The way it integrates with our application, that's what I like most about this product! It works as expected in all cases where we need to monitor memory usage; so far there hasn't been anything negative at work for me or my customers using plumBr! Nothing particular from now until then ;-) but if you don´t use monitoring tools such than maybe they are not suitable because other products tendo be more popular among developers nowadays (like NewRelic). We have one server which hosts several applications running different types o services/solutions : webapps - backend apps hosted behind nginx proxy frontend servers serving static resources via NGINX proxies & JWS Server hosting WS / SOAP Endpoints handling XHR requests through NodeJS APIs etc..
