One of Stacksight's biggest advantages is that it builds your stack's health profile, aggregating information from a growing number of 3rd-party integrations. We call these "Signals".
Naturally, the more signals you aggregate, the richer your health profile would be. Remember: information is power, so the more information you have, the stronger you'll be!
Signals are usually being collected directly from your stack, so they require you to install some additional plugins or modules, which have a built-in integration to Stacksight.
