Front End

WeatherApp

http://localhost:8080

Pressing the weather button generates metrics and correlated logs and traces which are exported to otel-collector. otel-collector then pushes the logs to Loki, the traces to Tempo, and exposes metrics for Prometheus to scrape. Grafana queries Loki, Tempo and Prometheus where the three data types can be correlated and visualised.

Upon entering credentials to log in, skip updating the password with the "skip" button.

go to Dashboards to see a list of compiled community dashboards visualizing various metrics related to components of the system.

App telemetry data in Prometheus, Loki and Tempo can be viewed in the Explore section.
