Collcted Plugin Development and Compiling (AREAWELL AW-2111A Plugin)

下載 collectd 原始碼

$ wget https://github.com/collectd/collectd/archive/collectd-5.4.1.tar.gz
$ tar zxf collectd-5.4.1.tar.gz

下載 Collectd AREAWELL AW-2111A plugin

$ git clone https://github.com/a0726h77/cloudPower-collectd-plugin.git

將 AW-2111A plugin 複製到 Collectd 原始碼資料夾

$ cp -r cloudPower-collectd-plugin/* collectd-collectd-5.4.1/src/

修改編譯設定，加入 plugin

$ cd collectd-collectd-5.4.1/
$ vi configure.ac

....
AC_PLUGIN([cloudpower], [yes], [cloudpower statistics])
....

$ vi src/Makefile.am

....
if BUILD_PLUGIN_CLOUDPOWER
pkglib_LTLIBRARIES += cloudpower.la
cloudpower_la_SOURCES = cloudpower.c
cloudpower_la_LDFLAGS = -module -avoid-version
cloudpower_la_LIBADD = -L. -lcloudPowerManagerTool
collectd_LDADD += "-dlopen" cloudpower.la
collectd_DEPENDENCIES += cloudpower.la
endif
....

$ vi src/types.db

....
electric        value:GAUGE:U:U
....

* Makefile.am 裏需指定模組對 libcloudPowerManagerTool.a 使用靜態連結

安裝相依套件

# apt-get install build-essential automake bison flex autoconf pkg-config libtool libgcrypt20-dev libltdl-dev libglib2.0-dev lib32z1-dev gcc-4.9-multilib

編譯 & 安裝

$ ./build.sh
$ ./configure CFLAGS="-m32" --prefix=/opt/collectd

CFLAGS="-m32"  編譯 collectd 成 32 位元執行檔，因爲官方給的

libcloudPowerManagerTool.a 只有 32 位元版本

--prefix  指定安裝路徑

$ make
# make all install

載入模組

# vi /opt/etc/collectd.conf

....
LoadPlugin cloudpower
....
<Plugin cloudpower>
        <Node "1F">
                Host "192.168.x.x"
        </Node>
</Plugin>
....

執行

# /opt/collectd-5.4.1/sbin/collectd -C /opt/collectd-5.4.1/etc/collectd.conf -f

Compile Collectd plugin with static link library

* 可參考 iptables plugin 的設定

$ cp libfact.a src/
$ vi src/Makefile.am

if BUILD_PLUGIN_MYPLUGIN
....
myplugin_la_LIBADD = -L. -lfact
....
endif

$ make
