一、ganglia基本介绍

ganglia是分布式的监控系统,有两个Daemon,分别是:客户端GangliaMonitoring Daemon (gmond)和服务端GangliaMeta Daemon (gmetad),还有GangliaPHP Web 

Frontend(基于web的动态访问方式)组成是一个Linux下图形化监控系统运行性能的软件,界面美观、丰富,功能强大而ganglia又依赖于一个web服务器用来显示集群状态，用rrdtool来存储数据和生成曲线图，需要xml解析因此需要expat，配置文件解析需要libconfuse。

Ganglia是一个监控服务器，集群的开源软件，能够用曲线图表现最近一个小时，最近一天，最近一周，最近一月，最近一年的服务器或者集群的cpu负载,内存,网络,硬盘等指标。

Ganglia的强大在于：ganglia服务端能够通过一台客户端收集到同一个网段的所有客户端的数据，ganglia集群服务端能够通过一台服务端收集到它下属的所有客户端数据。这个体系设计表示一台服务器能够通过不同的分层能够管理上万台机器。这个功能是其他mrtg,nagios,cacti所不能比拟。

三、调试

访问页面http://192.168.0.104/ganglia/index.php

发现报错

是因为相应的目录没有建，而且权限不对

建立相应的目录，将目录权限改为777

mkdir -p /var/www/html/ganglia/dwoo/compiled
mkdir -p /var/www/html/ganglia/dwoo/cache
chmod 777 /var/www/html/ganglia/dwoo/compiled
chmod 777 /var/www/html/ganglia/dwoo/cache

[root@ws ganglia-web]# find . -type d 
.
./cache
./conf
./dwoo
./dwoo/cache
./dwoo/compiled
./dwoo/compiled/templates
./dwoo/compiled/templates/default
[root@ws ganglia-web]# pwd

/var/lib/ganglia-web

然后重启httpd，重新访问

这是ganglia本机的一些监控信息

下面还需要对被监控主机进行配置。

[root@localhost yum.repos.d]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@localhost yum.repos.d]# yum install  ganglia-gmond 

[root@ws softs]# rpmbuild -tb ganglia-3.6.0.tar.gz 
error: Failed build dependencies:
        libpng-devel is needed by ganglia-3.6.0-1.i386
        python-devel is needed by ganglia-3.6.0-1.i386

解决方法

[root@ws ~]# yum install libpng-devel python-devel  -y
