list_server_metrics

List the persisted server-telemetry samples captured for one load run — the data behind the Load view's Server metrics section. While a load run executes, an installed telemetry agent samples the target server(s) (CPU / memory / sessions + any custom gauges) and TestVibe stores them against the run. Unlike get_live_servers, these survive long after the run finishes.

extra is the agent envelope — custom gauges plus server-identity meta (legacy agents may store the bare gauges object).
