TEQ Monitor System consists of three services including Prometheus Oracle DB Exporter, Prometheus, and Grafana. Exporter is the connector to Oracle DB and format the query results to Prometheus-like metrics. Prometheus is a time-series database and periodically controls Exporter to query and collect/store metrics. Grafana uses Prometheus as data source to show the metrics and make it visualized. Grafana is a user-interface with charting and computation built-in. The whole services is configured, managed and handled by Docker-compose.
