centos 安装ganglia监控工具

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。

二、下载及安装

三、调试

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

发现报错



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



[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





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
