Ganglia客户端不会向64位CentOS上的服务器报告指标

Question

我在Ubuntu上有Ganglia服务器，在CentOS客户端上有Ganglia client (gmond)。客户端计算机的指标不会显示在UI上

当我尝试在客户端重新启动gmond服务时，我得到了错误：

service gmond restart
Shutting down GANGLIA gmond:                               [  OK  ]
Starting GANGLIA gmond: Cannot load /usr/lib/ganglia/modcpu.so metric module:     /usr/lib/ganglia/modcpu.so: cannot open shared object file: No such file or directory
Cannot load /usr/lib/ganglia/moddisk.so metric module: /usr/lib/ganglia/moddisk.so: cannot open shared object file: No such file or directory
Cannot load /usr/lib/ganglia/modload.so metric module: /usr/lib/ganglia/modload.so: cannot open shared object file: No such file or directory
Cannot load /usr/lib/ganglia/modmem.so metric module: /usr/lib/ganglia/modmem.so: cannot open shared object file: No such file or directory
Cannot load /usr/lib/ganglia/modnet.so metric module: /usr/lib/ganglia/modnet.so: cannot open shared object file: No such file or directory

Cannot load /usr/lib/ganglia/modsys.so metric module: /usr/lib/ganglia/modsys.so: cannot open shared object file: No such file or directory

此外，/var/log/messages还将报告：

/usr/sbin/gmond[6374]: Unable to find the metric information for 'pkts_in'. Possible that the module has not been loaded.#012

在64位机器上，错误消息中提到的.so文件的路径应该是/usr/lib64/ganglia/，因此它报告在/usr/lib/ganglia/modcpu.so找不到的文件实际上位于/usr/lib64/ganglia/modcpu.so。

与documented here一样，这些模块路径的配置也在/etc/ganglia/gmond.conf中。修改文件中的路径，并在客户端重新启动gmond服务，就可以了。
