架构师成长之路1.1-系统监控工具htop

htop 是Linux系统中的一个互动的进程查看器，一个文本模式的应用程序(在控制台或者X终端中)，需要ncurses。

与Linux传统的top相比，htop更加人性化。它可让用户交互式操作，支持颜色主题，可横向或纵向滚动浏览进程列表，并支持鼠标操作。

与top相比，htop有以下优点：

可以横向或纵向滚动浏览进程列表，以便看到所有的进程和完整的命令行。
在启动上，比top 更快。
杀进程时不需要输入进程号。
htop 支持鼠标操作。
支持进程树状显示、按名称查找进程
（显示进程打开的文件<打开htop后选择某一个进程，按s键即可用strace追踪进程的系统调用>，及显示进程内存映射情况。）

1. htop获取与安装

Htop的安装，既可以通过源码包编译安装，也可以配置好yum源后网络下载安装。

本文介绍源码安装

步骤1、在htop的项目官方网站上：http://sourceforge.net/projects/htop/直接下载即可

已经将文件下载在linux系统上面，然后解包。

步骤2、要解包一个软件的tarball，使用标准的tar命令。
步骤3、cd进入目录后，检查系统拥有合适的编译器能够编译源代码，make构建各种二进制文件

安装完成。

2.htop参数

键入htop 命令，打开htop。

左边部分从上至下，分别为，cpu、内存、交换分区的使用情况，右边部分为：Tasks为进程总数，当前运行的进程数、Load average为系统1分钟，5分钟，10分钟的平均负载情况、Uptime为系统运行的时间。

，就是进程实时状况。

PID：进行的标识号
USER：运行此进程的用户
PRI：进程的优先级
NI：进程的优先级别值，默认的为0，可以进行调整
VIRT：进程占用的虚拟内存值
RES：进程占用的物理内存值
SHR：进程占用的共享内存值
S：进程的运行状况，R表示正在运行、S表示休眠，等待唤醒、Z表示僵死状态
%CPU：该进程占用的CPU使用率
%MEM：该进程占用的物理内存和总内存的百分比
TIME+：该进程启动后占用的总的CPU时间
COMMAND：进程启动的启动命令名称

下面是 F1~F10 的功能和对应的字母快捷键。

Shortcut Key	Function Key	Description	中文说明
h, ?	F1	Invoke htop Help	查看htop使用说明
S	F2	Htop Setup Menu	htop 设定
/	F3	Search for a Process	搜索进程
\	F4	Incremental process filtering	增量进程过滤器
t	F5	Tree View	显示树形结构
<, >	F6	Sort by a column	选择排序方式
[	F7	Nice - (change priority)	可减少nice值，这样就可以提高对应进程的优先级
]	F8	Nice + (change priority)	可增加nice值，这样就可以降低对应进程的优先级
k	F9	Kill a Process	可对进程传递信号
q	F10	Quit htop	结束htop

以下命令行选项（COMMAND-LINE OPTIONS）

-C --no-color　　　　　　使用一个单色的配色方案
-d --delay=DELAY　　　　设置延迟更新时间，单位秒
-h --help　　　　　　　　显示htop 命令帮助信息
-u --user=USERNAME　　只显示一个给定的用户的过程
-p --pid=PID,PID…　　　只显示给定的PIDs
-s --sort-key COLUMN　依此列来排序
-v –version　　　　　　　显示版本信息

以下交互式命令（INTERACTIVE COMMANDS）

上下键或PgUP, PgDn 选定想要的进程，左右键或Home, End 移动字段，当然也可以直接用鼠标选定进程；
Space 标记/取消标记一个进程。命令可以作用于多个进程，例如 "kill"，将应用于所有已标记的进程
U 取消标记所有进程
s 选择某一进程，按s:用strace追踪进程的系统调用
l 显示进程打开的文件: 如果安装了lsof，按此键可以显示进程所打开的文件
I 倒转排序顺序，如果排序是正序的，则反转成倒序的，反之亦然
+, - When in tree view mode, expand or collapse subtree. When a subtree is collapsed a "+" sign shows to the left of the process name.
a (在有多处理器的机器上) 设置 CPU affinity: 标记一个进程允许使用哪些CPU
u 显示特定用户进程
M 按Memory 使用排序
P 按CPU 使用排序
T 按Time+ 使用排序
F 跟踪进程: 如果排序顺序引起选定的进程在列表上到处移动，让选定条跟随该进程。这对监视一个进程非常有用：通过这种方式，你可以让一个进程在屏幕上一直可见。使用方向键会停止该功能。
K 显示/隐藏内核线程
H 显示/隐藏用户线程
Ctrl-L 刷新
Numbers PID 查找: 输入PID，光标将移动到相应的进程上

3.htop使用

3.1. 显示自带帮助

鼠标点击Help或者按F1 显示自带帮助

3.2. htop 设定

鼠标点击Setup或者按下F2 之后进入htop 设定的页面，Meters 页面设定了顶端的一些信息显示，顶端的显示又分为左右两侧，到底能显示些什么可以在最右侧那栏新增，要新增到上方左侧（F5）或是右侧（F6）都可以，这就是个人设定的范围了。这里多加了一个时钟。
