架構師成長之路1.1-系統監控工具htop
htop 是Linux系統中的一個互動的進程查看器，一個文本模式的應用程序(在控制檯或者X終端中)，須要ncurses。linux
與Linux傳統的top相比，htop更加人性化。它可以讓用戶交互式操做，支持顏色主題，可橫向或縱向滾動瀏覽進程列表，並支持鼠標操做。shell
與top相比，htop有如下優勢：網絡
- 能夠橫向或縱向滾動瀏覽進程列表，以便看到全部的進程和完整的命令行。
- 在啓動上，比top 更快。
- 殺進程時不須要輸入進程號。
- htop 支持鼠標操做。
- 支持進程樹狀顯示、按名稱查找進程
（顯示進程打開的文件<打開htop後選擇某一個進程，按s鍵便可用strace追蹤進程的系統調用>，及顯示進程內存映射狀況。）
1. htop獲取與安裝
Htop的安裝，既能夠經過源碼包編譯安裝，也能夠配置好yum源後網絡下載安裝。架構
本文介紹源碼安裝
- 步驟一、在htop的項目官方網站上：http://sourceforge.net/projects/htop/直接下載便可
已經將文件下載在linux系統上面，而後解包。編輯器
- 步驟二、要解包一個軟件的tarball，使用標準的tar命令。
- 步驟三、cd進入目錄後，檢查系統擁有合適的編譯器可以編譯源代碼，make構建各類二進制文件

安裝完成。
2.htop參數
鍵入htop 命令，打開htop。
左邊部分從上至下，分別爲，cpu、內存、交換分區的使用狀況，右邊部分爲：Tasks爲進程總數，當前運行的進程數、Load average爲系統1分鐘，5分鐘，10分鐘的平均負載狀況、Uptime爲系統運行的時間。
，就是進程實時情況。
-
PID：進行的標識號
-
USER：運行此進程的用戶
-
PRI：進程的優先級
-
NI：進程的優先級別值，默認的爲0，能夠進行調整
-
VIRT：進程佔用的虛擬內存值
-
RES：進程佔用的物理內存值
-
SHR：進程佔用的共享內存值
-
S：進程的運行情況，R表示正在運行、S表示休眠，等待喚醒、Z表示僵死狀態
-
%CPU：該進程佔用的CPU使用率
-
%MEM：該進程佔用的物理內存和總內存的百分比
-
TIME+：該進程啓動後佔用的總的CPU時間
-
COMMAND：進程啓動的啓動命令名稱
下面是 F1~F10 的功能和對應的字母快捷鍵。
| Shortcut Key | Function Key | Description | 中文說明 |
| h, ? | F1 | Invoke htop Help | 查看htop使用說明 |
| S | F2 | Htop Setup Menu | htop 設定 |
| / | F3 | Search for a Process | 搜索進程 |
| \ | F4 | Incremental process filtering | 增量進程過濾器 |
| t | F5 | Tree View | 顯示樹形結構 |
| <, > | F6 | Sort by a column | 選擇排序方式 |
| [ | F7 | Nice - (change priority) | 可減小nice值，這樣就能夠提升對應進程的優先級 |
| ] | F8 | Nice + (change priority) | 可增長nice值，這樣就能夠下降對應進程的優先級 |
| k | F9 | Kill a Process | 可對進程傳遞信號 |
| q | F10 | Quit htop | 結束htop |
如下命令行選項（COMMAND-LINE OPTIONS）
- -C --no-color 使用一個單色的配色方案
- -d --delay=DELAY 設置延遲更新時間，單位秒
- -h --help 顯示htop 命令幫助信息
- -u --user=USERNAME 只顯示一個給定的用戶的過程
- -p --pid=PID,PID… 只顯示給定的PIDs
- -s --sort-key COLUMN 依此列來排序
- -v –version 顯示版本信息
如下交互式命令（INTERACTIVE COMMANDS）
- 上下鍵或PgUP, PgDn 選定想要的進程，左右鍵或Home, End 移動字段，固然也能夠直接用鼠標選定進程；
- Space 標記/取消標記一個進程。命令能夠做用於多個進程，例如 "kill"，將應用於全部已標記的進程
- U 取消標記全部進程
- s 選擇某一進程，按s:用strace追蹤進程的系統調用
- l 顯示進程打開的文件: 若是安裝了lsof，按此鍵能夠顯示進程所打開的文件
- I 倒轉排序順序，若是排序是正序的，則反轉成倒序的，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 (在有多處理器的機器上) 設置 CPU affinity: 標記一個進程容許使用哪些CPU
- u 顯示特定用戶進程
- M 按Memory 使用排序
- P 按CPU 使用排序
- T 按Time+ 使用排序
- F 跟蹤進程: 若是排序順序引發選定的進程在列表上處處移動，讓選定條跟隨該進程。這對監視一個進程很是有用：經過這種方式，你可讓一個進程在屏幕上一直可見。使用方向鍵會中止該功能。
- K 顯示/隱藏內核線程
- H 顯示/隱藏用戶線程
- Ctrl-L 刷新
- Numbers PID 查找: 輸入PID，光標將移動到相應的進程上
3.htop使用
3.1. 顯示自帶幫助
鼠標點擊Help或者按F1 顯示自帶幫助
3.2. htop 設定
鼠標點擊Setup或者按下F2 以後進入htop 設定的頁面，Meters 頁面設定了頂端的一些信息顯示，頂端的顯示又分爲左右兩側，到底能顯示些什麼能夠在最右側那欄新增，要新增到上方左側（F5）或是右側（F6）均可以，這就是我的設定的範圍了。這裏多加了一個時鐘。
