首先挂os linux模板后发现网卡都是0
远程get发现是0

[root@iZ626l9a5x1Z ~]# zabbix_get -s 149.2.120.34 -k net.if.out[eth0]
0
在本监控主机上发现当前的网卡，确认正常！

[root@ns3723989 ~]# zabbix_agentd -t net.if.discovery
net.if.discovery                              [s|{"data":[{"{#IFNAME}":"teql0"},{"{#IFNAME}":"eth0"},{"{#IFNAME}":"docker0"},{"{#IFNAME}":"eth1"},{"{#IFNAME}":"dummy0"},{"{#IFNAME}":"bond0"},{"{#IFNAME}":"ifb0"},{"{#IFNAME}":"ip6tnl0"},{"{#IFNAME}":"ifb1"},{"{#IFNAME}":"sit0"},{"{#IFNAME}":"lo"},{"{#IFNAME}":"tunl0"}]}]
[root@ns3723989 ~]#

获取值，也正常

[root@ns3723989 ~]# zabbix_agentd -t net.if.out[eth0]
net.if.out[eth0]                              [u|18019795877]
[root@ns3723989 ~]# zabbix_agentd -t net.if.in[eth0]
net.if.in[eth0] 
                             [u|2307011385657]

重点参考这篇文字：http://neuro.me.uk/2009/09/20/revert-to-standard-ubuntu-kernel-on-ovh-or-kimsufi-servers/

重启zabbix-agentd，在server端测试

激动人心的时刻来了，踏马的还是没数据

[root@iZ626l9a5x1Z ~]# zabbix_get -s 149.2.120.34 -k eth0_input
0
[root@iZ626l9a5x1Z ~]# zabbix_get -s 149.2.120.34 -k eth0_output

然而，这样并没有解决问题
