I am not sure if HN is for you. These are well known companies in this sphere and barring that a quick Google search would answer these questions but obviously you are just making a reddit style joke post that also has no place here.

I'm semi-serious. I know NewRelic, as we use it at work and it's good. I don't know those other products, so the "explanation" didn't explain anything to me. Comments HN excel (sometimes) at distilling the merits of using these products in a way that press releases that a google search finds really do not.

I'm sorry if you didn't like the terse and flippant way that I expressed that.

Thanks for the vote of confidence, though. I see that your account is less than a month old (hint: click on the user name and you can see the same about me).
