MetricFire add-on: Show Sentry Errors in Annotations
The solution: We can use Sentry to track specific errors that occur on production and Hosted Graphite's Sentry webhook add-on to add annotations to our system performance graphs. This way, we can correlate when a specific error occurs with our system usage spikes. Sentry is an application that alerts you when an app gets an error. It can also alert you to specific mistakes so you can see when and where something broke.
