VictoriaLogs supports given below Telegraf outputs:

Elasticsearch

Specify Elasticsearch output in the telegraf.toml for sending the collected logs to VictoriaLogs:

[[outputs.elasticsearch]]
  urls = ["http://localhost:9428/insert/elasticsearch"]
  timeout = "1m"
  flush_interval = "30s"
  enable_sniffer = false
  health_check_interval = "0s"
  index_name = "device_log-%Y.%m.%d"
  manage_template = false
  template_name = "telegraf"
  overwrite_template = false
  namepass = ["tail"]
  [outputs.elasticsearch.headers]
    "VL-Msg-Field" = "tail.value"
    "VL-Time-Field" = "@timestamp"
    "VL-Stream-Fields" = "tag.log_source,tag.metric_type"

[[inputs.tail]]
  files = ["/tmp/telegraf.log"]
  from_beginning = false
  interval = "10s"
  pipe = false
  watch_method = "inotify"
  data_format = "value"
  data_type = "string"
  character_encoding = "utf-8"
  [inputs.tail.tags]
     metric_type = "logs"
     log_source = "telegraf"

Loki

Specify Loki output in the telegraf.toml for sending the collected logs to VictoriaLogs:

[[outputs.loki]]
  domain = "http://localhost:9428"
  endpoint = "/insert/loki/api/v1/push&_msg_field=tail.value&_time_field=@timefield&_stream_fields=log_source,metric_type"
  namepass = ["tail"]
  gzip_request = true
  sanitize_label_names = true

[[inputs.tail]]
  files = ["/tmp/telegraf.log"]
  from_beginning = false
  interval = "10s"
  pipe = false
  watch_method = "inotify"
  data_format = "value"
  data_type = "string"
  character_encoding = "utf-8"
  [inputs.tail.tags]
     metric_type = "logs"
     log_source = "telegraf"

HTTP

Specify HTTP output in the telegraf.toml with batch mode disabled for sending the collected logs to VictoriaLogs:

[[inputs.tail]]
  files = ["/tmp/telegraf.log"]
  from_beginning = false
  interval = "10s"
  pipe = false
  watch_method = "inotify"
  data_format = "value"
  data_type = "string"
  character_encoding = "utf-8"
  [inputs.tail.tags]
     metric_type = "logs"
     log_source = "telegraf"

[[outputs.http]]
  url = "http://localhost:9428/insert/jsonline?_msg_field=fields.message&_time_field=timestamp,_stream_fields=tags.log_source,tags.metric_type"
  data_format = "json"
  namepass = ["docker_log"]
  use_batch_format = false

Substitute the localhost:9428 address inside endpoints section with the real TCP address of VictoriaLogs.

See these docs for details on headers specified in the [[output.elasticsearch]] section.

It is recommended verifying whether the initial setup generates the needed log fields and uses the correct stream fields.
