Use Lightstep to monitor your app for performance.
Lightstep offers a way to quickly see how all your services and their operations are performing in one place - the Service Directory view.
Create Streams to view historical span and trace data and monitor your services.
Use Lightstep to monitor service performance after a deployment to catch regressions and other issues quickly.
You can create thresholds on Streams that when crossed, send alerts to everyone that needs to know about it. Thresholds can be set for an error percentile, latency, or operations per second, on any operation within your distributed system.
