New 'overview' tab on the agents dashboard, extending it per the
hive stats page's own summary layout (busiest-agents table + top KPI
row):
- KPI row: active agents, turns, tokens (all types), input, output,
cache-read tokens, cost. All from metrics already flowing into
this dashboard (claude_code.token.usage / claude_code.cost.usage /
claude_code.session.count) plus hyperhive.agent.turn.count, which
the harness already emits but nothing visualized yet.
- Busiest-agents replicated as five sorted bargauge panels (turns,
cost, input, output, cache-read, each by agent) rather than one
literal multi-column table -- this schema (Grafana v2beta1) has no
existing table+merge-transform panel anywhere in this repo to
pattern-match against, and every other panel here follows the
proven sort_desc(...) + bargauge shape already used for
'Cost by subagent name' (panel-43). Trading the exact table layout
for schema I can verify against a working precedent.
- Left out the stats page's 'window' tile -- redundant with the
dashboard's own always-visible time-range picker.
No new instrumentation needed. Structurally verified (valid JSON, no
duplicate panel ids, every panel referenced exactly once in the
layout) but not visually verified -- no local Grafana to render
against.
