What's a metric you track that doesn't actually tell you anything?

tracked page views for a year before admitting they told me nothing about whether the product worked. Vanity metrics are comfortable they go up and make you feel successful. Meanwhile the numbers that actually mattered, like whether anyone came back without being reminded, I wasn't measuring at all.

The metric wasn't the problem. I was choosing the one that made me feel good instead of the one that told me the truth.

So for those who've cleaned up their dashboards: what did you drop, and what replaced it? And the harder question what number are you still looking at every day that has never once changed a decision you made?
