Carbon2 output data format

Use the carbon2 output data format (serializer) to format and output Telegraf metrics as Carbon2 format.


  ## Files to write to, "stdout" is a specially handled file.
  files = ["stdout", "/tmp/metrics.out"]

  ## Data format to output.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  data_format = "carbon2"

Standard form:

metric=name field=field_1 host=foo  30 1234567890
metric=name field=field_2 host=foo  4 1234567890
metric=name field=field_N host=foo  59 1234567890


The serializer converts the metrics by creating intrinsic_tags using the combination of metric name and fields. So, if one Telegraf metric has 4 fields, the carbon2 output will be 4 separate metrics. There will be a metric tag that represents the name of the metric and a field tag to represent the field.


If we take the following InfluxDB Line Protocol:

weather,location=us-midwest,season=summer temperature=82,wind=100 1234567890

After serializing in Carbon2, the result would be:

metric=weather field=temperature location=us-midwest season=summer  82 1234567890
metric=weather field=wind location=us-midwest season=summer  100 1234567890

Fields and tags with spaces

When a field key or tag key-value have spaces, spaces will be replaced with _.

Tags with empty values

When a tag’s value is empty, it will be replaced with null.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
