Thanks for the suggestion Framirez, we had this discussion internally as well. Supporting GoLang will be a good addition.
As an open community question, would like to know how many are using Go it in production for micro services/ applications etc.. Feedback from the community will help us prioritise.
BTW, we have recently released Node.js agent for APM and its in public beta. Anyone wanting to try it out can do so. Login to the portal -> APM tab -> you will find Nodejs and its installation steps.
