nagios下用grafana绘图(二)

现在不需要安装elasticsearch了,所以省去了很多步骤.

使用如下工具:

graphitegrafana-3.1.1-1470047149.x86_64graphios

部署环境:

Centos 6.5python 2.6nagios 4.1.1

一.安装graphite

1.关闭selinux

2.安装依赖工具

yum install epel-release -yyum install bitmap bitmap-fonts-compat Django django-tagging fontconfig cairo python-devel python-memcached python-twisted  pycairo mod_python python-ldap python-simplejson memcached python-zope-interface mod_wsgi python-sqlite2  Django MySQL-python  -y

安装pytz

 pip install pytz

carbon依赖Twisted,如果是python2.6,新版的Twisted不支持python2.6,需手动安装支持2.6的版本,这里用Twisted-15

wget https://pypi.python.org/packages/76/9a/ed7a9cabefd919c861249d39d11111d5d8fba2e8d0b2a1bce7ee8933a8fd/Twisted-15.0.0.tar.bz2#md5=f52bfe112a3aa33dd1d323c7c1e99f16tar jxvf Twisted-15.0.0.tar.bz2cd Twisted-15.0.0python setup.py install

3.安装graphite
使用pip安装

pip install whisperpip install carbonpip install graphite-web

添加配置文件

cd /opt/graphite/conf/cp carbon.conf.example carbon.confcp storage-schemas.conf.example storage-schemas.confcp graphite.wsgi.example graphite.wsgi

4.配置apache

cat /opt/graphite/examples/example-graphite-vhost.conf  >> /etc/httpd/conf/httpd.confvim /etc/httpd/conf/httpd.conf添加 Listen 8081修改端口为8081<VirtualHost *:8081>修改WSGISocketPrefix 为 WSGISocketPrefix /var/run/httpd/wsgi初始化数据库cd /opt/graphite/webapp/graphite/cp local_settings.py.example local_settings.pypython manage.py syncdbchown -R apache:apache /opt/graphite

5.启动graphite

/opt/graphite/bin/carbon-cache.py startservice  httpd restart

访问http://ip:8081 即可进入graphite

二.安装配置graphios

1.安装

git clone https://github.com/shawn-sterling/graphios.gitcd graphiospython setup.py installmkdir -p /var/spool/nagios/graphioschown nagios:nagios -R /var/spool/nagios

2.配置
安装完成后,会自动在/usr/local/nagios/etc/nagios.cfg中添加graphios的配置
注释掉这行,避免配置冲突

cfg_dir=/usr/local/nagios/etc/objects

手动添加command的配置

vim /usr/local/nagios/etc/objects/commands.cfgdefine command {        command_name    graphite_perf_host        command_line    /bin/mv /var/spool/nagios/graphios/host-perfdata /var/spool/nagios/graphios/host-perfdata.$TIMET$        }define command {        command_name    graphite_perf_service        command_line    /bin/mv /var/spool/nagios/graphios/service-perfdata /var/spool/nagios/graphios/service-perfdata.$TIMET$        }在nagios对应的主机或服务中,添加 _graphiteprefix 值如define host {    host_name                   gzimg110    check_command               check_ping    _graphiteprefix                ping}

3.配置graphios

vim /etc/graphios/graphios.cfg
修改如下内容

debug = Falseenable_carbon = Truesleep_max = 3

vim /usr/bin/graphios.py
将对应值修改为如下内容

config_file = '/etc/graphios/graphios.cfg'debug = False

启动graphios

service graphios startservice nagios restart

可以查看日志,看是否正常
tail /usr/local/nagios/var/graphios.log

查看/opt/graphite/storage/whisper/下是否有对应的文件产生

三.安装配置grafana

1.安装
可以访问官网获取最新的版本
http://docs.grafana.org/
本次使用3.1.1

wget https://grafanarel.s3.amazonaws.com/builds/grafana-3.1.1-1470047149.x86_64.rpmrpm -ivh grafana-3.1.1-1470047149.x86_64.rpm

2.配置
grafana默认使用3000端口
vim /etc/grafana/grafana.ini
开启如下选项

protocol = httphttp_port = 3000admin_user = adminadmin_password = admin

3.使用
启动grafana

service  grafana-server start

打开浏览器,访问grafana
http://ip:3000

按如下步骤,添加graphite数据源

添加完成后,点开dashborads,即可添加对应的服务了.

最终效果:
