20 Useful Commands of ‘Sysstat’ Utilities (mpstat, pidstat, iostat and sar) for Linux Performance Monitoring
|
||||
================================================================================
|
||||
In our last article, we have learned about installing and upgrading the **sysstat** package and understanding briefly about the utilities which comes with the package.

‘Sysstat’工具包中20个实用的Linux性能监控工具（包括mpstat, pidstat, iostat 和sar）
|
||||
===============================================================
|
||||
在我们上一篇文章中，我们已经学习了如何去安装和更新**sysstat**，并且了解了包中的一些实用工具。

20 Sysstat Commands for Linux Monitoring
|
||||
Linux系统监控的20个Sysstat命令
|
||||
今天，我们将会通过一些有趣的实例来学习**mpstat**, **pidstat**, **iostat**和**sar**等工具，这些工具可以帮组我们找出系统中的问题。这些工具都包含了不同的选项，这意味着你可以根据不同的工作使用不同的选项，或者根据你的需求来自定义脚本。我们都知道，系统管理员都会有点懒，他们经常去寻找一些更简单的方法来完成他们的工作。
|
||||
|
||||
Today, we are going to work with some interesting practical examples of **mpstat, pidstat, iostat** and **sar** utilities, which can help us to identify the issues. We have different options to use these utilities, I mean you can fire the commands manually with different options for different kind of work or you can create your customized scripts according to your requirements. You know Sysadmins are always bit Lazy, and always tried to find out the easy way to do the things with minimum efforts.

### sar – System Activity Reporter ###
|

###sar - 系统活动报告###
|
||||
|
||||
Using “**sar**” command, we can get the reports about whole system’s performance. This can help us to locate the system bottleneck and provide the help to find out the solutions to these annoying performance issues.
|
||||
我们可以使用‘**sar**’命令来获得整个系统性能的报告。这有助于我们定位系统性能的瓶颈，并且有助于我们找出这些烦人的性能问题的解决方法。
|
||||
|
||||
The Linux Kernel maintains some counter internally, which keeps track of all requests, their completion time and I/O block counts etc. From all these information, sar calculates rates and ratio of these request to find out about bottleneck areas.
|
||||
Linux内核维护者一些内部计数器，这些计数器包含了所有的请求及其完成时间和I/O块数等信息，sar命令从所有的这些信息中计算出请求的利用率和比例，以便找出瓶颈所在。
|
||||
|
||||
The main thing about the sar is that, it reports all activities over a period if time. So, make sure that sar collect data on appropriate time (not on Lunch time or on weekend.:)
|
||||
sar命令主要的用途是生成某段时间内所有活动的报告，因此，必需确保sar命令在适当的时间进行数据采集（而不是在午餐时间或者周末。）
|
||||
|
||||
13.Following is a basic command to invoke sar. It will create one file named “**sarfile**” in your current directory. The options ‘**-u**‘ is for CPU details and will collect **5** reports at an interval of **2** seconds.
|
||||
13.下面是执行sar命令的基本用法。它将会在当前目录下创建一个名为‘**sarfile**’的文件。‘**-u**’参数表示CPU详细信息，**5**表示生产5次报告，**2**表示每次报告的时间间隔为2秒。

14.In the above example, we have invoked sar interactively. We also have an option to invoke it non-interactively via cron using scripts **/usr/local/lib/sa1** and **/usr/local/lib/sa2** (If you have used **/usr/local** as prefix during installation time).
|
||||
14.在上面的例子中，我们交互的执行sar命令。sar命令提供了使用cron进行非交互的执行sar命令的方法，使用**/usr/local/lib/sa1**和**/usr/local/lib/sa2**脚本（如果你在安装时使用了**/usr/local**作为前缀）
|
||||
|

- **/usr/local/lib/sa1** is a shell script that we can use for scheduling cron which will create daily binary log file.

- **/usr/local/lib/sa2** is a shell script will change binary log file to human-readable form.
|

- **/usr/local/lib/sa1**是一个可以使用cron进行调度生成二进制日志文件的shell脚本。
|
||||
- **/usr/local/lib/sa2**是一个可以将二进制日志文件转换为用户可读的编码方式。
|
||||
|
||||
Use the following Cron entries for making this non-interactive:
|

使用如下Cron项目来将sar命令非交互化。
