Dropping tag before appending to DB fails

Telegraf
1

Got an SNMP agent pulling stuff like so, but when I add tagexclude, it completely stops pushing metrics to database. I am using example from docs: telegraf/docs/CONFIGURATION.md at master · influxdata/telegraf · GitHub

Can anyone tell me what I am doing wrong? I want to remove the filtering tag I initially used from database

Here is my config

[[outputs.http]]
  url = "http://<DB>"

  data_format = "prometheusremotewrite"
  timeout = "15s"
  method = "POST"
#  tagexclude = ["destination"] <<<<<<<<< If I uncomment this, metrics don't push, but if its commented out its working.
  [outputs.http.tagpass]
    destination = ["medium"]

  [outputs.http.headers]
     Content-Type = "application/x-protobuf"
     Content-Encoding = "snappy"
     X-Prometheus-Remote-Write-Version = "0.1.0"

[[inputs.snmp]]
  interval = "60s"

  agents = ["udp4://<ROUTER_IP>"]
  timeout = "10s"
  version = 2
  path = ["/mibs"]
  unconnected_udp_socket = false
  community = "public"
  agent_host_tag = "source"
  retries = 3

  fieldinclude = [
    "*ifHCInUcastPkts", "*ifHCOutUcastPkts",
     "*ifInDiscards", "*ifOutDiscards", "*ifInErrors", "*ifOutErrors"
  ]

  [[inputs.snmp.table]]
    oid = "IF-MIB::ifXTable"
    index_as_tag = true

    [[inputs.snmp.table.field]]
      name = "ifName"
      oid = "IF-MIB::ifName"
      is_tag = true

  [[inputs.snmp.table]]
    oid = "IF-MIB::ifTable"
    index_as_tag = false

    [[inputs.snmp.table.field]]
      name = "ifName"
      oid = "IF-MIB::ifDescr"
      is_tag = true

  [inputs.snmp.tags]
    destination = "medium"

My bad it is working, it just didn’t show up in my dashboard because new metrics started appearing (without the label). You can test it by going to ‘Explore’ window in Grafana if thats how you visualise from your database
