罗盘

English document

罗盘是一个大数据任务诊断平台,旨在提升用户排查问题效率,降低用户异常任务成本。

其主要功能特性如下:

  • 非侵入式,即时诊断,无需修改已有的调度平台,即可体验诊断效果。
  • 支持多种主流调度平台,例如DolphinScheduler、Airflow或自研等。
  • 支持多版本Spark、Hadoop 2.x和3.x 任务日志诊断和解析。
  • 支持工作流层异常诊断,识别各种失败和基线耗时异常问题。
  • 支持引擎层异常诊断,包含数据倾斜、大表扫描、内存浪费等14种异常类型。
  • 支持各种日志匹配规则编写和异常阈值调整,可自行根据实际场景优化。

罗盘已支持诊断类型概览:

诊断维度 诊断类型 类型说明
失败分析 运行失败 最终运行失败的任务
首次失败 重试次数大于1的成功任务
长期失败 最近10天运行失败的任务
耗时分析 基线时间异常 相对于历史正常结束时间,提前结束或晚点结束的任务
基线耗时异常 相对于历史正常运行时长,运行时间过长或过短的任务
运行耗时长 运行时间超过2小时的任务
报错分析 sql失败 因sql执行问题而导致失败的任务
shuffle失败 因shuffle执行问题而导致失败的任务
内存溢出 因内存溢出问题而导致失败的任务
成本分析 内存浪费 内存使用峰值与总内存占比过低的任务
CPU浪费 driver/executor计算时间与总CPU计算时间占比过低的任务
效率分析 大表扫描 没有限制分区导致扫描行数过多的任务
OOM预警 广播表的累计内存与driver或executor任意一个内存占比过高的任务
数据倾斜 stage中存在task处理的最大数据量远大于中位数的任务
Job耗时异常 job空闲时间与job运行时间占比过高的任务
Stage耗时异常 stage空闲时间与stage运行时间占比过高的任务
Task长尾 stage中存在task最大运行耗时远大于中位数的任务
HDFS卡顿 stage中存在task处理速率过慢的任务
推测执行Task过多 stage中频繁出现task推测执行的任务
全局排序异常 全局排序导致运行耗时过长的任务
