RRDTool的安装及使用向导

下载
进入

http://oss.oetiker.ch/rrdtool/pub/
下载最新的RRDTool

再进入
http://oss.oetiker.ch/rrdtool/pub/libs/
下载所需要库:
[   ]freetype-2.1.10.tar.bz2   04-May-2006 15:18  1.0M  
[CMP]libpng-1.2.10.tar.gz      04-May-2006 15:18  813K  
[CMP]libart_lgpl-2.3.17.tar.gz 04-May-2006 15:18  386K  
[CMP]zlib-1.2.3.tar.gz         18-Jul-2005 15:38  485K  


设置目录

设置安装目录及编译目录:
BUILD_DIR=/tmp/rrdbuild
INSTALL_DIR=/usr/local/rrdtool-1.2.15
mkdir -p $BUILD_DIR
cd $BUILD_DIR

把下载的所有库放入这个目录


编译Zlib

tar  zxf zlib-1.2.3.tar.gz
cd zlib-1.2.3
env CFLAGS="-O3 -fPIC" ./configure --prefix=$BUILD_DIR/lb
make
make install


编译LibPng

tar zxvf libpng-1.2.10.tar.gz
cd libpng-1.2.10
env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
    ./configure --disable-shared --prefix=$BUILD_DIR/lb
make
make install


编译FreeType

tar jxvf freetype-2.1.10.tar.bz2
cd freetype-2.1.10
env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
    ./configure --disable-shared --prefix=$BUILD_DIR/lb
make
make install

注意:此处解压是带"j"参数,因为是bz2包;其它是带"z"参数


编译libart_lgpl

tar zxvf libart_lgpl-2.3.17.tar.gz
cd libart_lgpl-2.3.17
env CFLAGS="-O3 -fPIC" ./configure --disable-shared --prefix=$BUILD_DIR/lb
make
make install


编译RRDTool

IR=-I$BUILD_DIR/lb/include
CPPFLAGS="$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng"
LDFLAGS="-L$BUILD_DIR/lb/lib"
CFLAGS=-O3
export CPPFLAGS LDFLAGS CFLAGS

./configure --prefix=$INSTALL_DIR --disable-python --disable-tcl
make clean
make
make install

最后,可以将BIN目录加入PATH:
export PATH=/usr/local/rrdtool-1.2.15/bin:$PATH



使用要点
建库
  rrdtool create test.rrd             \
           --start 920804400          \
           DS:speed:COUNTER:600:U:U   \
           RRA:AVERAGE:0.5:1:24       \
           RRA:AVERAGE:0.5:6:10

DS是数据源,默认是5分钟采一次,6:10表示,每隔5分钟采一次,共采6次计算一次平均值(即半小时),并留10次这样的平均值(保留5小时数据)

加入数据
rrdtool update test.rrd 920808300:12420 
即以time:value对的方式向它添加

出图
rrdtool graph speed.png                                 \
        --start 920804400 --end 920808000               \
        DEF:myspeed=test.rrd:speed:AVERAGE              \
        LINE2:myspeed#FF0000

LINE2表示用2象素的线来画,FF0000是红色
DEF是定义一个变量

计算后出图
rrdtool graph speed3.png                             \
     --start 920804400 --end 920808000               \
     --vertical-label km/h                           \
     DEF:myspeed=test.rrd:speed:AVERAGE              \
     "CDEF:kmh=myspeed,3600,*"                       \
     CDEF:fast=kmh,100,GT,kmh,0,IF                   \
     CDEF:good=kmh,100,GT,0,kmh,IF                   \
     HRULE:100#0000FF:"Maximum allowed"              \
     AREA:good#00FF00:"Good speed"                   \
     AREA:fast#FF0000:"Too fast"

CDEF是计算变量
kmh=myspeed,3600,*表示,kmh是myspeed*3600,引号是为防止*被误解
kmh,100,GT,kmh,IF表示,((( kmh,100 ) GT ), 0, kmh) IF,也即判断是kmh大于100取0值,否则取值kmh
HRULE是画一条警戒线

DS种类
COUNTER - 持续增长值,RRD会前后相减再除时间计算平均值
GAUGE - 测量值,RRD不做处理,直接存
DERIVE - 变化值可以为负,其它与COUNTER一致
ABSOLUTE - 也是不改变其值,直接存(与GAUGE有何区别呢?)

最大值的WRAP
当到达最大值时,COUNTER会被RESET,导致前后两值相减为负,这不符合COUNTER的定义,所以它会尝试使用32位的最大值与这个负值相加来得到正常的正值,如果还是负,它会尝试用64位的最大值来使它变正。大部分情况可以处理。

安装cacti-ddrtool时报错configure: error: Please fix the library issues listed above and try again  

最近,在安装ddrtool,进行编译时,提示如下:

#./configure --prefix=/usr/local/ddrtool

configure: error: Please fix the library issues listed above and try again.

解决方法如下:

安装pango

yum -y install pango*

安装libart_lgpl-devel这个包
yum -y install libart_lgpl-devel

这样,安装完成后就可以继续了

#make && make install

这样,ddrtool就安装完成了
