You need to instrument your code using some standard library depending on the language the application is written and then you can expose the metrics at /metrics endpoint which can be scraped by prometheus and shown in a Grafana dashboard.

If it's a JVM based app then micrometer is easy to use and exposes some metrics by default.

All other major languages has prometheus client library which can used to instrument code and expose metrics.
