Get insights into the performance of your Koa application and cascading middlewares.
AppSignal automatically instruments and monitors middleware response times. In the slow events screen, you can dive in and see where throughput is an issue. Set triggers and alerts for any value on any graph in AppSignal.
AppSignal automatically provides a dashboard that monitors your heap. Set up alerts and get notified through Slack, email, or another channel of your choice when total heap size gets too big.
Inspect duration and throughput per route in easy-to-read charts. Figure out what middleware is performing badly.
To debug any performance problems in your Koa application, click on any peak in a graph, go to a performance issue, and view the event timeline. You'll see a breakdown of the time it takes for each piece of middleware to execute and where you can improve performance.
