There is still something missing for me as a practising DBA. Imagine I face hundreds of servers and I have to see all of them from a particular perspective. You’ll say – “easy, any monitoring tool today has it” and you will be mostly right. Imagine I want to monitor things that make sense to me and to me alone. You’ll say, again – “easy, most of the monitoring tools today have this capability” and almost certainly you will be quite right again. Now, imagine I want to be able to investigate events retrospectively by inspecting every single metric MDA has to offer me in case I miss the fun of being there where things happen? You’ll say – “well, bro, some of the monitoring tools can show you some of the waits and stats back historically, but usually you’ll have to rely on your own MDA collections” and you will be quite right again.
