Remember what it was like to drive without a GPS? Sure, it’s possible, but a good GPS takes it to a whole new level. Need gas? A Denny’s Grand Slam? A detour around traffic? You’ve got it! And when the kids start asking “how much longer” you have a precise answer! Old-school server metrics are like the gauges in your car: They show what’s happening now and can be useful to the driver, but a lot of questions are left un-answered. This is where application performance monitoring comes in: Rather than just checking server stats, APM gives credible, actionable, and user-focused answers about the state of your systems.
