Integrate Prometheus endpoints with Grafana for better monitoring
Currently some Cacti plugins support some metric management on Prometheus. Example: Ethereum connector, Fabric connector and many more. See an example on how to instantiate prometheus here, define metrics, and to update metrics. We should also explore using OpenTelemetry to replace or complement Prometheus.
Requirements: 1- Explore OpenTelemetry as a technical solution for the list of metrics below. 1 - In order to monitor SATP-Hermes effectively, we need to add support for Prometheus, by defining the following metrics (and tracking them in the corresponding code): -number of supported assets -total number of successful transactions -total number of failed transactions -successful transactions per SATP phase -failed transactions per SATP phase -total peer gateways -total number of sessions -number of sessions with each gateway -total value transferred -value transferred per gateway -number of blockchain transactions done successfully -number of failed blockchain transactions -amount of blockchain transaction fees paid -track transaction IDs (hashes) for every blockchain transaction for later inspection
-number of crashes -number of recoveries -average time to recovery -average time to crash -number of rollbacks
2- SATP-Hermes should define an endpoint that exposes these metrics
3- Use this endpoint to instantiate Grafana to visualize relevant metrics. See this example.
