Analyze reshaped metrics from TiDB cluster Prometheus and give some advice about anomalies and correlation.

背景

当用户利用 metrics 去定位性能问题或这分析集群行为时,如下问题会影响定位和分析的效率。

  1. 需要有很充分的背景知识,才能理解 metrics 本身的现实含义以及 metrics 之间的关联关系,进而利用其反映的信息来帮助定位性能问题和理解集群行为。
  2. 有了背景知识并理解 metrics 的现实含义后。用户按照自己的思路去观察 metrics 或者对比不同的 metrics 时,在 UI 界面上也还会涉及到很多人工的操作,导致效率不高。

项目介绍

metrics 本身都属于时序数据。时序数据本身有一些共有的性质和通用的分析手段,这些分析手段本身不依赖任何背景知识。项目的目标是通过时序数据的分析手段,在不依赖任何背景知识的前提下帮助用户分析出 metrics 中表现出的特性。 我们选择 TiDB Read and Write Performance 面板涉及的 metrics 做为分析的数据,最终回答用户如下两个问题:

  1. 其中是否有异常的 metrics?
  2. 哪些 metrics 是与异常 metrics 相关的?

项目设计
