1、nagios图形监控显示和报警管理nagios图形监控显示和报警管理服务端1、 yum安装pnp软件需要基础包图形依赖库yuminstallcairopangozlibzlib-develfreetypefreetype-develgdgd-devel-y2、 rrdtools依赖安装 软件都在oldboy_training_nagios_soft.zipcd /toolstarxflibart_lgpl-2.3.17.tar.gzcdlibart_lgpl-2.3.17./configuremakemakeinstall/bin/cp-r/usr/local/include/libart-2

8、perfdata 删除之前的内容删除两个命令定义：process-host-perfdata、process-service-perfdata添加如下 #process-host-perfdatacommanddefinitiondefinecommandcommand_nameprocess-host-perfdatacommand_line/usr/local/nagios/libexec/process_perfdata.pl#process-service-perfdatacommanddefinitiondefinecommandcommand_nameprocess-service

9、-perfdatacommand_line/usr/local/nagios/libexec/process_perfdata.pl 检查语法，重启服务/etc/init.d/nagios checkconfig/etc/init.d/nagios reload/etc/init.d/httpd start访问：http:/10.0.0.11/nagios/pnp/index.php 主机出图在vi hosts.cfg define host use linux-server host_name 204-zhuangjiajun alias 204-zhuangjiajun address 1

10、0.0.0.204 action_url /nagios/pnp/index.php?host=$HOSTNAME$ 也可以添加在模板vi templates.cfg搜索/linux-serverdefine host name linux-server ; The name of this host template check_period 24x7 ; By default, Linux hosts are checked round the clock check_interval 5 ; Actively check the host every 5 minutes retry_in

20、ION - ITS NOT A REAL SERVICE, JUST A TEMPLATE! action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$ 实现效果：nagios报警邮件报警邮件转短信短信网关 =老男孩推荐如果有值班 页面显示，由人打电话微信绑定邮箱对于不紧急的选择邮件报警，重要紧急的报警选择邮件+短信老男孩思想：花一定的费用，把业务做到最好，如果报警报不出来，损失更大重要报警思想该报的报出来，不该报的一点不要报出来配置报警步骤1、 开发短信报警脚本（短信网关需要收费的）rootoldboy-Alibexe
