Explore the correlation of metrics, traces, and logs using Grafana.
The metrics dashboard currently uses metric labels from Dubbo Java and should also support those from Dubbo Go.
Visualize logs in the Dubbo Admin console.
Enable correlation among metrics, traces, and logs.

Start by reviewing the Grafana-based metrics dashboard and the Dubbo Admin console areas that handle metrics, traces, and logs. Compare the existing Dubbo Java metric labels with Dubbo Go labels, then define how log visualization and cross-panel correlation should work. Done means both label formats are supported and the three signals can be correlated in the console.
