Telegraf无法从Arista MIB中提取路由表信息

Question

所以我试着从一些阿瑞斯那里收集路由数据。

当我跑来跑去的时候，一切似乎都正常.

ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv4.other = Gauge32: 3 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv4.connected = Gauge32: 8 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv4.static =Gauge32 26 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv4.ospf = Gauge32: 542 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv4.bgp = Gauge32: 1623 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.附件= Gauge32: 12 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv6.other = Gauge32: 25 ARISTA-FIB-STATS-MIB：：aristaFIBStatsTotalRoutesForRouteType.ipv6.other= Gauge32: 3 ARISTA-FIB-STATS-MIB::aristaFIBStatsTotalRoutesForRouteType.ipv6.internal = Gauge32：

但当我试图用telegraf提取数据时，我会得到不同的信息.

BGP，agent_host=10.45.100.20，host=nw01.ny5，hostname=CR.NY aristaFIBStatsTotalRoutesForRouteType=2i 1654976575000000000 BGP，agent_host=10.45.100.20，host=nw01.ny5，hostname=CR.NY aristaFIBStatsTotalRoutes=2260i 1654976575000000000 BGP，agent_host=10.45.100.20，host=nw01.ny5，hostname=CR.NY aristaFIBStatsTotalRoutesForRouteType=8i 16549765750000000 BGP，agent_host=10.45.100.20，host=nw01.ny5，hostname=CR.NY aristaFIBStatsTotalRoutesForRouteType=63i 16549765750000000

根据MIB文件..。

https://www.arista.com/assets/data/docs/MIBS/ARISTA-FIB-STATS-MIB.txt

它使用的是IANA-RTPROTO-MIB.txt协议定义，但我不知道从哪里得到这些信息，因为通过telegraf检索到的数据没有向我显示任何信息。有人知道怎么处理这事吗？

首先，您可能希望通过在index_as_tag = true中设置inputs.snmp.table来使telegraf返回返回行的索引。

然后，在配置中添加以下处理器：

# Parse aristaFIBStatsAF and aristaFIBStatsRouteType from index for BGP table
[[processors.regex]]
  namepass = ["BGP"]
  order = 1

  [[processors.regex.tags]]
    ## Tag to change
    key = "index"
    ## Regular expression to match on a tag value
    pattern = "^(\\d+)\\.(\\d+)$"
    replacement = "${1}"
    ## Tag to store the result
    result_key = "aristaFIBStatsAF"

  [[processors.regex.tags]]
    ## Tag to change
    key = "index"
    ## Regular expression to match on a tag value
    pattern = "^(\\d+)\\.(\\d+)$"
    replacement = "${2}"
    ## Tag to store the result
    result_key = "aristaFIBStatsRouteType"


# Rename index to aristaFIBStatsAF for BGP table with single index row
[[processors.rename]]
  namepass = ["BGP"]
  order = 2

  [[processors.rename.replace]]
    tag = "index"
    dest = "aristaFIBStatsAF"

  [processors.rename.tagdrop]
    aristaFIBStatsAF = ["*"]


# Translate tag values for BGP table
[[processors.enum]]
  namepass = ["BGP"]
  order = 3
  tagexclude = ["index"]

  [[processors.enum.mapping]]
    ## Name of the tag to map
    tag = "aristaFIBStatsAF"

    ## Table of mappings
    [processors.enum.mapping.value_mappings]
      0 = "unknown"
      1 = "ipv4"
      2 = "ipv6"

  [[processors.enum.mapping]]
    ## Name of the tag to map
    tag = "aristaFIBStatsRouteType"

    ## Table of mappings
    [processors.enum.mapping.value_mappings]
      1   = "other"
      2   = "connected"
      3   = "static"
      8   = "rip"
      9   = "isIs"
      13  = "ospf"
      14  = "bgp"
      200 = "ospfv3"
      201 = "staticNonPersistent"
      202 = "staticNexthopGroup"
      203 = "attached"
      204 = "vcs"
      205 = "internal"

免责声明:没有在telegraf中测试这个，所以可能有一些错误
