File Output Plugin

This plugin writes metrics to one or more local files in one of the supported data formats.

Introduced in: Telegraf v0.10.3 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

# Send telegraf metrics to file(s)
[[outputs.file]]
  ## Files to write to, "stdout" is a specially handled file.
  files = ["stdout", "/tmp/metrics.out"]

  ## Use batch serialization format instead of line based delimiting.  The
  ## batch format allows for the production of non line based output formats and
  ## may more efficiently encode and write metrics.
  # use_batch_format = false

  ## The file will be rotated after the time interval specified.  When set
  ## to 0 no time based rotation is performed.
  # rotation_interval = "0h"

  ## The logfile will be rotated when it becomes larger than the specified
  ## size.  When set to 0 no size based rotation is performed.
  # rotation_max_size = "0MB"

  ## Maximum number of rotated archives to keep, any older logs are deleted.
  ## If set to -1, no archives are removed.
  # rotation_max_archives = 5

  ## Data format to output.
  ## 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_OUTPUT.md
  data_format = "influx"

  ## Compress output data with the specified algorithm.
  ## If empty, compression will be disabled and files will be plain text.
  ## Supported algorithms are "zstd", "gzip" and "zlib".
  # compression_algorithm = ""

  ## Compression level for the algorithm above.
  ## Please note that different algorithms support different levels:
  ##   zstd  -- supports levels 1, 3, 7 and 11.
  ##   gzip -- supports levels 0, 1 and 9.
  ##   zlib -- supports levels 0, 1, and 9.
  ## By default the default compression level for each algorithm is used.
  # compression_level = -1

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
