It's kind of like how in a proper team where there is already trust and no micromanagement, everyone continues to do their work and remain productive no matter what, while often in a team where management does not care about ICs and treats them as disposable, and the they only show up for an income, are hourly, or just churn out crap in volume, they're gonna slack off as soon as your back is turned.
It entirely depends on their use, ask the team(s) involved first, and the level of trust. You'll be strung out to hang if your team already doesn't trust you and now you want to throw this "surveillance watchdog garbage" at them.
If your team trusts you as management, you may get some kind of buy-in as to how some graphs may help them work smarter, but at that point it's likely something they don't _need_, and if you start forcing value judgements off that data there's a high chance they're going to resent you for it.
