解决ganglia客户端加载模块失败的小错误

环境debain 6.0
安装客户端ganglia
root@mdb:/etc/ganglia# apt-cache search ganglia
collectd-core - statistics collection and monitoring daemon (core system)
ganglia-monitor - cluster monitoring toolkit - node daemon
ganglia-webfrontend - cluster monitoring toolkit - web front-end
gmetad - cluster monitoring toolkit - Ganglia Meta-Daemon
libganglia1-dev - cluster monitoring toolkit - development libraries
libganglia1 - cluster monitoring toolkit - shared libraries

作为客户端，只需要
root@mdb:/etc/ganglia# apt-get install ganglia-monitor
安装完成
查看gmond加载模块
root@mdb:/usr/lib64/ganglia# gmond -m

root@mdb:/etc/ganglia# ls /usr/lib64/ganglia/
modcpu.so  moddisk.so  modload.so  modmem.so  modmulticpu.so  modnet.so  modproc.so  modpython.so  modsys.so

解决办法很简单
只需要将默认的加载模块路径更改为绝对路径即可
vi /etc/ganglia/gmond.conf
