在 CentOS 6.5 上安装 Ganglia 3.6.0 multi_interface插件

检查是否有modpython.so

ls -alh /usr/local/ganglia-3.6.0/lib64/ganglia/ | grep modpython

ganglia 默认是开启mod_python

./configure --help | grep python

--disable-python        exclude mod_python and support for metric modules written in python
--with-python=PATH      Specify prefix for python or full path to interpreter
  
如果安装发现没有modpython.so, 说明找不到Python.h, 需要安装python-devel,这个在configure.ac有做test
 
more ./configure.ac | grep Python

# check for Python executable
AC_MSG_CHECKING(Python version)
if test -f "$PyEXEC_INSTALLDIR/include/python/Python.h"; then
  if test -f "$PyEXEC_INSTALLDIR/include/python$PyVERSION/Python.h"; then
AC_MSG_CHECKING(Python support)		

下载gmond_python_modules

mkdir -p /usr/local/src
cd /usr/local/src
git clone https://github.com/ganglia/gmond_python_modules

创建目录

mkdir -p /etc/ganglia/conf.d
mkdir -p /usr/local/ganglia-3.6.0/lib64/ganglia/python_modules 

修改gmond.conf

vi /usr/local/ganglia-3.6.0/etc/conf.d/modpython.conf

检查是否有
modules {
  module {
	name = "python_module"
	path = "modpython.so"
	params = "/usr/local/ganglia-3.6.0/lib64/ganglia/python_modules"
  }
}

include ("/usr/local/ganglia-3.6.0/etc/conf.d/*.pyconf") 
修改成 
include ("/etc/ganglia/conf.d/*.pyconf")

复制文件

cd /usr/local/src/gmond_python_modules
cp network/multi_interface/conf.d/multi_interface.pyconf /etc/ganglia/conf.d/
cp network/multi_interface/python_modules/multi_interface.py /usr/local/ganglia-3.6.0/lib64/ganglia/python_modules/

修改multi_interface.pyconf

vi /etc/ganglia/conf.d/multi_interface.pyconf

param interfaces {
  value = "em1 br1"
}

重启gmond

service gmond restart
