Redis Key — [`slot_wallet/app/service/RedisKeyManagerService.php`](slot_wallet/app/service/RedisKeyManagerService.php)\n\n新增 3 个常量（与现有 `PROMETHEUS_*` 命名一致）：\n\n- `PROMETHEUS_HTTP_REQUEST_DURATION_BUCKETS` → `prometheus:http:duration:buckets`\n- `PROMETHEUS_HTTP_REQUEST_DURATION_SUM` → `prometheus:http:duration:sum`\n- `PROMETHEUS_HTTP_REQUEST_DURATION_COUNT` → `prometheus:http:duration:count`\n\n### 2. 记录耗时 — [`slot_wallet/app/service/PrometheusService.php`](slot_wallet/app/service/PrometheusService.php)\n\n新增 `recordHttpRequestDuration(string $method, string $route, int $status, float $durationSeconds)`：\n\n- field 仍用 `json_encode` 存 labels（bucket 额外带 `le`）\n- `_bucket` / `_count`：`Redis::hIncrBy(..., 1)`\n- `_sum`：`Redis::hIncrByFloat(..., $durationSeconds)`（避免整数毫秒精度损失）\n- 对每个 `le` bucket，若 `$durationSeconds <= le` 则递增；最后递增 `+Inf` bucket\n- 抽取私有方法 `buildHttpRequestLabels()`，供 `recordHttpRequest` 与 duration 复用，避免重复 JSON 拼装\n\n扩展 `render()`，在现有 counter 之后输出：\n\n```text\n# HELP app_http_request_duration_seconds HTTP request latency in seconds.\n# TYPE app_http_request_duration_seconds histogram\napp_http_request_duration_seconds_bucket{...,le=\"0.1\"} N\n...\napp_http_request_duration_seconds_sum{...} X.XXX\napp_http_request_duration_seconds_count{...} N\n```\n\n### 3. 中间件计时 — [`slot_wallet/app/middleware/PrometheusMiddleware.php`](slot_wallet/app/middleware/PrometheusMiddleware.php)\n\n在 `process()` 开头 `$startedAt = microtime(true)`，`finally` 中：\n\n```php\n$durationSeconds = microtime(true) - $startedAt;\nPrometheusService::recordHttpRequestDuration($method, $route, $status, $durationSeconds);\n```\n\n优化：将 `resolveRoute()` 结果缓存到局部变量，避免 `finally` 里重复解析；`recordHttpRequest` 与 `recordHttpRequestDuration` 共用同一份 `method/route/status`。\n\n耗时口径：**中间件包裹的完整 handler 执行时间**（含业务逻辑，不含 Prometheus 写 Redis 本身；写在 `finally` 末尾，影响极小）。\n\n---\n\n## Grafana 仪表盘扩展\n\n更新 [`slot_wallet/doc/grafana/app_http_services_dashboard.json`](slot_wallet/doc/grafana/app_http_services_dashboard.json)，在现有请求量面板下方新增一行「Latency」区域（`version` 递增为 3）：\n\n| 面板 | 类型 | PromQL 示例 |\n|------|------|-------------|\n| P50 Latency | stat | `histogram_quantile(0.50, sum by (le) (rate(app_http_request_duration_seconds_bucket{service=\"$service\"}[$__rate_interval])))` |\n| P95 Latency | stat | 同上 `0.95` |\n| P99 Latency | stat | 同上 `0.99` |\n| Avg Latency | stat | `sum(rate(..._sum...)) / sum(rate(..._count...))` |\n| Latency Trend (P50/P95/P99) | timeseries | 三条 quantile 曲线，unit=`s` |\n| Top Slow Routes (P95) | bargauge | `topk(10, histogram_quantile(0.95, sum by (route, le) (rate(..._bucket{service=\"$service\"}[$__range]))))` |\n| Route Latency Details | table | 合并 route 的 P95、Avg、Requests（与现有 Route Request Details 面板并列或扩列） |\n\n所有新面板 `unit` 设为 `s`（秒），threshold 可按业务再调。\n\n---\n\n## 数据流（改后）\n\n```mermaid\nsequenceDiagram\n participant Middleware as PrometheusMiddleware\n participant Redis\n participant Grafana\n\n Middleware->>Middleware: startedAt = microtime(true)\n Middleware->>Middleware: handler()\n Middleware->>Redis: incr requests_total\n Middleware->>Redis: incr duration buckets/sum/count\n Note over Grafana: rate + histogram_quantile\n Grafana->>Grafana: P50/P95/P99/Avg\n```\n\n---\n\n## 验证步骤\n\n1. 本地发若干 HTTP 请求到 slot_wallet（含快/慢接口）。\n2. `curl /metrics`，确认出现 `app_http_request_duration_seconds_bucket/_sum/_count`。\n3. Prometheus scrape 后，在 Grafana 导入更新后的 dashboard JSON，选择 `service=slot_wallet`，确认 P50/P95 有数据。\n4. 跑 `slot-backend-completion-report` 门禁（`php -l` + verify 脚本）。\n\n---\n\n## 注意事项\n\n- **仅改 slot_wallet**（按你的选择）；`slot_console` / `slot_pwa` 结构相同，后续可 copy 同一套改动。\n- Redis Hash 会随 `route × status × bucket` 增长；与现有 `app_http_requests_total` 同一量级，可接受。\n- Histogram 在 Prometheus 侧用 `rate()` + `histogram_quantile()` 算分位；Grafana 查询写法与标准 Prometheus 一致。\n- 无需改 Prometheus scrape 配置（metric 名新增，非替换）。\n","todos":[{"id":"redis-keys","content":"RedisKeyManagerService 增加 duration buckets/sum/count 三个 key 常量"},{"id":"prometheus-service","content":"PrometheusService 实现 recordHttpRequestDuration + render histogram 输出"},{"id":"middleware-timing","content":"PrometheusMiddleware 计时并在 finally 记录 duration"},{"id":"grafana-panels","content":"app_http_services_dashboard.json 增加 P50/P95/P99/Avg 与 route 耗时面板"},{"id":"verify","content":"curl /metrics 验证 + 跑 completion-report 门禁"}]}}]}}

Import 新 JSON，uid 选 app-http-services，Overwrite\n5. 选 service=slot_wallet，看 P50/P95 是否有数\n```\n\n---\n\n## 什么情况算「有问题」\n\n| 现象 | 原因 | 是否严重 |\n|------|------|----------|\n| 新耗时面板 No data | 代码未部署，或该 service 尚无 duration 指标 | 否，预期内 |\n| 原有请求量面板也 No data | 数据源选错，或 Prometheus scrape 异常 | 是，需排查 |\n| 导入后多出一个 dashboard | 没选 Overwrite | 删重复的即可 |\n| 告警失效 | 告警绑在旧 panel 且被覆盖 | 少见，检查一下 |\n\n**总结**：直接替换线上 dashboard **可以**，对现有监控无破坏性；只要**覆盖导入（同 uid）**、**数据源配对**，并**在 slot_wallet 代码上线后再看耗时面板**，就没问题。\n\n[REDACTED]"}]}}

{"role":"assistant","message":{"content":[{"type":"text","text":"Prometheus 本身不会自动发现 Webman 服务，需要你在 **监控机** 的 `prometheus.yml` 里手动加上 scrape target。你们项目里配置文件在：\n\n[`monitor/config/prometheus/prometheus.yml`](monitor/config/prometheus/prometheus.yml)\n\n目前业务指标那段还是注释状态（第 89–94 行），需要改成正式配置。\n\n---\n\n## 1. 确认 slot_user 已暴露 `/metrics`\n\n部署代码并重启 slot_user 后，在 **应用服务器** 上验证：\n\n```bash\ncurl -s http://127.0.0.1:20001/metrics | head\n```\n\n应能看到类似：\n\n```text\napp_http_requests_total{service=\"user\",...}\napp_http_request_duration_seconds_bucket{service=\"user\",...}\n```\n\n本地 `.env` 里 slot_user 端口是 `20001`（`HTTP_LISTEN = http://0.0.0.0:20001`），`service` label 为 `user`。\n\n---\n\n## 2. 改 Prometheus 配置\n\n编辑 `monitor/config/prometheus/prometheus.yml`，在 `scrape_configs` 末尾增加（或取消注释并改成实际地址）：\n\n```yaml\n - job_name: app_metrics\n metrics_path: /metrics\n scrape_interval: 15s\n scrape_timeout: 10s\n static_configs:\n - targets:\n - 172.31.5.131:20001 # slot_user\n - 172.31.5.131:20003 # slot_wallet\n - 172.31.5.131:20004 # slot_console\n - 172.31.5.131:20008 # slot_pwa\n labels:\n env: production\n```\n\n说明：\n\n| 项 | 含义 |\n|---|---|\n| `targets` | **应用服务器内网 IP + 各服务 HTTP 端口**（不是 Prometheus 端口 9090） |\n| `metrics_path` | 固定 `/metrics` |\n| `service` 区分 | 不靠 Prometheus 配置，靠应用里 `config('app.server_name')` 写入指标（user / wallet / console / pwa） |\n\n若服务分布在多台机器，按实际 IP 填写，例如：\n\n```yaml\n - targets:\n - 10.0.1.11:20001 # user @ app-01\n - 10.0.1.11:20003 # wallet @ app-01\n - 10.0.1.12:20004 # console @ app-02\n```\n\n---\n\n## 3. 网络与安全\n\nPrometheus 跑在 **监控服务器**（`monitor` docker-compose），需要能访问应用机的 `20001` 等端口：\n\n1. 应用机安全组 / 防火墙：仅允许 **监控机私网 IP** 访问 `20001`（及 wallet/console/pwa 对应端口）\n2. **不要**把业务端口对公网开放\n3. `/metrics` 无鉴权，靠网络隔离保护（与现有 wallet 等一致）\n\n---\n\n## 4. 重载 Prometheus\n\n监控服务器上（`monitor` 目录）：\n\n```bash\n# 配置已挂载进容器，改文件后 reload 即可\ncurl -X POST http://127.0.0.1:9090/-/reload\n```\n\n或：\n\n```bash\ndocker compose restart prometheus\n```\n\n---\n\n## 5. 验证 scrape 成功\n\n**Prometheus UI** → Status → Targets，找 `app_metrics`，对应 `20001` 应为 **UP**。\n\n或命令行：\n\n```bash\ncurl -s 'http://127.0.0.1:9090/api/v1/targets' | grep -A5 '20001'\n```\n\n查指标是否有数据：\n\n```promql\napp_http_requests_total{service=\"user\"}\napp_http_request_duration_seconds_count{service=\"user\"}\n```\n\n---\n\n## 6. Grafana\n\ndashboard 已支持 multi-service，无需再改 JSON：\n\n1. 导入/使用 `app_http_services_dashboard.json`\n2. 顶部 **Service** 下拉选 `user`\n3. 耗时面板（P50/P95 等）应有数据\n\n---\n\n## 本地 Docker 开发注意\n\n若 Prometheus 在 `monitor` 容器、应用在 `php82` 容器，两者不在同一网络时，`172.31.x` 不适用。可临时用宿主机 IP，例如：\n\n```yaml\n - targets:\n - host.docker.internal:20001\n```\n\n（macOS Docker 支持 `host.docker.internal`；Linux 可能需写宿主机实际 IP。）\n\n---\n\n**总结**：在 [`monitor/config/prometheus/prometheus.yml`](monitor/config/prometheus/prometheus.yml) 增加 `app_metrics` job，target 写 **`应用服务器IP:20001`**，`metrics_path` 为 `/metrics`，reload 后在 Targets 里确认 UP，Grafana 选 `service=user` 即可。\n\n如果你告诉我线上应用机的内网 IP（以及 user 是否和其他服务同机），我可以直接给你一份可粘贴的完整 `prometheus.yml` 片段。\n\n[REDACTED]"}]}}
