What do you mean? All modern enterprise analytics/monitoring solutions are going to be able to give you some kind of top-level "request success rate" metric. I assume they mostly just lean into whatever monitoring tooling they have set up. What kind of "calculation" are you imagining here? Like a very specific SRE formula for availability windows or something?

Depending on what part of the system is down, how do you know you even got a request to mark as failed?

You want to start measuring the closet to your users. In most cases that would be some sort of load balancer. I don't think there's much we can do without going to the client side.

It means their SLA bases on non 5xx and connection errors?

I mean that seems like a question to ask an account rep? I'm sure it's also probably not a hard and fast rule for every single customer, hence the ambiguity in the general language.
