最近很多朋友反馈之前开发的 myperf 工具自从增加了 snap 和 report 两个功能升级之后使用起来比以前复杂了,不仅参数选项增加了,还多了一个配置文件,而且还要创建数据库,不是很明白如何使用了。 为了让大家使用起来更方便容易,这里做一个简单的介绍。

最近很多朋友反馈之前开发的 myperf 工具自从增加了 snap 和 report 两个功能升级之后使用起来比以前复杂了,不仅参数选项增加了,还多了一个配置文件,而且还要创建数据库,不是很明白如何使用了。

为了让大家使用起来更方便容易,这里做一个简单的介绍。

  • 文件组成
    1. myperf
      myperf工具主程序,可执行python文件
    2. myperf.cnf
      myperf工具的配置文件,用来存放各种配置项以减少命令行输入
    3. myperf.sql
      myperf工具用来存放性能数据的Schema结构创建文件,如果需要使用snap和report功能,就必须要通过此文件创建好Schema用来存放性能数据。当然,如果一直只是使用top模式,那就不需要使用了
  • 功能组成
    1. top
      类似于Linux/Unix 下最常用最基本的性能查看工具 top 类似,实时刷新展示数据库中的各项核心性能指标信息
    2. snap
      收集数据库当前各项性能状态数据并存储在数据库中,用于性能分析调优,类似于 Oracle 的 Statspack 的 snapshot功能,目前收集的信息主要是 global status,如果是 MySQL5.5,还会手机Performance Schema 中的部分信息
    3. report
      和上面的snap是相辅相成的,主要是对snap存储的性能数据进行分析,获得性能报告,类似于 Oracle 的 Statspack 的 report 功能。当然,由于数据来源有限,和 Oracle Statspack 相比,还有很大的差距

由于配置文件对于程序运行比较重要,所以这里对配置文件再单独介绍一下。myperf 配置文件模仿 MySQL 的配置文件,也将配置项进行了分组,目前的3个分组分别如下:

  • main
    用来配置与数据库连接无关的全局控制参数,如interval,mode,event,session等
  • source
    用来配置被监控的源数据库的连接信息
  • target
    用来配置存放监控数据的目标数据库连接信息,由于需要存储性能数据,所以这里的配置中还会有一个用来指定存放性能数据的database的参数项

最后,有个好消息宣布,那就是 myperf 迎来了第一位合作者 Leopku,@Leopku

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
