fact this post in community seems answer my question

I've installed Cloudflare but it turns out to be Google Trust Services SSL

I’ve moved to Cloudflare but it turns out that my website has a SSL Certificate from Google Trust Services which is going to expire in a few months, I’m not sure what to do if it’ll expire. Also: I’ve 2 local internet connections and on the first one SSL is working while on the second one, It’s not and it’s been a whole day. It shows Cloudflare Certificate but also gives a Error, Certificate is not valid.

and this

I dont Recognize the issuance of this certificate and someone has used this certificate to access my website

Someone has used a fake SSL certificate to gain acces into my Account please help how I can get help the certificate to be revoked

That is a different thing, though.

You asked for “what are these CT monitoring email I am receiving”.
I know that Cloudflare now issues certificates from DigiCert, Let’s Encrypt and Google Trust Services. Those are normally not sent in CT emails from Cloudflare, excluding some of the certs from Cloudflare services that are available (e.g. Pages, etc.)
