You never saw it coming.

Your monitoring tools have been silent.

But your ride sharing application just broke.

You have a feature that gives users a precise time when to expect their ride to arrive.

Your app calculates this time by pulling data from external sources like Google Maps.

But suddenly, your app starts giving your users inaccurate wait times.

Something is off and you need to find out what it is — fast.

So, you open up your monitoring dashboards.

Server. Application. APM. You check them all out.

They all look clean, but the problem is still there in the product. Your customers are still complaining, and now your business leaders have joined in.
