myperf 继 0.1-beta 版发布,可以实时在线显示 MySQL 性能数据并定期刷新之后,最近又增加了计划中的另外两个小功能:

  • 定期收集MySQL数据库的性能数据并存储(snapshot) 由于初衷主要是考虑到多台 MySQL 服务器,所以数据会集中存储到一台集中的 MySQL Server中,并没有保存到自身。当然,以后有可能增加这样的功能。
  • 根据性能数据的snapshot进行分析并生成report记录到文本文件 目前生成的报表还只能生成纯文本方式,不支持保存在数据库中。且只支持生成相邻两个snapshot的报表,暂不支持人工选择某两个snapshot之间的报表。

除了增加这2个功能外,还在原来的基础上增加了一个可选配置文件。主要是为了减少在命令行输入的内容,毕竟很多时候都在重复输入一些参数。当然,不喜欢配置文件方式的同学,选择不使用配置文件,直接将参数全部在命令行中输入。 由于现在 MySQL 5.5 增加了 Performance Schema,所以新版本中也增加了针对 Performance Schema 数据的收集,比如Event wait,File IO 等,只是目前针对这写数据的分析还比较弱,希望后续能加强一些。 源代码、配置文件以及存储snapshot数据所使用的Schema结构文件都放在 Google Code 上了,可以通过SVN工具匿名方式co出来,也欢迎猛击下载试用。 至此,之前设想的基本功能已经完成的差不多了,我的代码写的比较糙,有兴趣进一步完善的同学,欢迎 Gmail 给 sky000,一起维护完善这个小工具。
