Parser Processor Plugin

This plugin parses defined fields or tags containing the specified data format and creates new metrics based on the contents of the field or tag.

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 value in a specified field(s)/tag(s) and add the result in a new metric
[[processors.parser]]
  ## The name of the fields whose value will be parsed.
  parse_fields = ["message"]

  ## The name of the tags whose value will be parsed.
  # parse_tags = []

  ## If true, incoming metrics are not emitted.
  # drop_original = false

  ## Merge Behavior
  ## Only has effect when drop_original is set to false. Possible options
  ## include:
  ##  * override: emitted metrics are merged by overriding the original metric
  ##    using the newly parsed metrics, but retains the original metric
  ##    timestamp.
  ##  * override-with-timestamp: the same as "override", but the timestamp is
  ##    set based on the new metrics if present.
  # merge = ""

  ## The dataformat to be read from files
  ## 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"

Example

[[processors.parser]]
  parse_fields = ["message"]
  merge = "override"
  data_format = "logfmt"
Input
