All applications and the underlying infrastructure produce metrics, logs, and where useful traces as well. These are gathered and prepared by proven open-source tools like Prometheus (metrics), Loki (logs) or Jaeger (traces). Subsequently, these data are centrally visualized in Grafana dashboards. At this point, the user gets an overview of the applications and infrastructure components he is sharing. For a long-term storage of data, additional data bases like InfluxDB can be employed.
