Most small teams start by tracking everything they can, and end up looking at nothing. The problem is not the tooling, it is that nobody agreed on which numbers are allowed to change a decision.

A simple test: for each metric, ask what you would do differently if it moved. If the answer is nothing, it is not a metric, it is a dashboard decoration.

The second test is about resolution. A weekly number and a daily number often answer different questions, and mixing them makes both useless. Pick one cadence per metric and keep it.
