HomeDatabaseMysql Tutorial 【荐】用iopp代替iotop

1、为什么推荐 iopp iotop 对内核及python版本都有一定要求,有时候无法用上,这时候就可以使用iopp作为替代方案。在有些情况下可能无法顺利使用iotop,这时候就可以选择iopp了。它的作者是Mark Wong,用C开发,代码仅有532行,非常简洁。 iopp的项目地址:h

1、为什么推荐iopp

iotop对内核及python版本都有一定要求,有时候无法用上,这时候就可以使用iopp作为替代方案。在有些情况下可能无法顺利使用iotop,这时候就可以选择iopp了。它的作者是Mark Wong,用C开发,代码仅有532行,非常简洁。

iopp的项目地址:https://github.com/markwkm/iopp

2、安装iopp 下载源码到本地后,执行下面的命令即可完成安装: cmake CMakeLists.txt make && make install #或者指定安装的目标路径到 /usr/bin 下 make install DESTDIR=/usr 3、使用iopp

iopp使用起来非常简便,用法:

iopp [-ci] [-k|-m] [delay [count]]

几个常用参数见下,比较简单,,就不一一解释了:

-c, --command display full command line -h, --help display help -i, --idle hides idle processes -k, --kilobytes display data in kilobytes -m, --megabytes display data in megabytes -u, --human-readable display data in kilo-, mega-, or giga-bytes

iopp输出的结果也比较清晰易懂,简单解释下:

pid 进程ID rchar 预计发生磁盘读的字节数 wchar 预计发生磁盘写的字节数 syscr I/O读次数 syscw I/O写此书 rbytes 真正发生磁盘读的字节数 wbytes 真正发生磁盘写的字节数 cwbytes 因为清空页面缓存而导致没有发生操作的字节数 command 命令行名称 本条目发布于2014/10/12。属于系统运维分类,被贴了 iopp、Linux 标签。作者是yejr 个人PPT分享
