Value input data format	Use the "value" input data format to parse single values into Telegraf metrics.	telegraf_1_14 name weight parent Value 100 Input data formats (parsers)

The "value" input data format translates single values into Telegraf metrics. This is done by assigning a measurement name and setting a single field ("value") as the parsed metric.

Configuration

You must tell Telegraf what type of metric to collect by using the data_type configuration option. Available data type options are:

1. integer
2. float or long
3. string
4. boolean

Note: It is also recommended that you set name_override to a measurement name that makes sense for your metric; otherwise, it will just be set to the name of the plugin.

[[inputs.exec]]
  ## Commands array
  commands = ["cat /proc/sys/kernel/random/entropy_avail"]

  ## override the default metric name of "exec"
  name_override = "entropy_available"
