使用snmp监控

1.snmp简介

snmp协议：linux ，windows ，交换机，路由器，打印机，ups
simple network manager protocol：

监控指标oid object id
.1.3.6.1.2.1.25.2.3.1.1 剩余内存
.1.3.6.1.2.1.25.2.3.1.2 剩余硬盘空间inode
集合所有oid信息的库，MIB库

snmp版本 v1 v2c v3
snmp 社区名==身份口令

2.监控windows

1.开启SNMP程序

2.启动服务

3.配置口令

4.zabbix server安装snmp工具

[root@zbx_server ~]#yum install net-snmp-utils.x86_64

测试

[root@zbx_server ~]# snmpwalk -c user -v2c    ip   oid

5.在zabbix server web界面添加主机

6.选择SNMP模板

7.修改宏(配置用户)

8.开启监控

默认1h更新最新数据，可以调整

9.监控linux

1.在linux上安装服务端

[root@zbx_server ~]#yum install net-snmp -y

2.修改配置文件

[root@zbx_server ~]#vim /etc/snmp/snmpd.conf
com2sec notConfigUser  default       public
# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   .1
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1

3.重启SNMP服务

[root@db ~]#systemctl start snmpd
[root@db ~]#systemctl status snmpd
● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
   Loaded: loaded (/usr/lib/systemd/system/snmpd.service; disabled; vendor preset: disabled)

4.测试是否能监控到值

[root@zbx_server ~]#snmpwalk -c public  -v2c 10.10.40.33 1.3.6.1.2.1.1
SNMPv2-MIB::sysDescr.0 = STRING: Linux db 3.10.0-957.12.2.el7.x86_64 #1 SMP Tue May 14 21:24:32 UTC 2019 x86_64
SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (6603) 0:01:06.03

4.在zabbix server web界面添加主机

SNMP协议已点亮
