File Input Plugin

This plugin reads the complete contents of the configured files in every interval. The file content is split line-wise and parsed according to one of the supported data formats.

If you wish to only process newly appended lines use the tail input plugin instead.

Introduced in: Telegraf v1.8.0 Tags: system OS support: all

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Parse a complete file each interval
[[inputs.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"]

  ## Character encoding to use when interpreting the file contents.  Invalid
  ## characters are replaced using the unicode replacement character.  When set
  ## to the empty string the data is not decoded to text.
  ##   ex: character_encoding = "utf-8"
  ##       character_encoding = "utf-16le"
  ##       character_encoding = "utf-16be"
  ##       character_encoding = ""
  # character_encoding = ""

  ## Data format to consume.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
  data_format = "influx"

  ## Please use caution when using the following options: when file name
  ## variation is high, this can increase the cardinality significantly. Read
  ## more about cardinality here:
  ## https://docs.influxdata.com/influxdb/cloud/reference/glossary/#series-cardinality

  ## Name of tag to store the name of the file. Disabled if not set.
  # file_tag = ""

  ## Name of tag to store the absolute path and name of the file. Disabled if
  ## not set.
  # file_path_tag = ""

Metrics

The format of metrics produced by this plugin depends on the content and data format of the file.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On February 3, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
