The "value" 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.
You must tell Telegraf what type of metric to collect by using the
data_type configuration option. Available options are:
- integer
- float or long
- string
- 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.

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

## Each data format has its own unique set of configuration options, read
