nagios 流量监控文档
1、安装snmpd服务
yum -y install net-snmp*
2、安装bc软件包
yum install bc
3、修改snmpd.conf
vi /etc/snmp/snmpd.conf
用下面一段替换原来的
========================================
# sec.name source community
com2sec local localhost nagios
####
# Second, map the security names into group names:
# sec.model sec.name
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
group MyRWGroup usm initial
group MyROGroup v1 mynetwork
group MyROGroup v2c mynetwork
group MyROGroup usm mynetwork
####
# Third, create a view for us to let the groups have rights to:
# incl/excl subtree mask
view all included .1 80
####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:
# context sec.model sec.level match read write notif
access MyRWGroup "" any noauth exact all none none
=======================================
4、上传流量监控脚本
上传check_traffic.sh至/usr/local/nagios/libexec
chown nagios.nagios check_traffic.sh
chmod 777 check_traffic.sh
5、测试是否正常采集
/usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H 127.0.0.1 -L
显示如下为正确
========================
List Interface for host 127.0.0.1.
Interface index 1 orresponding to lo
Interface index 2 orresponding to bond0
Interface index 3 orresponding to eth0
Interface index 4 orresponding to eth1
Interface index 5 orresponding to sit0
========================
/usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H 127.0.0.1 -I 2 -w 300,350 -c 500,600 -K –B
显示如下为正确
========================
OK - The Traffic In is 356Kbps, Out is 414Kbps, Total is 770Kbps.
The Check Interval is 30s |In=356Kbps;1200;1700;0;0 Out=414Kbps;1500;1800;0;0 Total=770Kbps;2700;3500;0;0 Interval=30s;1200;1800;0;0
========================
6、更改采集数据的权限
chmod 777 /var/tmp/check_traffic*
7、更改nrpe.cfg增加如下行
command[check_traffic]=/usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H 127.0.0.1 -I 2 -w 300,350 -c 500,600 -K –B
重启nrpe程序
ps aux |grep nrpe
nagios 2822 0.0 0.0 4808 1448 ? Ss Jun01 0:04 /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
root 1123 0.0 0.0 5936 736 pts/2 S+ 11:02 0:00 grep nrpe
kill -9 2822
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
8、监控端修改
vi /usr/local/nagios/etc/services.cfg
#监控网络流量
define service{
#host_name WEB
hostgroup_name sa-servers
service_description check_traffic
check_command check_nrpe!check_traffic
max_check_attempts 4
normal_check_interval 1
retry_check_interval 2
check_period 24x7
notification_interval 10
notification_period 24x7
notification_options w,u,c,r
contact_groups sagroup
}
重启nagios
service nagios restart
