我有一个非常简单的配置来收集Cisco交换机的接口统计信息 . 一开始，我只有这个：

[[inputs.snmp]]
  agents = [ "172.19.254.20:161" ]
  version = 2
  #interface
  community = "lalala"
  [[inputs.snmp.field]]
    name = "hostname"
    oid = "SNMPv2-MIB::sysName.0"
    is_tag = true

  [[inputs.snmp.table]]
    name = "interface"
    inherit_tags = [ "hostname" ]
    oid = "IF-MIB::ifTable"
    # Interface tag - used to identify interface in metrics database
    [[inputs.snmp.table.field]]
      name = "ifDescr"
      oid = "IF-MIB::ifDescr"
      is_tag = true

然后我注意到“HC”OID被遗漏了所以我添加了这个并在最后添加它 .

[[inputs.snmp.table]]
    name = "interface"
    inherit_tags = [ "hostname" ]
    oid = "IF-MIB::ifXTable"
    # Interface tag - used to identify interface in metrics database
    [[inputs.snmp.table.field]]
      name = "ifDescr"
      oid = "IF-MIB::ifDescr"
      is_tag = true

我测试了配置，它似乎很好 . 我也在使用wireshark验证我是否在HC OID上看到了查询 .

172.19.254.20.snmp > 172.19.1.170.41072:  { SNMPv2c C="pasonserver" { GetResponse(232) R=-1829944824  .1.3.6.1.2.1.31.1.1.1.6.222=0 .1.3.6.1.2.1.31.1.1.1.6.223=40124583293 .1.3.6.1.2.1.31.1.1.1.6.224=107009193941 .1.3.6.1.2.1.31.1.1.1.6.225=0 .1.3.6.1.2.1.31.1.1.1.6.226=2805121180775 .1.3.6.1.2.1.31.1.1.1.6.227=0 .1.3.6.1.2.1.31.1.1.1.6.228=23542578101 .1.3.6.1.2.1.31.1.1.1.6.240=268285249798 .1.3.6.1.2.1.31.1.1.1.6.241=162859292476670 .1.3.6.1.2.1.31.1.1.1.6.242=0 } }

我还继续看到旧的计数器/ OID已经填充了Influxdb中的新数据 .

> select ifInOctets from interface where ifIndex = '241' order by time desc limit 1;
name: interface
time                ifInOctets
----                ----------
1526337294000000000 3341483601

但是，如果我使用“ifHCInOctets”运行上面的查询，则没有返回值 . 我还验证了我在模式中有ifHCInOctets和其他“HC”计数器

> show field keys from interface
name: interface

我还重新启动了Influxdb和telegraf服务 . 我哪里做错了？谢谢！

忘了提到我运行的版本Telegraf v1.6.2（git：release-1.6 1fb4283f）InfluxDB shell版本：1.5.2
