- internal/analyzer: 纯函数规则引擎
- Finding / Severity / Thresholds / Input / StageMetric / ExecutorMetric
- 3 规则: data_skew (max/min ratio), gc_pressure (GC/CPU ratio),
bottleneck (shuffle read+write GB)
- 严重度阶梯: warning / critical (阈值 ×2)
- Analyze 入口数据驱动 for ... range
- 11 个单测 (3 规则 × normal/warning/critical + 零除防御)
- fetch_spark_metrics: SHS 业务封装, format=summary 触发 analyzer
- fetch_cluster_env: RM /cluster/info + /cluster/metrics 聚合
- analyze_spark_log: RM 日志降级链 + LLM-Ready Prompt 拼装
- prompt 结构: cluster 元信息 + log source + log tail +
heuristic findings + suggested LLM analysis
- findings 是 first-pass filter, LLM 做最终判断
- deps.go: +AnalyzerThresholds
- main.go: 注入 cfg 的 3 个阈值
- 端到端实测: analyze_spark_log 完整 prompt 渲染
完成 11 个 Tool 表面 (list_clusters / spark_submit / 4 RM /
fetch_spark_metrics / fetch_cluster_env / analyze_spark_log /
fetch_url / upload_file)
