nagios监控配置错误汇总

1.check_iftraffic监控网卡流量的配置及错误解决办法

服务端：

添加以下内容：

vim /usr/local/nagios/etc/objects/commands.cfg

#check iftraffic
define command{
        command_name    check_iftraffic
        command_line    $USER1$/check_iftraffic -H $HOSTADDRESS$ -i $ARG1$ -w $ARG2$ -c $ARG3$ -b $ARG4$ -u $ARG5$
}

vim /usr/local/nagios/etc/objects/62xxx.cfg

define service{
        use                             local-service
        host_name                       62xxx
        service_description             网卡流量
        check_command                   check_nrpe!check_iftraffic!"eth0"!50!100!100!m
        notifications_enabled           0
}

监控客户端：

vim /usr/local/nagios/etc/nrpe.cfg

command[check_iftraffic]=/usr/local/nagios/libexec/check_iftraffic_nrpe.pl -i eth0 -w 50 -c 100 -b 100 -u m

重启服务后，nagios监控页面提示UNKNOWN,NRPE: Unable to read output
解决办法：在监控客户端执行  /usr/local/nagios/libexec/check_iftraffic_nrpe.pl -i eth0 -w 50 -c 100 -b 100 -u m 

然后会在 /tmp 下面 生成一个文件 ls /tmp/ traffic_ifeth0 修改traffic_ifeth0的所属权限 chown nagios.nagios /tmp/traffic_ifeth0 -R

这样问题就OK了！

2.nagios错误日志里面 tailf /var/log/message提示

。。。。。。等等吧

这个错误是因为nagios多进程引起的，你可以ps -ef | grep nagios 发现有多个进程，把他们全部杀掉，然后重启 /etc/init.d/nagios start ，问题就OK了！

nagios启用通知提示错误：“ 无法打开要更新的命令文件，外部命令文件或目录权限不对，参考FAQ设置正确的权限”
