Application monitoring — from requirements to tools, not the other way around [rus]
It may be that I just became old and grumpy, but it bothers me tremendously when someone starts to implement the tools without a clear understanding of what the initial requirements are.
When we talk about monitoring, especially for the web apps, a lot of folks will start thinking something like "I will call some dedicated endpoint and in that way, I will determine the current health state of my application". That is definitely a good starting point, but this is only the beginning.
In my session, I will talk more about the observability quality attribute of the system, different monitoring models that can be implemented with different tools, SLA calculation, and a lot of other important stuff that you need to be concern about before your application will go live.
