1 nagios 守护进程引起的一系列问题
1 影响nagios web页面收集监控信息
致使页面出现时而收集不到服务信息
2 影响pnp查看图形化，出图缓慢
3
影响查看服务状态信息，致使有时候查看不了服务状态
解决方法
通过命令ps -ef|grep nagios.cfg确认
是否开启多个守护进程
如果发现多个全部kill掉在重新启动守护进程
kill -9 xxxx
原因：启动了两个nagios进程，可通过命令ps -ef|grep
nagios.cfg确认。全kill掉之后再启动就可以了。也可以在nagios启动脚本（/etc/init.d/nagios）中加入判
断，start时如果已有nagios进程在运行则强制kill，kill成功再继续启动，失败则退出。
