Research direction

Reproduce the issue with the tiup playground v5.2.0 command and the cdc cli changefeed setup, then open the Grafana TiCDC monitor panel and inspect the missing Server metrics. Trace the playground deployment and monitoring configuration mentioned by those entry points. Done means the Server panel displays metrics such as CPU and file-descriptor data for the TiCDC instance.
