One of the challenges in adopting an open-source alternative to popular commercial packages is sorting through the complicated landscape of projects to understand which components you need, which ones play nicely together and exactly which part of a total solution each component covers. This is particularly difficult in the world of observability, where the standard practice is to purchase one comprehensive but pricey package to do it all. OpenAPM makes the open-source selection process for observability tools easier. It displays the current crop of open-source packages classified by component roles, so you can interactively select compatible components. As long as you keep the tool up to date, it should help you navigate through the confusing array of possible tools.
