Nagios監控window主機和LInux主機網卡流量
安裝snmp
yum install net-snmp 修改如下 [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
首先將check_triffic.sh腳本拷貝到/usr/local/nagios/libexec/里面。然后在/usr/local/nagios/etc/objects/commands.cfg 文件中添加
define command{
command_name check_traffic
command_line $USER1$/check_traffic.sh -V 2c -C mypublic -H $HOSTADDRESS$ -I $ARG1$ -w $ARG2$,$ARG3$ -c $ARG4$,$ARG5$
} 檢測自己網卡型號
[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號網卡 Interface index 2 orresponding to eth0 #2號網卡
輸出信息中index后面的數字就是你要監控網卡的代號
可以自己通過命令先執行一下：
/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 代表snmp版本 C 代表community的名稱 H 代表主機IP I 代表網卡號 w 警告 c 緊急 補充：10,10 30,30（代表in，out）
輸出：
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
如果你跟我一樣報錯
[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
請修改
解決： vim /etc/snmp/snmpd.conf 修改兩處： 一處： access notConfigGroup "" any noauth exact all none none 或者 access notConfigGroup "" any noauth exact mib2 none none 二處： view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
添加服務
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
} 我這是通過NRPE監控遠程LInux主機所以這個check_traffic腳本先放到遠程linux主機/usr/local/nagios/libexec下，然后修改/usr/local/nagios/etc/nrpe.cf
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
監控頁面顯示服務未知？
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.
修改其權限為nagios.nagios即可

即可恢復看到網卡流量

監控本機網卡流量
先定義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 $ARG4$,$ARG5$
} 定義服務
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
} 單位默認是Kbps
監控window主機
首先安裝snmp 安裝方式 開始—>控制面板---找到簡單網絡管理協議SNMP 打勾--確定-開始安裝 應該需要重啟。
然后開始運行services.msc 找到snmp server 服務 右鍵屬性 安全 社區添加一個名字 用來驗證 我的是mypubic 接受來自那些主機 填你的nagios server 即可
查看服務器網卡序列
[root@www ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C mypublic -H 192.168.0.137 -L #找到你要監控的網卡 我這里自己是window 7 用的無線 #前提window 主機要安裝NSClient++ 才可以被監控 List Interface for host 192.168.0.137.

檢測能不能從window主機獲取流量信息。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
定義window.cf 添加主機和服務
define service{
use generic-service,srv-pnp
host_name winserver
service_description Network
check_command check_traffic!12!100!100!300!300
} 檢測看有沒有語法錯誤。
