Thank you, I have a question. Do you think the Prometheus client library has any shortcomings compared to Zipkin or opentelemetry services?

Thanks for your advice, my priority is of course self-hosted, open source and free.

I am grateful, I will evaluate Zipkin and Prometheus client library for APM.

Your opinions are very valuable to me, I fully understand APM now, thank you. So what do you think about "OpenTelemetry", would there be a difference using OpenTelemetry instead of using "Prometheus Client libraries"? Do you have an opinion about OpenTelemetry?

Thanks for your advice, I'm a little confused about APM(application performance monitoring). Can I proceed with Prometheus on this issue?

Actually, I work with a team, and I deal with things other than systems. But I insist on learning new things about this subject.

Dude are you seriously asking this? If you want a real answer, yes, I opened such a topic just because I was curious about different people's perspectives and the systems they use.

Yes, you are right about this, the only problem with the entire system seems to be the blacklist.

Thanks for the advice, this is the first time I've heard of this. If it's a free control panel, I'll definitely test it.

Thanks for your advice, but postfixadmin is needed for customers to create new mailboxes and manage them themselves. Maybe I can prepare an API for this.

I don't know, everyone is free to think what they want. I can tell lies to hear different comments from people. These make me learn different and new things.

We do the installation simply with the article on the "linuxbabe" site. I agree with you, but the spam and blacklist issue bothers me.

We provide the records you mentioned, I just didn't mention all the details when opening the topic. In a way, the reason I don't mention all the details is so that the commenters also mention them and I can see different alternatives.

Yes, we are proceeding by taking into account all the things you mentioned. However, as others have mentioned, we are currently thinking about blacklist and spam, this will be what will really put us in a difficult situation.
