Observability

Logs

The platform aggregates logs for your application in a buffer of finite size. If you want to persist these you must ship your logs to an external service.

Metrics

The platform can be configured to emit application metrics in standard statsd or prometheus format. To persist these metrics, you must ship them to an external service.

For most backing services, we provide metrics in the GOV.UK PaaS admin tool.

Tracing

The platform adds Zipkin compatible headers to the incoming requests so you can match those with your application's responses.
