А что все же делать с этими метриками?

The golden rule of metrics is this: any metric you maintain should directly drive action if outside expected bounds.

The reason this is an important rule is:

• Metrics are expensive to set up, so if you don’t use them, you’re wasting effort
• Metrics are expensive to maintain, so if you don’t use them, you’re wasting effort
• A metric that doesn’t drive action is a waste of time
