> [@hauleth](#): > > And please, could we stop promoting that abomination of library called `exometer` ? It sends shivers down my spine on just mention. Not only it was hellhole to compile it with Mix it also is highly outdated (really, no metric tags in 2019?). I’ve never used exometer so I couldn’t tell, but calling a library an “abomination” isn’t the right way to go or talk about open source libraries. People took care and time to build it offering it to you for free - nobody forces you to use it. You could even improve it. You have your reasons for not using it, that’s fine but you don’t have to resort to insults. That’s what contributes to burnout for maintainers & others. Also that’s really not something I want to see as a tone in the community as it also keeps people away from open source, as they are often afraid of that exact thing happening to them. Never mind that the library is mentioned positively in a book (again [Adopting Elixir](https://pragprog.com/book/tvmelixir/adopting-elixir)) written by people respected by lots of us which was published about a year ago and where one of the authors is a lead developer at a big elixir company (bleacher report) using exometer apparently happily (otherwise I doubt he’d have included it in the book). Might not work for you, but might work for others. --- _[View the full topic](https://forum.elixirforum.com/t/performance-and-analysis-tools/21192)._
