一个、ganglia基本介绍
ganglia它是一个分布式监控系统,那里有两个Daemon,每间:clientGangliaMonitoring Daemon (gmond)和服务端GangliaMeta Daemon (gmetad),还有GangliaPHP Web
Frontend(基于web的动态訪问方式)组成是一个Linux下图形化监控系统执行性能的软件,界面美观、丰富,功能强大而ganglia又依赖于一个webserver用来显示集群状态，用rrdtool来存储数据和生成曲线图，须要xml解析因此须要expat。配置文件解析须要libconfuse。
Ganglia是一个监控server，集群的开源软件，可以用曲线图表现近期一个小时，近期一天，近期一周，近期一月。近期一年的server或者集群的cpu负载,内存,网络,硬盘等指标。
Ganglia的强大在于：ganglia服务端可以通过一台client收集到同一个网段的全部client的数据。ganglia集群服务端可以通过一台服务端收集到它下属的全部client数据。这个体系设计表示一台server可以通过不同的分层可以管理上万台机器。
这个功能是其它mrtg,nagios,cacti所不能比拟。

三、调试
訪问页面http://192.168.0.104/ganglia/index.php
发现报错
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYXZpbGlmYW5z/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
是由于对应的文件夹没有建，并且权限不正确
建立对应的文件夹，将文件夹权限改为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
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYXZpbGlmYW5z/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
[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
然后重新启动httpd，又一次訪问
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYXZpbGlmYW5z/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
这是ganglia本机的一些监控信息
以下还须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
