nagios监控window主机和LInux主机网卡流量
安装snmplinux
yum install net-snmp 修改以下 [root@xen etc]# grep -v '#' /etc/snmp/snmpd.conf |grep -v '^$' com2sec notConfigUser default mypublic com2sec notConfigUser 192.168.0.138 mypublic group notConfigGroup v1 notConfigUser group notConfigGroup v2c notConfigUser view systemview included .1.3.6.1.2.1.1 view systemview included .1.3.6.1.2.1.25.1.1 access notConfigGroup "" any noauth exact all none none view all included .1 80 view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc syslocation Unknown (edit /etc/snmp/snmpd.conf) syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf) dontLogTCPWrappersConnects yes
首先将check_triffic.sh脚本拷贝到/usr/local/nagios/libexec/里面。而后在/usr/local/nagios/etc/objects/commands.cfg 文件中添加ios
define command{
command_name check_traffic
command_line $USER1$/check_traffic.sh -V 2c -C mypublic -H $HOSTADDRESS$ -I $ARG1$ -w $ARG2$,$ARG3$ -c $ARG4$,$ARG5$
}
检测本身网卡型号shell
[root@xen etc]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.156 -L List Interface for host 192.168.0.156. Interface index 1 orresponding to lo #1号网卡 Interface index 2 orresponding to eth0 #2号网卡
/usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.156 -I 2 -w 10,10 -c 30,30
V 表明snmp版本 C 表明community的名称 H 表明主机IP I 表明网卡号 w 警告 c 紧急 补充：10,10 30,30（表明in，out）
OK - The Traffic In is 0.11KB, Out is 0.0KB, Total is 0.11KB. The Check Interval is 109s |In=0.11KB;1200;1700;0;0 Out=0.0KB;1500;1800;0;0 Total=0.11KB;2700;3500;0;0 Interval=109s;1200;1800;0;0
若是你跟我同样报错网络
[root@xen libexec]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.156 -L List Interface for host 192.168.0.156. Interface index = No Such Object available on this agent at this OID
请修改app
解决： vim /etc/snmp/snmpd.conf 修改两处： 一处： access notConfigGroup "" any noauth exact all none none 或者 access notConfigGroup "" any noauth exact mib2 none none 二处： view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
添加服务oop
vim /usr/local/nagios/etc/objects/linuxhost.cfg
define service{
use generic-service,srv-pnp ; Name of service template to use
host_name linuxhost
service_description check_traffic
check_command check_nrpe!check_traffic
}
我这是经过NRPE监控远程LInux主机因此这个check_traffic脚本先放到远程linux主机/usr/local/nagios/libexec下，而后修改/usr/local/nagios/etc/nrpe.cfui
添加
command[check_traffic]=/usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 127.0.0.1 -I 2 -w 1200,1500 -c 1700,1800 -K -B
监控页面显示服务未知？
Unknown - Read or Write File /var/tmp/check_traffic_192.168.0.156_2__itnms.hist_dat_64 Error with user uid=542(nagios) gid=543(nagios) groups=543(nagios),544(nagcmd) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023.
修改其权限为nagios.nagios便可

便可恢复看到网卡流量

监控本机网卡流量
先定义command.cf
define command{
command_name check_traffic
command_line $USER1$/check_traffic.sh -V 2c -C mypublic -H $HOSTADDRESS$ -I $ARG1$ -w $ARG2$,$ARG3$ -c $ARG4$,$ARG5$
}
定义服务
define service{
use local-service,srv-pnp ; Name of service template to use
host_name localhost
service_description check_traffic
check_command check_traffic!3!100!100!300!300
}
单位默认是Kbps
监控window主机
首先安装snmp 安装方式 开始—>控制面板---找到简单网络管理协议SNMP 打勾--肯定-开始安装 应该须要重启。
而后开始运行services.msc 找到snmp server 服务 右键属性 安全 社区添加一个名字 用来验证 个人是mypubic 接受来自那些主机 填你的nagios server 便可
查看服务器网卡序列
[root@www ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.137 -L #找到你要监控的网卡 我这里本身是window 7 用的无线 #前提window 主机要安装NSClient++ 才能够被监控 List Interface for host 192.168.0.137.

检测能不能从window主机获取流量信息。第一次可能很慢
[root@www ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.137 -I 12 -w 10,10 -c 30,30 Error in packet Reason: (noSuchName) There is no such variable name in this MIB. Failed object: IF-MIB::ifHCOutOctets.12 Critical - The Traffic In is 11Kbps, Out is 52Kbps, Total is 63Kbps. The Check Interval is 494s |In=11Kbps;10;30;0;0 Out=52Kbps;10;30;0;0 Total=63Kbps;20;60;0;0 Interval=494s;1200;1800;0;0
定义window.cf 添加主机和服务
define service{
use generic-service,srv-pnp
host_name winserver
service_description Network
check_command check_traffic!12!100!100!300!300
}
检测看有没有语法错误。
重启nagios 看监控页面
