Satellite self observability dashboard

SkyWalking Satellite collects and exports metrics in Prometheus format and SkyWalking metrics service protobuffer format for consuming, it also provides a dashboard to visualize the Satellite metrics.

Data flow

1. SkyWalking Satellite collects metrics data internally and pushes the metrics to SkyWalking OAP.
2. The SkyWalking OAP Server parses the expression with MAL to filter/calculate/aggregate and store the results.

Set up

1. Set up SkyWalking Satellite Telemetry Exporter.
2. Config SkyWalking OpenTelemetry receiver.

Self observability monitoring

Self observability monitoring provides monitoring of the status and resources of the OAP server itself. oap-server is a Service in OAP, and land on the Layer: SO11Y_OAP.
