天兔(Lepus)监控操作系统(OS)安装配置

天兔(Lepus)监控操作系统(OS)安装配置

监控和被监控端都要安装和配置snmp:

[root@yoon]# yum install net-snmp*

[root@yoon]# vi /etc/snmp/snmpd.conf

41行将default均改为监控服务器ip;团体名被监控机和监控机一致,示例如下:

com2secnotConfigUser 192.168.11.100  yoon123456


62行将systemview改为all,供所有snmp访问权限

access notConfigGroup "" any noauth exact all none none

85行将#注释符号去掉

viewall included .1 80

 

修改snmp级别以减少日志输出
[root@HE1 home]# vi /etc/init.d/snmpd

#OPTIONS="-LS0-6d-Lf /dev/null -p /var/run/snmpd.pid"
OPTIONS="-LS 4 d -p /var/run/snmpd.pid -a"


[root@yoon]# /etc/init.d/snmpd restart

Stoppingsnmpd: [ OK ]

Startingsnmpd: [ OK ]


验证snmp服务

[root@HE1 bin]# ps-ef | grep 'snmpd'

root 26100 1 0 11:20 ? 00:00:00 /usr/sbin/snmpd -LS 4 d -p/var/run/snmpd.pid -a

root 26114 25540 0 11:30 pts/0 00:00:00 grep snmpd

 

监控机修改lepus配置文件添加44,45,46行内容

[root@HE3lepus]# vi /usr/local/lepus/check_os.sh

在43行后添加44,45,46行内容

mem_buffered=`/usr/bin/snmpwalk -v1 -c ${community} ${ip} UCD-SNMP-MIB::memBuffer.0 |cut -d= -f2 |awk -F ' ' '{print $2}'`

mem_cached=`/usr/bin/snmpwalk -v1 -c ${community} ${ip} UCD-SNMP-MIB::memCached.0 |cut -d= -f2 |awk -F ' ' '{print $2}'`

mem_usage_rate=`/usr/bin/snmpdf -v1 -c ${community} ${ip} |grep "Physical"|awk '{print $6}'`

mem_available=$[$mem_free+$mem_buffered+$mem_cached]

if [ -z $mem_shared ]; then

mem_shared=0

fi

[root@HE3 lepus]#python check_os.py
