Go Agent self observability dashboard

SkyWalking go agent reports its metrics using Meter APIS to measure tracing performance. it also provides a dashboard to visualize the agent metrics.

Data flow

  1. SkyWalking go agent reports metrics data internally and automatically.
  2. SkyWalking OAP receives these meters through native protocols.
  3. The SkyWalking OAP Server parses the expression with MAL to filter/calculate/aggregate and store the results.
