### 2026-07-02 P8.4 Long-running Gray Soak and Heartbeat SLO
|
||||
|
||||
目标:
|
||||
|
||||
- 不扩大并发、不做 UI,先把 P8.3 heartbeat 纳入每日 SLO 报告。
|
||||
- 让 23:55 定时日报和手动 `runtime-slo-report.mjs` 都能暴露 running heartbeat 风险。
|
||||
- 为后续 24h all-user gray soak 提供稳定观测字段。
|
||||
|
||||
改动:
|
||||
|
||||
- `scripts/runtime-slo-report.mjs`:
|
||||
- `runtime.toolQueueSlo` 新增 heartbeat 摘要:
|
||||
- `heartbeatMs`
|
||||
- `maxConcurrentRuns`
|
||||
- `statusCounts`
|
||||
- `oldestRunningStartedAt`
|
||||
- `oldestRunningAgeMs`
|
||||
- `oldestRunningHeartbeatAt`
|
||||
- `oldestRunningHeartbeatAgeMs`
|
||||
- `runningWithoutHeartbeatCount`
|
||||
- `latestRunningRun`
|
||||
- failure 条件新增:
|
||||
- `agent_run_heartbeat_stale_<age>`: running heartbeat age 超过阈值。
|
||||
- `agent_run_missing_heartbeat_<count>`: running run 长时间缺失 heartbeat。
|
||||
- Markdown 报告的 Tool Queue 段落展示:
|
||||
- `heartbeatMs`
|
||||
- `oldestRunningHeartbeatAgeMs`
|
||||
- `runningWithoutHeartbeatCount`
|
||||
- `.env.example`:
|
||||
- 记录 `MEMIND_AGENT_RUN_HEARTBEAT_STALE_MS=90000`。
|
||||
- `docs/agent-run-worker-rollout-runbook.md`:
|
||||
- 记录 heartbeat SLO 检查命令和期望字段。
|
||||
|
||||
测试:
|
||||
|
||||
- `node --check scripts/runtime-slo-report.mjs` 通过。
|

|
||||
- `ok=true`
