将SNMP陷阱发送到Nagios中的特定主机

我有两台主机的nagios。一个是localhost（10.10.62.5），另一个是 ubuntu（10.10.62.10）。我在本地主机上设置了nagios监视器

主机配置文件如下所示

localhost.cfg：

define host{
    use                     linux-server           
    host_name               localhost
    alias                   localhost
    address                 10.10.62.5
    }

define service{ 
host_name       localhost   
service_description WSN_COUNT   
is_volatile     1   
check_command       check-host-alive    
max_check_attempts  1
normal_check_interval   1
retry_check_interval    1
active_checks_enabled   0   
passive_checks_enabled  1   
check_period        24x7    
notification_interval   31536000    
notification_period 24x7    
notification_options    w,u,c   
notifications_enabled   1
 }

ubuntu.cfg：

define host{
  use    linux-server
  host_name ubuntu
  alias  ubuntu
  address    10.10.62.10
}
define service{ 
host_name    localhost  
service_description WSN_COUNT   
is_volatile  1  
check_command    check-host-alive   
max_check_attempts  1
normal_check_interval   1
retry_check_interval    1
active_checks_enabled   0   
passive_checks_enabled  1   
check_period     24x7   
notification_interval   31536000    
notification_period 24x7    
notification_options    w,u,c   
notifications_enabled   1
}

MIB文件：

NAGIOS-TRAP-TEST-MIB DEFINITIONS ::= BEGIN
IMPORTS enterprises FROM SNMPv2-SMI;

nagiostests OBJECT IDENTIFIER ::= { enterprises 0 }
nagiostraps OBJECT IDENTIFIER ::= { nagiostests 1 }
nagiosnotifs OBJECT IDENTIFIER ::= { nagiostests 2 }

WSNcount NOTIFICATION-TYPE
        OBJECTS { sysLocation }
        STATUS current
        DESCRIPTION "SNMPv2c notification"
        ::= { nagiosnotifs 9 }
END

我使用snmptt（netsnmp）将陷阱与nagios集成。配置文件是

snmptt.conf.local：

    EVENT WSNcount .1.3.6.1.4.1.0.2.1 "Status Events" Normal
FORMAT SNMPv2c notification $*
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result localhost WSN_COUNT 1 "SNMPv2c notification $*"
SDESC
SNMPv2c notification
Variables:
  1: sysLocation
EDESC

    EVENT WSNcount .1.3.6.1.4.1.0.2.1 "Status Events" Normal
FORMAT SNMPv2c notification $*
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result ubuntu WSN_COUNT 1 "SNMPv2c notification $*"
SDESC
SNMPv2c notification
Variables:
   1: sysLocation
EDESC

snmptt.conf.local：

    EVENT WSNcount .1.3.6.1.4.1.0.2.1 "Status Events" Normal
FORMAT SNMPv2c notification $*
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result localhost WSN_COUNT 1 "SNMPv2c notification $*"
SDESC
SNMPv2c notification
Variables:
  1: sysLocation
EDESC

    EVENT WSNcount .1.3.6.1.4.1.0.2.1 "Status Events" Normal
FORMAT SNMPv2c notification $*
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result ubuntu WSN_COUNT 1 "SNMPv2c notification $*"
SDESC
SNMPv2c notification
Variables:
   1: sysLocation
EDESC

当我使用下面的命令从ubuntu（10.10.62.10）机器发送陷阱时，陷阱发送到nagios中的两台主机

    snmptrap -v 2c -c private 10.10.62.5 "" NAGIOS-TRAP-TEST-MIB::RFIDcount SNMPv2-MIB::sysLocation.0 s "snmptest trap"

请帮助我将陷阱发送给特定的主机。。怎么可能

我认为您误解了SNMP陷阱是什么。SNMP陷阱是从网络设备（如路由器、交换机、刀片、群集等）发送到监控系统/服务的SNMP消息

我猜您要做的是在MIB文件中搜索要监视的特定网络设备，并搜索与要从该特定设备收集的信息相匹配的OID

要通过SNMP监控的设备必须在其配置中启用SNMP（基于Web或其他方式）

您可以对此设备执行SNMPwalk以查看所有可用的OID：

snmpwalk -v 2c -c public <ip address network device>

---

您现在可以在Nagios的服务定义中使用此检查。

请帮助我。您正在从10.10.62.10发送SNMP陷阱到10.10.62.5，但Nagios会为两台主机显示它吗？
