用于telegraf的opc-ua输入插件读取成功，但没有显示任何数据。

Question

我的计划是使用telegraf从wago中读取opc数据作为输入，并将数据作为输出发送到我的进水数据库。其他插件也可以工作，比如mqtt plugin...so，我可以验证是否正确地设置了进水数据库。

在我的telegraf.config里..。

# Retrieve data from OPCUA devices
[[inputs.opcua]]
  name = "opcua"
  endpoint = "opc.tcp://192.168.178.97:4840"
  connect_timeout = "10s"
  request_timeout = "5s"
  security_policy = "None"
  security_mode = "None"
  auth_method = "UserName"
  username = "admin"
  password = "wago"

  [[inputs.opcua.group]]
    namespace ="4"
    identifier_type ="s"
    nodes = [
      {name="IIoTgateway_xHeartbeat", namespace="4", identifier_type="s", identifier="|var|WAGO 750-8212 PFC200 G2 2ETH RS.Application.GVL_STATUS_PRG.IIoTgateway_xHeartbeat"},
]

使用工具UA专家.我可以验证xHeartbeat每1s改变一次.

​

telegraf插件的日志看起来也不错..。

​

登录到数据库(进水数据库)，我看到了变量，但没有任何更改.这里怎么了？在telegraf的文档中，有一个语句...about将namespaceIndex ..number从0设置为3....could，这就是问题所在，因为my namespaceIndex是4吗？

配置文件。

[global_tags]
[agent]
  interval = "500ms"
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 10000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  precision = "0s"
  hostname = ""
  omit_hostname = false

  [[inputs.opcua.group]]

    nodes = [
      {name="IIoTgateway_xHeartbeat", namespace="4", identifier_type="s",     identifier="|var|WAGO 750-8212 PFC200 G2 2ETH RS.Application.GVL_STATUS_PRG.IIoTgateway_xHeartbeat"},

    ]

  [[outputs.file]]
  ## Files to parse each interval.  Accept standard unix glob matching rules,
  ## as well as ** to match recursive files and directories.
    files = ["./tmp/metrics.out"]
    data_format = "influx"
    rotation_interval = "24h"
    rotation_max_archives = 10

在通过登录到container...data来检查./tmp/emeics.out文件之后，正确的.确保在流动中

from(bucket: "telegrafmqtt")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r["_measurement"] == "opcua")
  |> filter(fn: (r) => r["_field"] == "IIoTgateway_xHeartbeat")
|> toInt()

toInt()终于成功了.现在我看到了第1秒钟的心跳

最后，least...do不使用标准密码wago，而admin...this只是为了确保testing...also确保OPC连接的安全.
