Implement Metrics in EDC

[ma3u]

WHAT

The EDC owner need to define the main KPIs to measure the Data Exchange:

1. Number of offered Assets in the catalog
2. Number of contracts per month
3. Unique connections between two BPN
4. Amount of File transfers (incoming, outgoing)

WHY

Data Providers want to create Dashboards to track and audit the data transfer of the EDC.

Positive and negative activities of the Dataspace Protocol describe catalog, contract negotation, transfer process.

HOW

Open Telemetry example on Micrometer/Jaeger scape the REST endpoints only.

We need to implement log messages as Extension for the Tractus-X EDC for time series data (history data) like Grafana as persist log events and visualize this data in dashboard in Prometheus.

Create a branch OpenTelemetry for Tracts-X EDC. We work with pull requests.

Create a Umbrella Helmchart for OpenTelemtry monitoring.
