We do track methane in the atmosphere, that is NOAA's job. Methane in the atmosphere tripled from preindustrial times to 1995 and has started to level off since then. It doesn't look like fracking has lead to a dramatic increase in the release of methane in the atmosphere.
Leveled off? It's at record highs and has continued to increase every single year, it hasn't leveled off at all:

The NOAA tracking global methane has literally nothing to do with tracking methane output from individual wells - which again, we don't do. Moving the goal posts doesn't make you right. We DO actively track emissions from coal fired plants. We DO know that fracking has absolutely increased methane emissions:

That didn't reduce emissions and may have actually increased them.
